<p class="fs16 lh14">The fight for cloud supremacy is a three-way fight between <strong>AWS, Azure, and Google Cloud</strong> Platform. Fresher may consider only pricing while selecting a public cloud service provider. However, there are other elements to consider when determining the winner of this cloud duel. This post will provide you with a detailed <strong>comparison of Amazon Web Services, Microsoft Azure, and Google Cloud.</strong></p>
<p class="fs16 lh14">Cloud computing has come a long, It's no longer a question of whether to use cloud computing; it's a question of which cloud platform to use. With so many cloud providers on the market, Amazon Web Services, Microsoft Azure, and Google Cloud Platform boldly stand out as the top three. So, how do you pick one? How do you resolve the great <strong>AWS vs. Azure vs. Google Cloud debate?</strong></p>
<p class="fs16 lh14">This blog on <strong>AWS vs. Azure vs. Google Cloud</strong> compares and contrasts the major comparison factors between AWS, Azure, and GCP. This blog compares Azure vs. AWS vs. Google Cloud.</p>
<p class="fs16 lh14"> </p>
<h2 class="fs16 lh14"><strong>AWS Vs Azure Vs Google Cloud: Establishment</strong></h2>
<h3 class="fs16 lh14"><strong>Amazon Web Services</strong></h3>
<p class="fs16 lh14">Amazon Web Services is a cloud computing platform. Amazon Web Services is owned by Amazon that provides a subscription-based on-demand Cloud Computing platform to people, businesses, and governments.</p>
<p class="fs16 lh14">Amazon Web Services has a larger user base, as well as higher levels of trust and reliability, as one of the earliest cloud providers.</p>
<p class="fs16 lh14">AWS was first made public in 2006, with services including Elastic Compute Cloud (EC2) and Simple Storage Service (Amazon S3). Amazon Cloud Front, Content Delivery Network (CDN), and other services joined the AWS Cloud Computing Service in 2009.</p>
<h3 class="fs16 lh14"><strong>Microsoft Azure</strong></h3>
<p class="fs16 lh14">Azure is a service provided by Microsoft.</p>
<p class="fs16 lh14">Microsoft Azure, formerly known as Azure, was introduced in 2010 with the goal of providing organizations with a reliable Cloud Computing platform. In 2014, Azure was rebranded to ‘Microsoft Azure,' while the term ‘Azure' is still widely used. Microsoft Azure has made significant progress in comparison to its competitors since its beginnings.</p>
<h3 class="fs16 lh14"><strong>Google Cloud Platform</strong></h3>
<p class="fs16 lh14">Google Cloud Platform is developed and owned by Google.</p>
<p class="fs16 lh14">Google Cloud Platform (GCP) is that run on the same infrastructure that Google uses internally for its end-user products such as the Google Search engine, YouTube, and others.</p>
<p class="fs16 lh14">Google Cloud Platform began its journey in 2011 and has managed to establish a strong position in the cloud business in less than a decade. Google Cloud was created with the intention of bolstering Google's own products, such as the Google Search engine and YouTube. However, they have now launched their enterprise services, allowing anyone to access the Google Cloud Platform, which is built on the same infrastructure as Google Search and YouTube.</p>
<h2 class="fs16 lh14"><strong>AWS, Azure, and Google Cloud Availability Zones</strong></h2>
<p class="fs16 lh14">The fact that AWS was the first in the cloud sector has already been proven, implying that they have had more time to create and expand their network. As a result, AWS hosts in multiple locations throughout the world. Azure and GCP both have various locations around the world, but the distinction is in the number of availability zones they have.</p>
<p class="fs16 lh14">AWS has 66 zones, with 12 more to come in the future, Azure has 54 regions worldwide and is available in 140 countries; and Google Cloud Platform is available in 20 regions worldwide, with 3 more in coming years.</p>
<p class="fs16 lh14">Let's continue with this Azure vs. AWS vs. Google battle.</p>
<h2 class="fs16 lh14"><strong>Market Shares and Growth Rates for AWS, Azure, and Google Cloud</strong></h2>
<p class="fs16 lh14">Microsoft's Azure cloud revenue has been noted to beat both AWS and Google Cloud combined, according to announced quarterly earnings for 2021.</p>
<p class="fs16 lh14">Despite Amazon's AWS' Goliath-like height, Microsoft's Azure cloud surpassed its competition with US$17.7 billion in commercial-cloud revenue (a 50 percent increase over the previous quarter), according to the fiscal earnings report. While Amazon's AWS claimed US$13.5 billion in cloud revenue for the quarter (up 32% from the previous quarter), Google Cloud only recorded US$4.05 billion.</p>
<p class="fs16 lh14">This quarter, the worldwide cloud market increased by 35% to $41.8 billion. AWS accounts for 32% of the market, with Azure accounting for 19% and Google accounting for 7%.</p>
<h2 class="fs16 lh14"><strong>Who Uses AWS, Azure, and Google Cloud?</strong></h2>
<p class="fs16 lh14">Because AWS is the oldest player in the cloud business, it has a larger user base and community support. So, AWS has a larger number of high-profile and well-known clients, including Netflix, BMW, Samsung, MI and others.</p>
<p class="fs16 lh14">With time, Azure is getting a larger number of high-profile customers. Azure currently boasts about 80% of Fortune 500 firms as customers. Honeywell, Apple, and others are among its key clients.</p>
<p class="fs16 lh14">Google Cloud uses the same for Google search and YouTube, So it is used by many enterprises and highly trust Google Cloud. HSBC, PayPal, 20th Century Fox, Bloomberg, Dominos, and others are among Google Cloud's many clients.</p>
<p class="fs16 lh14">All of these cloud service providers provide a variety of cloud computing services that are necessary for any basic organization. The difference is in the number of services available. So, to continue with this Azure vs. AWS vs. Google Cloud comparison, let's have a look at the service offers of these cloud providers.</p>
<h2 class="fs16 lh14"><strong>AWS vs. Azure vs. Google Cloud: What's the Difference?</strong></h2>
<p class="fs16 lh14">Now you can discover what services each of these three cloud behemoths has to offer.</p>
<p class="fs16 lh14">AWS computing services are far and away from the most advanced and functionally rich, thanks to a five-year head start. AWS has more than 200 services, whilst Azure has more than 100. On the other hand, Google Cloud is catching up to Azure and AWS, offering roughly 60 services.</p>
<p class="fs16 lh14">Let's conclude up this Azure vs. AWS vs. Google Cloud blog by looking at the most important advantages and disadvantages of these three cloud giants. So, based on all of the aforementioned parameters, which cloud provider would be declared the winner?</p>
<ul>
<li class="db">AWS is the clear winner here, with a five-year head start.</li>
<li class="db">AWS wins in this category because it has a larger number of regions and availability zones.</li>
<li class="db">Market share: AWS comes out on top with almost one-third of the market share.</li>
<li class="db">GCP is the clear winner, with an almost 100% growth rate.</li>
<li class="db">Who makes use of them: It's a tie because all three cloud platforms are used by high-end customers.</li>
<li class="db">AWS comes out on top when it comes to the number of services available.</li>
<li class="db">Azure wins in terms of integration with open-source and on-premise systems, such as Microsoft tools, which are widely used in practically all enterprises.</li>
<li class="db">Models of Pricing: Google Cloud is the clear winner here, with more customer-friendly pricing and discount structures.</li>
</ul>
<p class="fs16 lh14">With a higher point total in this cloud duel of Azure vs. AWS vs. Google Cloud, AWS handily defeats all of the main cloud providers today. However, considering that Azure and GCP are continuously working their way up the top cloud providers list, it's difficult to determine how long AWS will have the title of leading cloud provider.</p>
<p class="fs16 lh14">Despite the fact that AWS has the distinction of being the first of its kind, Azure and GCP each offer their own set of advantages. Several firms that utilize Microsoft tools choose Azure cloud since it is simple to integrate MS tools with Azure cloud. The only reason consumers should choose GCP is that it offers the best pricing plan for the infrastructure that runs Google Search and YouTube.</p>
<p class="fs16 lh14">So, all things considered, it's better to say that it's not about picking the finest cloud providers; rather, it's about picking the cloud provider that's most suited to your needs.</p>

AWS & Azure & GCP service comparison, Here we discuss about the three best services in detail and their usages widely. At the end of this blog, you will get an idea about each service and you shall be able to choose one of the cloud services according to your usage.

AWS & AZURE & GCP service comparison

<p class="fs16 lh14"><strong>DevOps</strong> is a set of technologies and techniques that a company can use to generate apps and services more quickly than with traditional software development methods. Because of this speed, businesses can better serve their customers and compete in the market.</p>
<p class="fs16 lh14">Development and operations teams collaborate across the whole software application life cycle, from development and testing to deployment and operations, in a DevOps paradigm.</p>
<p class="fs16 lh14"><strong>DevOps</strong> shortens the time it takes to provide applications and software services at a high rate. So that businesses can learn about and adapt to the market as soon as possible. It also reduces risk by consistently delivering and soliciting feedback from end-users and customers at an early stage.</p>
<p class="fs16 lh14"><strong>DevOps</strong> is a culture and set of techniques that bring together development and operations teams to finish software development. It enables businesses to create and enhance products more quickly than they could with traditional software development methods.</p>
<h2 class="fs16 lh14"><strong>Benefits of DevOps</strong></h2>
<h3><strong>High Speed</strong></h3>
<p class="fs16 lh14">DevOps allows developers to monitor the device throughout its development cycle for any app modifications or bugs. This reduces the time it takes to track, find, and fix defects, allowing you to get to market faster.</p>
<p class="fs16 lh14">You can also use the DevOps model to innovate faster with customers, better respond to changing markets, and be more successful at generating business outcomes.</p>
<h3><strong>Rapid Delivery</strong></h3>
<p class="fs16 lh14">Continuous integration and delivery, a rapid feedback loop, and continuous monitoring are the basic ideas of DevOps, which make agile software development processes faster and more efficient.</p>
<p class="fs16 lh14">By cultivating a shared DevOps culture, it allows for quick and consistent reviews, ensuring that any defects are fixed as soon as possible.</p>
<h3><strong>Enhanced Collaboration</strong></h3>
<p class="fs16 lh14">You may develop more productive teams by implementing the DevOps cultural paradigm, which emphasizes ideas like ownership and responsibility. Now that developers and operations departments collaborate well, share many jobs, and consolidate workflows, errors are reduced and time is saved while collaboration improves.</p>
<h3><strong>Improved Security</strong></h3>
<p class="fs16 lh14">Automatic enforcement rules, fine-grained controls, and configuration management approaches are used in the DevOps model to allow developers to move swiftly while maintaining leverage and adhering to compliance regulations. Using infrastructure as code and policy as code, for example, you can describe and then monitor enforcement at scale.</p>
<h3><strong>Greater Scalability</strong></h3>
<p class="fs16 lh14">DevOps automation and continuity make it possible to navigate dynamic (navigation menu) or changing processes efficiently and safely. Infrastructure as code, for example, allows you to handle production settings, testing, and output in a more predictable and efficient manner, resulting in increased scalability.</p>
<h3><strong>Early Error Detection</strong></h3>
<p class="fs16 lh14">The integrated DevOps environment fosters a community of information-sharing across departments. Automatic, continuous monitoring and ongoing code testing tend to increase the overall performance of the building as a business outcome.</p>
<p class="fs16 lh14">It helps to discover and solve flaws early when DevOps teams are encouraged to share their suggestions with one another.</p>
<h3><strong>Risk Management</strong></h3>
<p class="fs16 lh14">We may identify the risk factor early in the application lifecycle phases using this method. Staying ahead of the competition requires early detection of any faults or bugs, as well as prompt correction or remedies.</p>
<h3><strong>Monitoring and Logging</strong></h3>
<p class="fs16 lh14">Businesses track metrics and logs to see how application and system performance affects the end-user experience of their product. By capturing, categorizing, and then analyzing data and logs created by applications and infrastructure, businesses can learn how code changes or updates affect customers.</p>
<h3><strong>Production Support</strong></h3>
<p class="fs16 lh14">Engineers in this model not only work on new updates but also within an existing solution in a development environment, focusing on tackling critical security vulnerabilities in real-time.</p>
<p class="fs16 lh14">While they are the third and final team to be interested in fixing manufacturing problems, this is a common occurrence that offers them with insights into production issues that, in turn, aid them in designing better solutions.</p>
<h2 class="fs28 cb mdtp15 lh15 mlh14"><strong>How does DevOps Works?</strong></h2>
<p class="fs16 lh14">DevOps is a practice in which operations and development engineers collaborate throughout the project lifecycle, from design to development to release and support.</p>
<p class="fs16 lh14">The team works collaboratively to achieve the intended goal, from design and development to testing automation to continuous integration to continuous delivery. People with both development and operations skill sets collaborate and use CI-CD and monitoring tools to respond fast to client requests and resolve issues and defects.</p>
<p class="fs16 lh14">Several variations of the development pattern are introduced by DevOps. Most analysts, on the other hand, believe that the following capabilities are shared by practically all communities.</p>
<p class="fs16 lh14">DevOps processes require a lot of automation, and the underlying premise of DevOps is to automate everything. After the code part, the application and system are monitored in production.</p>
<p class="fs16 lh14">The major focus of DevOps methodology is automating infrastructure setup and setups, as well as software deployment. DevOps methodology is reliant on automation to deliver in a matter of hours and on a regular basis across platforms.</p>
<p class="fs16 lh14">DevOps automation improves speed, consistency, correctness, and reliability while also increasing the quantity of delivery. DevOps automation encompasses the entire development, deployment, and monitoring process.</p>
<h2 class="fs16 lh14"><strong>DevOps Principles</strong></h2>
<p class="fs16 lh14">While it is a functional technique, it is really a mindset and culture revolution in a company. The following are the fundamental principles that underpin this theory:</p>
<p class="fs16 lh14"><strong>Automation:</strong> Ops uses the automation principle to automate everything, including workflows, code reviews, and infrastructure provisioning to reduce duplication and overwork.</p>
<p class="fs16 lh14"><strong>Iteration:</strong> It writes small bits of code during a time-box sprint to support software updates and sub-releases that speed up the speed and length of launches.</p>
<p class="fs16 lh14"><strong>Continuous Improvement:</strong> They constantly test, learn from mistakes, and act on input in order to maximize efficiency, cost, and time for implementation.</p>
<p class="fs16 lh14"><strong>Continuous Testing:</strong> The DevOps environment uses continuous testing to enable faster releases while also improving quality assurance.</p>
<p class="fs16 lh14"><strong>Collaboration:</strong> DevOps brings developers and operations together to maximize efficiency and get faster results.</p>
<h2 class="fs16 lh14"><strong>TOOL:</strong></h2>
<p class="fs16 lh14">Git is a DevOps technology that is commonly used in the software industry. It's a distributed SCM (source code management) application that's well-known for its open-source collaboration and planning capabilities, and it's widely used to track the progress of development work by distant teams and open source contributors. Check-in, commits, branches, merging, labels, push and pull to/from GitHub, and other version control functions are all supported.</p>
<p class="fs16 lh14">To integrate Git into your existing process, you'll need to use services like GitHub and Bitbucket to host repositories where team members may push their work. You can gain free access to public repositories with GitHub, which is a great solution for most projects. Bitbucket and GitHub both offer easy interfaces. If you combine it with Slack, for example, your team members will be notified anytime a new contribution is made.</p>

What is DevOps and how its works, Here we also discuss about the benefits, principles, tools?

What is DevOps and how its works

<h2 class="fs16 lh14"><strong>Communication and Collaboration Skills</strong></h2>
<p class="fs16 lh14">Software development, testing, and deployment become more collaborative with <strong>DevOps.</strong> It brings together small groups with different goals to collaborate toward more efficient and high-quality code releases. Communication skills (both verbal and written) are a must for a successful DevOps engineer because there cannot be any boundaries between the different personas.</p>
<p class="fs16 lh14">Engineers must communicate with internal management teams involved in the<strong> DevOps</strong> process on a frequent basis to stay informed about the project's objectives, roadmap, blocking issues, and other issues. They must also communicate efficiently with clients regarding support difficulties.</p>
<p class="fs16 lh14">Communication is important, but so is the capacity to work together. <strong>DevOps engineers</strong> should work well with others and help one another during sprints or software revisions. You should be able to mentor and advise team members on the best ways to provide code, what tools to use when coding, and how to test the latest features, in addition to simply being a good teammate.</p>
<h2 class="fs28 cb mdtp15 lh15 mlh14">Specific Programming Skills with Mature Coding Standards</h2>
<p class="fs16 lh14">Though all development methodologies involve programming abilities, <strong>DevOps engineers</strong> have their own set of coding duties. A <strong>DevOps engineer</strong> should be familiar with many scripting languages, such as Java, JavaScript, Ruby, Python, PHP, Bash, and others, rather than specializing in one. A DevOps engineer should be at ease authoring and debugging bugs in these languages, as well as in OS environments.</p>
<p class="fs16 lh14">These coding abilities should be used by DevOps engineers to either orchestrate a stable and efficient pipeline that is as automated as feasible or to create new tools that can automate phases in the pipeline to improve team activities.</p>
<p class="fs16 lh14">More critically, a DevOps engineer should be well-versed in test automation. You must first write clean code in several languages, then ensure that your code seamlessly interfaces with that of other teams — often in different settings.</p>
<h2 class="fs28 cb mdtp15 lh15 mlh14">Non-functional DevOps skills</h2>
<p class="fs16 lh14"><strong>DevOps engineers </strong>must be skilled in monitoring production environments and performance measures, as well as security and cloud administration, in addition to “soft” talents. This ensures that fresh builds perform as expected in production. Infrastructure as Code (IaC) enables velocity and automation in many enterprises. As a result, a DevOps engineer should be familiar with these technologies (or, at a larger organization that includes multiple DevOps engineers.</p>
<p class="fs16 lh14">Finally, DevOps, which incorporates security measures into DevOps operations, is quickly becoming a critical component of the pipeline. DevOps engineers should take an active role in assuring the security of the supplied code on a continual basis because DevOps demands that code be delivered swiftly in small pieces.</p>
<h2 class="fs28 cb mdtp15 lh15 mlh14"><span style="color: #2b2b2b;">Technical Support and Maintenance Skills</span></h2>
<p class="fs16 lh14"><span style="color: #2b2b2b;"><strong>DevOps engineers</strong> don't just work on the development side; they also support and manage a unified workflow that incorporates IT operations. A DevOps engineer is responsible for the core tools and environments used by the whole DevOps team, which may include customer-facing skills. This implies a DevOps engineer should be able to serve both internal and external clients, as well as troubleshoot problems as they emerge.</span></p>
<p class="fs16 lh14"><span style="color: #2b2b2b;">A <strong>DevOps engineer</strong> should also be able to assure the uptime and availability of production systems. This implies that DevOps engineers should be able to:</span></p>
<p class="fs16 lh14"><span style="color: #2b2b2b;">• Get proper warnings when something is wrong or unavailable<br />• Monitor the products in real-time Assist in the resolution of issues via online support or technical troubleshooting.</span></p>
<p class="fs16 lh14"><span style="color: #2b2b2b;"><br />DevOps management requires the solution to be up and running 24 hours a day, seven days a week, and the DevOps engineers are at the heart of this.</span></p>
<h2 class="fs28 cb mdtp15 lh15 mlh14"><strong>Linux Fundamentals and Scripting</strong></h2>
<p class="fs16 lh14">The days of companies being concerned about proprietary operating systems are long gone. We are now living in the Linux era. The majority of businesses prefer to run their apps on Linux. As a result, a <strong>DevOps Engineer's</strong> ability to work with the Linux operating system is critical.</p>
<p class="fs16 lh14">In addition, most configuration management technologies, such as Puppet, Chef, and have Linux master nodes. DevOps is a type of automation that incorporates infrastructure provisioning automation. More information on DevOps tools may be found here. </p>
<h2 class="fs28 cb mdtp15 lh15 mlh14"><strong>Infrastructure as Code</strong></h2>
<p class="fs16 lh14">Previously, deploying IT infrastructure was a time-consuming, labor-intensive procedure. With the advent of cloud computing and containerization technologies, developers can now provision infrastructure using an automated script. The script runs the necessary tasks and manages the configuration using one of the available configuration management tools. In a matter of seconds, the appropriate application platform or infrastructure is given.</p>
<h2 class="fs28 cb mdtp15 lh15 mlh14"><strong>Soft skills</strong></h2>
<p class="fs16 lh14">With the advent of the DevOps paradigm, soft skills are becoming increasingly important in the IT business. Most businesses choose an agile approach based on DevOps principles, which allows teams to work at a high rate and generate deliverables quickly in order to fulfill customer expectations. Soft skills are becoming increasingly important in the DevOps era.</p>
<h2 class="fs28 cb mdtp15 lh15 mlh14"><strong>Security Skills</strong></h2>
<p class="fs16 lh14">Hackers can easily gain access to systems by exploiting weaknesses, undermining the system in place to gain access to the data.</p>
<p class="fs16 lh14">DevOps allows for a faster cycle of code creation and deployment, which means vulnerabilities are more likely to be introduced into the code than they have ever been previously. As a result, engineers must be able to develop safe code in order to prevent applications from unwanted attacks, as well as ensure that systems are protected against typical cyber security flaws.</p>
<p class="fs16 lh14">When working as a <strong>DevOps engineer</strong>, it's critical to have security expertise because it's far better to put safe software in from the start than to add it later. If security isn't in place from the start, there's a greater likelihood that hackers may introduce harmful code into the network. As a result, when hiring the next DevOps engineer, make sure security is at the top of the list of requirements.</p>
<h2 class="fs28 cb mdtp15 lh15 mlh14"><strong>Conclusion</strong> </h2>
<p class="fs16 lh14">Individuals from various functions collaborate on DevOps to achieve the same goal: rapid, continuous delivery of high-quality code. <strong>DevOps engineers</strong> are the engine that propels the team forward in this attempt. They are the ones who enable practitioners to efficiently fulfill their customers by using automated tools, testing, orchestration methodologies, and communication.</p>
<p class="fs16 lh14">As the market evolves, it's only natural for the DevOps engineer's position to expand and absorb more duties, particularly in non-functional areas like security and monitoring analytics. Start by concentrating on the abilities and duties outlined here, and you'll find that you're in high demand.</p>
<p class="fs16 lh14">If you're new to the DevOps realm, the list of DevOps skills may appear daunting. However, these are the core DevOps engineer abilities that employers are seeking, and mastering them will give your resume a leg up. We hope that this post helped to clarify the DevOps abilities needed for a successful career.</p>

DevOps engineer technical skill, there is a number of skills which basically needed to be an engineer in DevOps, this blog details what are the skills needed to be a DevOps engineer.

DEVOPS ENGINEER TECHNICAL SKILLS

<h1 class="fs28 cb mdtp15 lh15 mlh14">DevOps Principles</h1>
<p class="fs16 lh14">Collaboration, communication, sharing, transparency, and a holistic approach to software development are all part of the DevOps mindset. DevOps is based on a wide range of ideas and methodologies. They ensure that high-quality software is delivered on time. How to organise a DevOps environment is guided by <strong>DevOps principles.</strong></p>
<h2 class="fs16 lh14"><strong>Flow/systems thinking</strong></h2>
<p class="fs16 lh14">This stresses the overall system's performance rather than the performance of a single silo of work or department - this can be as large as a division.</p>
<p class="fs16 lh14">It starts with identifying needs, which are then constructed in Development and finally transferred to IT Operations, where the value is supplied to the customer as a service.</p>
<p class="fs16 lh14">Never transmitting a known fault to downstream work centres, never permitting local optimization to cause global degradation, constantly attempting to boost flow, and always seeking to obtain profound insight into the system are all effects of putting the First Way into reality.</p>
<h2 class="fs28 cb mdtp15 lh15 mlh14">Amplify feedback loops</h2>
<p class="fs16 lh14">The goal is to create right-to-left feedback loops. Almost every process improvement project aims to shorten and magnify feedback loops so that essential modifications can be made on a regular basis.</p>
<p class="fs16 lh14">Understanding and responding to all consumers, both internal and external, shortening and amplifying all feedback loops, and embedding knowledge where we need it are all results of the Second Way.</p>
<h2 class="fs28 cb mdtp15 lh15 mlh14">Culture of continual experimentation and learning</h2>
<p class="fs16 lh14">Creating a culture that encourages two things: constant experimentation, taking chances, and learning from failure; and a knowledge that mastery requires repetition and practise.</p>
<p class="fs16 lh14">Experimentation and taking risks are what keeps us pushing forward, even if it means venturing deeper into the danger zone than we've ever gone before. We also require mastery of the talents that will allow us to retreat from the danger zone after we have gone too far.</p>
<p class="fs16 lh14">Allocating time for daily work development, building rituals that reward the team for taking chances, and injecting defects into the system to increase resilience are all results of the Third Way.</p>
<h2 class="fs28 cb mdtp15 lh15 mlh14"><strong>Incremental Releases</strong></h2>
<p class="fs16 lh14">Teams had to wait their time to deploy code before DevOps. Bottlenecks, sometimes known as merge hell, were frequently created by a delay in code release. Errors and incompatibilities are unavoidable when developers are forced to wait a long time to contribute work.</p>
<p class="fs16 lh14"><strong>DevOps</strong> encourages engineers to contribute new code as frequently as possible, typically many times each day. A single project is divided into small, manageable portions in a DevOps environment, and teams submit code in increments. This makes troubleshooting bad code before it is published to production much easier. DevOps teams produce code updates and bug fixes on a daily, weekly, or monthly basis, depending on the process.</p>
<p class="fs16 lh14">The development and deployment cycle is more flexible with incremental releases. As a result, teams can react fast to unexpected changes and quickly correct faults and defects. The main goal is to keep poor code out of the hands of the end-user.</p>
<h2 class="fs28 cb mdtp15 lh15 mlh14"><strong>Automation</strong></h2>
<p class="fs16 lh14">Automating as much of the software development process as feasible is one of DevOps' most important principles. Developers can concentrate completely on creating code and building new features by automating procedures.</p>
<p class="fs16 lh14">In a <strong>DevOps</strong> environment, anything that can be automated should be automated. Compiling the source code to see if it will function in production is as simple as running a single command.</p>
<p class="fs16 lh14"><strong>DevOps</strong> teams can run automated tests to see if the new code is production-ready if the application is written in a language that doesn't require compilation. Automation will generate an alert if there are any faults or flaws in the code, letting developers know which lines of code are creating problems.</p>
<h2 class="fs28 cb mdtp15 lh15 mlh14"><strong>DevOps Pipeline</strong></h2>
<p class="fs16 lh14"><strong>DevOps</strong> attempts to create a repeatable system, a loop that allows for development continuity. Pipelines are created by DevOps teams to do this.</p>
<p class="fs16 lh14">A pipeline is a repeatable system consisting of phases that code must travel through before being deployed to production. There are four main phases in a typical DevOps pipeline:</p>
<p class="fs16 lh14">First and first, the developers must write the code. Build the team then checks for faults by compiling the code into a build. Test Following the build step, operations teams test the new code to ensure that it behaves as expected in the production environment. Deploy the updated code is delivered to the end-user after it has passed the testing phase.</p>
<h2 class="fs28 cb mdtp15 lh15 mlh14"><strong>Continuous Integration</strong></h2>
<p class="fs16 lh14">In a <strong>DevOps</strong> workflow, Continuous Integration (CI) is critical. It encourages developers to submit code to a central code repository on a daily basis.</p>
<p class="fs16 lh14">The likelihood of faulty code going down the pipeline and causing service outages is considerably decreased by merging smaller portions of code on a frequent basis. DevOps approaches are used by some of the world's largest companies, which commit new code hundreds of times every day.</p>
<p class="fs16 lh14">Automated testing is another important part of Continuous Integration. Developers make builds of the project before committing their code to the master branch to ensure that the new code is compatible with the current code. Developers will submit their code to the common repository if the build is successful.</p>
<h2 class="fs28 cb mdtp15 lh15 mlh14"><strong>Continuous Delivery</strong></h2>
<p class="fs16 lh14">Continuous Delivery (CD) is all about quickly and regularly releasing code updates. Unlike Continuous Deployment, which uses an automated approach to code release, CD relies on developers to manually push code to production. It's critical to establish a repeatable system for pushing code through the DevOps pipeline if CD is to be successful.</p>
<p class="fs16 lh14">In a CD environment, developers must bear in mind that their code contributions could be deployed to production at any time. Code updates can be released to production with a single click after passing all tests and reviews.</p>
<p class="fs16 lh14">Continuous supply has numerous advantages. Because code changes are usually minimal, it avoids the danger of downtime and other performance issues. Second, CD makes it easier for businesses to release high-quality features, resulting in a faster time-to-market and the elimination of fixed deployment expenses.</p>
<h2 class="fs28 cb mdtp15 lh15 mlh14"><strong>Continuous Monitoring</strong></h2>
<p class="fs16 lh14">Continuous Monitoring is based on the CI/CD concepts and ensures that the application runs well. Monitoring technologies and approaches are used by DevOps teams to keep track of how the application is performing.</p>
<p class="fs16 lh14">Logs, apps, systems, and infrastructure are all monitored by DevOps teams. DevOps teams can instantly return the app to a previous state whenever a problem is discovered. During this time, the team focuses on correcting known issues without informing the user that the code is being updated on a regular basis.</p>
<p class="fs16 lh14">Continuous monitoring also aids DevOps teams in detecting issues that are impeding pipeline productivity. Teams should improve the CI/CD pipeline after each release cycle to reduce bottlenecks and enable a smooth flow of code from one step to the next.</p>
<h2 class="fs28 cb mdtp15 lh15 mlh14"><strong>Feedback Sharing</strong></h2>
<p class="fs16 lh14">Feedback is essential in <strong>DevOps.</strong> Developers want actionable data from a variety of sources in order to improve the overall quality of the programme. DevOps teams can waste time producing products that don't add value to stakeholders or customers if they don't get feedback.</p>
<p class="fs16 lh14">Before, during, and after the release cycle, DevOps teams typically obtain input from stakeholders, end-users, and software-based monitoring systems. They get input using a variety of methods, including social media and surveys, as well as discussions with co-workers.</p>
<p class="fs16 lh14">Teams must have systems in place to help them sort through the feedback they've received and extract the most useful data. The feedback that is misleading or false can be harmful to the entire development process.</p>
<h2 class="fs28 cb mdtp15 lh15 mlh14"><strong>Version Control</strong></h2>
<p class="fs16 lh14">Every successful <strong>DevOps</strong> workflow starts with version control, commonly known as source control. It aids DevOps teams in being organised, focused, and informed about what their members are upon. Version control is also essential for ensuring that teams interact more quickly and effectively in order to support frequent product releases.</p>
<p class="fs16 lh14">Version control, in a nutshell, is a central code repository where developers contribute code and track changes throughout the development process. Team members can create branches of the primary project in most version control systems. Individual developers can work on branches of a project's source code without altering the original version.</p>
<h2 class="fs28 cb mdtp15 lh15 mlh14">Conclusion</h2>
<p class="fs16 lh14">I've gone over how the <strong>DevOps</strong> concept came to be and why it's so important. DevOps is a culture and technique that brings together development, testing, and operations to ensure that software is delivered in a timely, high-quality, and efficient manner. The key concepts enable collaboration and integration between development and IT operations, as well as automation and incremental delivery where possible. It also implies being adaptable to changes in order to maintain continual improvement and monitoring. Its main goal is to ensure that development and operations are in sync for a smoother and faster delivery.</p>

what is a principle of DevOps, there are certain rules and regulations for DevOps to be implemented and to be followed, so this blog describes all the important principles of DevOps to be followed.

What is a Principle of Devops

<h2 class="fs16 lh14  mdtp15 lh15 mlh14">WHAT IS SELENIUM TESTING</h2>
<p class="fs16 lh14">Selenium is a web testing tool that runs tests directly in a browser using simple scripts. "It automates browsers," to put it simply. It is a portable web application software testing platform that includes a record/playback tool for designing tests without having to learn a test scripting language (Selenium IDE).</p>
<p class="fs16 lh14">It also includes a test domain-specific language that can be used to build tests in C#, Java, Groovy, Perl, PHP, Python, and Ruby, among other popular programming languages. Selenium is available for Windows, Linux, and Macintosh computers.</p>
<p class="fs16 lh14">Selenium is a strong test automation framework. It's been around since 2004, therefore it's a well-established system. Selenium employs test scripts to ensure that your user interface is functional. The script merely lists the commands that should be run on the user interface. The Selenium architecture is depicted in the diagram below.</p>
<p class="fs16 lh14">The Selenium server receives the test script. To interact with the proper Web Driver, JSON is used. The Web Driver then sends the command to the browser, which executes it and provides the result.</p>
<h2 class="fs16 lh14  mdtp15 lh15 mlh14">WHAT IS FUNCTIONAL TESTING</h2>
<p class="fs16 lh14">Testing a software application against business requirements to ensure that all functionalities work as intended is known as functional testing. Because users are now vertically centered, functional testing is carried out from the user's perspective to ensure maximum coverage and reduce the possibility of problems.</p>
<p class="fs16 lh14">Black box testing is a type of functional testing in which quality assurance specialists focus solely on software functionality and do not test the internal code structure. This style of testing focuses solely on software requirements and specifications, ignoring the system's structure and just testing module operation and behavior. Any software must go through functional testing to ensure that it is ready for deployment.</p>
<p class="fs16 lh14">Functional testing entails ensuring that your software performs as intended. It's a broad term that refers to a variety of topics. However, from the standpoint of user interface design, it has a more precise meaning. Smoke testing, integration testing, and regression testing are common examples. Because the complexity of today's user interfaces necessitates automating your testing, here's a quick primer on Selenium functional testing.</p>
<p class="fs16 lh14">The purpose of functional testing is to guarantee that the web application's performance meets the functional requirements or specifications. You test all of the functions of a web application to ensure that the web application meets the requirements.</p>
<p class="fs16 lh14">It uses black box testing approaches and has nothing to do with the application's source code. The User Interface, Database, APIs, Client/Server connection, Security, and other tiny components are all tested during functional testing.</p>
<p class="fs16 lh14">Functional testing can be done both manually and automatically. You test the functioning of a web application via functional testing. These tests include evaluating the web application's primary functionality as well as verifying basic usability by ensuring that users can browse the online application without difficulty. You must also ensure that the appropriate error messages appear if an error circumstance arises.</p>
<h2 class="fs16 lh14">TYPES OF FUNCTIONAL TESTING</h2>
<h3 class="fs16 lh14">UNIT TESTING</h3>
<p class="fs16 lh14">It is usually carried out by developers (who write the application's unit codes) to accomplish specialized functionality for each unit. During unit testing, each component of the web application is checked to ensure that it functions properly.</p>
<p class="fs16 lh14">Unit tests supplement functional testing by identifying the components that could cause a failure. It is always preferable to detect flaws as early as possible in the process, as diagnosing failed tests as a whole becomes more difficult. Unit tests are one of the most common types of automated functional testing, as developers frequently write them to ensure that the various units are bug-free. Early testing promotes a faster turnaround time and higher quality.</p>
<h3 class="fs16 lh14  mdtp15 lh15 mlh14">SMOKE TESTING</h3>
<p class="fs16 lh14">Any new release of the program undergoes smoke testing to confirm that the web application's basic functionality is operational. The most critical components and functionality of the program are covered during smoke testing.</p>
<p class="fs16 lh14">The goal is to ensure that an application's important feature is operational.</p>
<p class="fs16 lh14">Only if the web application passes the smoke test is it regarded as stable and dependable. Once it's stable, testers can undertake functional testing on the new features before moving on to regression testing depending on the scenario.</p>
<p class="fs16 lh14">If the smoke testing fails, it indicates that the current release isn't stable and has to be addressed.</p>
<h3 class="fs16 lh14  mdtp15 lh15 mlh14">REGRESSION TESTING</h3>
<p class="fs16 lh14">When new code, enhancements, or features are added to a web app, regression testing guarantees that the program's functionality is not harmed. Regression testing's main goal is to detect flaws that may have crept into an existing build after new features or functions were added.</p>
<p class="fs16 lh14">Let's imagine you're working with a visitor management system, and the most recent release has a new feature that provides a report of all visitors based on the category they fit into. After you've completed the smoke testing for this release, you'll need to run regression testing to check that the code from the previous version doesn't introduce any new bugs.</p>
<p class="fs16 lh14">Regression testing can be time-consuming and demanding for testers because they are required to undertake it every time a new feature is added to the program. By switching to Selenium test automation, you can quickly solve this problem. With the help of Selenium Grid, you can not only automate your repetitious tests but can also scale them to expand your test coverage.</p>
<h3 class="fs16 lh14  mdtp15 lh15 mlh14">SANITY TESTING</h3>
<p class="fs16 lh14">Sanity testing confirms that the changes in the new build have resolved the issues without introducing any new bugs. Most testers get sanity and smoke testing mixed up since they sound so similar.</p>
<p class="fs16 lh14">However, there isn't much of a difference between the two tests. Sanity testing is used to evaluate new functions of a web app, whereas smoke testing is used to verify the end-to-end functionality of a web app.</p>
<h3 class="fs16 lh14  mdtp15 lh15 mlh14">INTEGRATION TESTING</h3>
<p class="fs16 lh14">Integration testing ensures that when an application's modules are combined, they work properly and do not include any problems.</p>
<p class="fs16 lh14">Integration tests allow operational commands and data to work together as a whole system rather than as separate components. It's usually used to discover problems with user interface activities, operational timing, API calls, data formats, and database access.</p>
<h3 class="fs16 lh14  mdtp15 lh15 mlh14">SYSTEM TESTING                                             </h3>
<p class="fs16 lh14">System testing is the process of checking a full, integrated application to see if it meets the requirements. It is carried out following the completion of integration testing. It is also not accomplished by testers who are involved in the development of the program; rather, it is accomplished by individual testers.</p>
<p class="fs16 lh14">It's an important aspect of functional testing because it determines whether or not the application fits the operational, practical, and business criteria.</p>
<h3 class="fs16 lh14">CROSS-BROWSER TESTING</h3>
<p class="fs16 lh14">When your app is ready to go live, you might assume that it would work the same way on all platforms. However, this isn't always the case because each browser's rendering engine produces a web app differently.</p>
<h2 class="fs16 lh14  mdtp15 lh15 mlh14">ADVANTAGES OF AUTOMATED FUNCTIONAL TESTING</h2>
<p class="fs16 lh14">It has a number of advantages for developers, including the ability to provide a high-quality product that fulfills end-user needs while guaranteeing that they are satisfied with the end results. Produces a bug-free software product while assuring that all of the application's features are operational. Enhances the application's overall security and safety. Reduces the chance of losing money on the web app/software product.</p>
