A Detailed Overview"},"content":{"rendered":"<p><span style=\"font-weight: 400;\">Technology moves too fast for teams to stay in their own lanes. Developers build something, hand it off, and operations teams struggle to keep it running. Sound familiar? That wall between \u201cDev\u201d and \u201cOps\u201d is exactly what DevOps was created to tear down.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">At its core, DevOps is about people, not just processes. It\u2019s a way of working that helps development and operations teams build, test, and deliver software faster and more reliably by working as one. Instead of chasing deadlines in silos, DevOps brings shared responsibility, smarter automation, and constant feedback into every release cycle.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Think of it as the next step after Agile, where speed meets stability, and collaboration replaces coordination. The result? Teams release better software, customers see improvements sooner, and organizations keep evolving without losing momentum.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In this guide, we\u2019ll break down what DevOps means, how it works in practice, the principles that drive it, and the tools and lifecycle stages that make it one of the most transformative IT methodologies.<\/span><\/p>\n<p><iframe title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/4I2uOZw3moM\" width=\"560\" height=\"315\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><\/iframe><\/p>\n<h2><b>What is DevOps?<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">DevOps is a culture that emphasizes improved collaboration, communication, and integration between development and operations teams.

DevOps quickly removes existing barriers between the two and promotes cohesive, seamless organizational functioning. DevOps principles not only improve software development and operations performance but also positively impact web service development and quality assurance.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Furthermore, DevOps lays the groundwork for a culture of knowledge and information sharing among the IT team, bridging communication gaps and facilitating the establishment and continuous delivery.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">There is evidence from many globally-renowned research firms that DevOps has grown continuously since its inception and will continue to do so in the future!<\/span><span style=\"font-weight: 400;\">\u00a0 As a result, DevOps is arguably the most influential trend in software development today. This is reflected in the fact that DevOps engineer is one of the most in-demand IT roles. For example, over 17,000 DevOps engineer jobs are listed on Indeed.com in the USA, with an average salary ranging from $96,600 to $122,000.<\/span><\/p>\n<h2><b>History of DevOps<\/b><\/h2>\n<p><strong>Patrick Debois, known as \u201cthe father of DevOps,\u201d coined the word \u201cDevOps\u201d in 2009<\/strong><span style=\"font-weight: 400;\">. DevOps is a branch of agile software development that grew out of the need to keep up with the speed at which software is built with Agile methods. Progress in agile culture and practices over the last decade revealed the need for a more holistic way to the end-to-end software delivery lifecycle. As a result, DevOps overcame the drawbacks of the Waterfall and Agile models. That\u2019s right! These were the two popular models used for software development before DevOps.<\/span><\/p>\n<h3><b>Waterfall Model<\/b><\/h3>\n<p><img class=\"aligncenter wp-image-20546\" src=\"https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/Agile-waterfall-model-devops-300x207.png\" alt=\"Waterfall Model\" width=\"600\" height=\"414\" srcset=\"https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/Agile-waterfall-model-devops-300x207.png 300w, https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/Agile-waterfall-model-devops-768x530.png 768w, https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/Agile-waterfall-model-devops-218x150.png 218w, https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/Agile-waterfall-model-devops-696x480.png 696w, https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/Agile-waterfall-model-devops-609x420.png 609w, https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/Agile-waterfall-model-devops-100x70.png 100w, https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/Agile-waterfall-model-devops.png 976w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/><\/p>\n<p><span style=\"font-weight: 400;\">The waterfall model uses a sequential approach to building any software.

Because of this, manual work is kept to a minimum. Parallel workflows, acceleration tools, scalable infrastructure, continuous integration servers, and other things also help make sure that development and deployment are done quickly and effectively.<\/span><\/p>\n<h3><b>Better Customer Satisfaction and Experience<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">The primary reason for implementing DevOps in business is to provide high-quality services to customers or end-users more quickly. Driving benefits around excellent customer experience and increased revenue is the best way to stay ahead of the competition. Many factors contribute to agility and efficiency, but deepening customer engagement is what matters at the end of the day.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Customers today expect a better experience across all digital platforms and brand touchpoints. Issues can be identified earlier in the development pipeline by focusing on collaboration between different teams and introducing multiple feedback loops. As a result, time spent troubleshooting is reduced, and the customer experience improves.<\/span><\/p>\n<h3><b>Wider Reliability<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Development, deployment, and other processes become more dependable and error-free. The team can quickly identify any inconsistencies or problems in the program thanks to DevOps and continuous testing, which ensure faster development cycles. Because of good communication and experience sharing, it is simple to address issues quickly. It&#8217;s also very easy to undo a deployment at any time.<\/span><\/p>\n<p><img class=\"aligncenter wp-image-20555\" src=\"https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/Benefits-of-Implementing-DevOps-300x163.png\" alt=\"Benefits of Implementing DevOps \" width=\"600\" height=\"326\" srcset=\"https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/Benefits-of-Implementing-DevOps-300x163.png 300w, https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/Benefits-of-Implementing-DevOps-1024x556.png 1024w, https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/Benefits-of-Implementing-DevOps-768x417.png 768w, https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/Benefits-of-Implementing-DevOps-696x378.png 696w, https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/Benefits-of-Implementing-DevOps-1068x580.png 1068w, https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/Benefits-of-Implementing-DevOps-774x420.png 774w, https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/Benefits-of-Implementing-DevOps.png 1395w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/><\/p>\n<h3><b>Increased Data ROI<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">One key aspect is the financial benefits of DevOps. It makes it easy for businesses to turn data into money quickly. A business that is automated and flexible can also help people see the value of data. Businesses save time and money when DevOps utilities run Big Data tools. It is possible to quickly recoup costs and reduce response time by a huge amount, increasing profitability.<\/span><\/p>\n<h3><b>Reduced Time to Market<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">One of the primary reasons <\/span><span style=\"font-weight: 400;\">DevOps is important for your business is that it allows you to deliver software more quickly due to streamlined processes, proper automation and systematic release planning<\/span><span style=\"font-weight: 400;\">. A shorter time to market means you have a better chance of outrunning your competitors.<\/span><\/p>\n<h3><b>Reduced Deployment Failures and a Shorter Recovery Time<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Programming errors cause the majority of development failures. As a result, having a DevOps team will enable more releases in shorter spawns. This makes finding potential bugs in the code easier and more likely. For the same reason, and if a problem does arise, recovery will be accelerated due to the knowledge and participation of all members throughout the development process.<\/span><\/p>\n<h2><b>What are DevOps Principles?<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">With a DevOps culture, developers get closer to the user because they better understand their requirements and needs. Operations teams participate in the development process and add customer needs and maintenance requirements. It means following the following key principles, which help DevOps teams deliver applications and services faster and better than organizations that use the traditional software development model.<\/span><\/p>\n<h3><b>Establish a Collaborative Environment<\/b><\/h3>\n<p><img class=\"aligncenter\" src=\"https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/team-300x300.png\" alt=\"Collaborative Environment\" width=\"90\" height=\"90\" \/>D<span style=\"font-weight: 400;\">evOps brings together development and operations teams, implying a collaborative environment, a unified team pursuing common goals. As a result, teams are encouraged to communicate, brainstorm, share ideas, and solve problems. Also, this collaboration needs to start at the top and work its way down, starting with support from the executives.<\/span><\/p>\n<h3><b>Automation<\/b><\/h3>\n<p><img class=\"wp-image-20565 aligncenter\" src=\"https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/automation-300x300.png\" alt=\"Automation\" width=\"90\" height=\"90\" srcset=\"https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/automation-300x300.png 300w, https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/automation-150x150.png 150w, https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/automation-420x420.png 420w, https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/automation.png 512w\" sizes=\"(max-width: 90px) 100vw, 90px\" \/><\/p>\n<p><span style=\"font-weight: 400;\">DevOps requires automating as much of the software development lifecycle as possible. This provides developers with more time to write code and create new features. Automation is an important component of a CI\/CD pipeline because it reduces human errors and increases team productivity. Teams can achieve continuous improvement with short iteration times when they use automated processes, allowing them to respond quickly to customer feedback.<\/span><\/p>\n<p><b>NOTE: <\/b><span style=\"font-weight: 400;\">The process of delivering software is made easier by a CI\/CD pipeline. It helps you build code, run tests, and safely release a new software version.

Shared Responsibility<\/strong><\/h3>\n<p><span style=\"font-weight: 400;\">In a DevOps model, development, operations, testing, and even security teams work as one cross-functional unit. Everyone shares ownership of the product\u2019s quality, uptime, and performance. This eliminates the \u201cit\u2019s not my problem\u201d mindset that often slows teams down.<\/span><\/p>\n<h3><strong>2. Automation at Every Step<\/strong><\/h3>\n<p><span style=\"font-weight: 400;\">Automation keeps the pipeline moving smoothly. Tasks such as code integration, testing, and deployment are handled by tools like Jenkins, GitLab CI\/CD, or CircleCI. This not only speeds up delivery but also ensures each release is consistent and error-free.<\/span><\/p>\n<h3><strong>3. Continuous Integration and Delivery (CI\/CD)<\/strong><\/h3>\n<p><span style=\"font-weight: 400;\">The CI\/CD pipeline is where DevOps really shines. Developers continuously merge code into a shared repository, and automated tests verify it right away. When it passes, the code is packaged and deployed automatically to staging or production environments, often multiple times a day.<\/span><\/p>\n<h3><strong>4. Integrated Security &#8211; DevSecOps<\/strong><\/h3>\n<p><span style=\"font-weight: 400;\">Modern DevOps brings security into every stage, creating what\u2019s known as DevSecOps. Instead of testing security at the end, teams build it into the development process through automated scans, policy checks, and secure coding practices.<\/span><\/p>\n<h3><strong>5. Monitoring and Feedback<\/strong><\/h3>\n<p><span style=\"font-weight: 400;\">Once deployed, the software is continuously monitored using tools like Prometheus, Datadog, or Splunk. Real-time performance data and customer feedback help teams identify bottlenecks and release improvements faster.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">DevOps works because it turns software delivery into a living system, one where automation, collaboration, and feedback keep the cycle running continuously and intelligently.<\/span><\/p>\n<h2><b>DevOps Lifecycle<\/b><\/h2>\n<p><img class=\"wp-image-20573 aligncenter\" src=\"https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/Devops-life-cycle-300x200.png\" alt=\"DevOps Lifecycle\" width=\"600\" height=\"400\" srcset=\"https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/Devops-life-cycle-300x200.png 300w, https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/Devops-life-cycle-768x512.png 768w, https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/Devops-life-cycle-696x464.png 696w, https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/Devops-life-cycle-630x420.png 630w, https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/Devops-life-cycle.png 996w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/><\/p>\n<p><span style=\"font-weight: 400;\">The DevOps lifecycle is a set of automated development processes or workflows within an iterative development lifecycle. It includes continuous software development, integration, testing, deployment, and monitoring phases. The DevOps strategy promotes continuous innovation, agility, and scalability to create, test, consume, and evolve software products. It encourages experimentation, feedback, and continuous learning to improve goods, services, and processes. Developers must be completely aware of all steps of the DevOps lifecycle to produce faster outcomes. Let&#8217;s take a quick look at how the DevOps lifecycle works at each stage.<\/span><\/p>\n<h3><b>Plan<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">At this stage, teams identify business requirements and gather feedback from end users. They develop a project roadmap to maximize business value and deliver the apt product during this stage.<\/span><\/p>\n<h3><b>Code<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">The code development takes place during this stage. To avoid security flaws and poor coding practices, development teams use tools and plugins such as Git to streamline the development process.<\/span><\/p>\n<h3><b>Build<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Once developers finish their tasks, they use tools like Maven and Gradle to add the code to the shared code repository.<\/span><\/p>\n<h3><b>Test<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Once the build is complete, it is deployed to the test environment to perform various types of testing, such as user acceptance testing, security testing, integration testing, performance testing, and so on, using tools such as JUnit, Selenium, and so on, to ensure software quality.<\/span><\/p>\n<h3><b>Release<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">In this stage, the build is ready to be used in the production environment. Once the build passes all the tests, the operations team schedules the releases or sends multiple releases to production, depending on what the organization needs.<\/span><\/p>\n<h3><b>Deploy<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">At this stage, Infrastructure-as-Code assists in creating the production environment and then releases the build using various tools.<\/span><\/p>\n<h3><b>Operate<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">The release is now available for customers to use. At this stage, the operations team is in charge of server configuration and provisioning via tools such as Chef.<\/span><\/p>\n<h3><b>Monitor<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">At this stage, the DevOps pipeline is monitored using data gathered from customer behavior, application performance, and other sources. Monitoring the entire environment assists teams in identifying bottlenecks affecting the productivity of the development and operations teams.<\/span><\/p>\n<h2><b>Phases of DevOps Lifecycle<\/b><\/h2>\n<p><img class=\"wp-image-20574 aligncenter\" src=\"https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/Phases-of-devops-lifecycle-300x123.png\" alt=\"Phases of DevOps Lifecycle\" width=\"600\" height=\"246\" srcset=\"https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/Phases-of-devops-lifecycle-300x123.png 300w, https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/Phases-of-devops-lifecycle-1024x420.png 1024w, https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/Phases-of-devops-lifecycle-768x315.png 768w, https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/Phases-of-devops-lifecycle-696x286.png 696w, https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/Phases-of-devops-lifecycle-1068x438.png 1068w, https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/Phases-of-devops-lifecycle.png 1321w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/><\/p>\n<p><span style=\"font-weight: 400;\">Everything in DevOps, from strategy to maintenance, is ongoing, as we previously stated. Let us now divide the entire lifespan into seven stages, with stability as the focal point. Every phase of the DevOps lifecycle can be repeated several times throughout the program until it is completed. The goal is to create an environment where code can move quickly while maintaining high-quality levels.<\/span><\/p>\n<h3><b>Continuous Development<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Continuous development involves both software planning and coding. Here, the entire development process is divided into smaller development cycles. This procedure facilitates the DevOps team&#8217;s ability to accelerate the overall software development process. Furthermore, this phase is instrumental in mapping the vision for the development cycle, enabling developers to comprehend project expectations fully. As a result, the team begins to visualize its ultimate goal.<\/span><\/p>\n<h3><b>Continuous Integration<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Continuous integration is the most important stage of the DevOps lifecycle. During this phase, updated code or add-on functionalities and features are developed and integrated into existing code. Furthermore, bugs in the code are detected and identified during this phase at each step through unit testing, and the source code is modified accordingly. This step transforms integration into a continuous process in which code is tested at each commit. Furthermore, the necessary tests are planned during this phase.<\/span><\/p>\n<h3><b>Continuous Testing<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">During the testing phases of the DevOps process, the DevOps team checks for bugs, errors, configuration, UX\/UI issues, and other issues. <\/span><span style=\"font-weight: 400;\">Software testing is classified into components like unit testing and system integration testing<\/span><span style=\"font-weight: 400;\">.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">QA teams test to ensure that all software components function as your DevOps team and end users intend. The best continuous testing tools for automating the phase include Selenium, Ranorex, Test.ai, TestSigma, TestNG, and JUnit. The software code is ready for production after passing this phase. If this is not the case, a good CI tool (Continuous Integration Tool) will usually notify the programmer who iterated the code to fix the problem (regression automation).<\/span><\/p>\n<h3><b>Continuous Deployment<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">This is the most important and active phase of the DevOps lifecycle, in which the final code is deployed on production servers. The continuous deployment includes configuration management to ensure that code is deployed accurately and smoothly on servers. Development teams deploy code to servers and schedule server updates, ensuring that configurations remain consistent throughout the production process. Containerization tools also aid deployment by ensuring consistency between development, testing, production, and staging environments. This practice allowed for the continuous delivery of new characteristics in production.<\/span><\/p>\n<h3><b>Continuous Monitoring<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">During this phase, the application&#8217;s functionality and attributes are continuously monitored to detect system errors such as low memory, a non-reachable server, etc. This procedure helps the IT team quickly identify app performance issues and their underlying cause. If IT teams discover a critical issue, the application is re-run through the DevOps cycle to find a solution. During this phase, however, security issues can be detected and resolved automatically.<\/span><\/p>\n<h3><b>Continuous Feedback<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">All stakeholders provide feedback to help improve the product during the continuous feedback DevOps phase. The DevOps methodology differs from traditional software development methodologies in that it involves many stakeholders, including the client, product team, development, cloud operations, finance, and management.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The phase collects data from software running and being monitored in live production with real users. Continuous feedback is provided, and all parties actively discuss ways to improve the product.<\/span><\/p>\n<h3><b>Continuous Operations<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">The last stage of the DevOps lifecycle is the shortest and most straightforward. Continuity, on the other hand, is at the heart of all DevOps operations that help automate release processes, allowing developers to detect issues faster and build better software product versions. Furthermore, persistence is essential for eliminating diversions and other extra steps that impede development.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Continuous operations have shorter development cycles, allowing organizations to advertise constantly and reduce the overall time to market the product. Moreover, DevOps makes software products more valuable by making them better and more efficient, attracting new customers.<\/span><\/p>\n<h2><b>DevOps Tools<\/b><\/h2>\n<p><img class=\"aligncenter wp-image-20575\" src=\"https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/Devops-tools-300x212.png\" alt=\"DevOps Tools\" width=\"600\" height=\"424\" srcset=\"https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/Devops-tools-300x212.png 300w, https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/Devops-tools-768x543.png 768w, https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/Devops-tools-696x492.png 696w, https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/Devops-tools-594x420.png 594w, https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/Devops-tools-100x70.png 100w, https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/Devops-tools.png 981w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/><\/p>\n<p><span style=\"font-weight: 400;\">DevOps tools assist businesses in solving some of the <a href=\"https:\/\/www.invensislearning.com\/blog\/devops-adoption-challenges-and-solution\/\" target=\"_blank\" rel=\"noopener\">challenges<\/a> associated with implementing DevOps practices.

The challenge of fostering a DevOps culture necessitates significant changes in how people work and collaborate. However, when organizations commit to a DevOps culture, they can foster the development of high-performing teams.<\/span><\/p>\n<h3><b>Collaboration, Transparency, and Alignment<\/b><\/h3>\n<p><img class=\"wp-image-20579 aligncenter\" src=\"https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/partners-300x300.png\" alt=\"Collaboration\" width=\"100\" height=\"100\" srcset=\"https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/partners-300x300.png 300w, https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/partners-150x150.png 150w, https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/partners-420x420.png 420w, https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/partners.png 512w\" sizes=\"(max-width: 100px) 100vw, 100px\" \/><\/p>\n<p><span style=\"font-weight: 400;\">Collaboration between teams, which begins with visibility, is one of the hallmarks of a healthy DevOps culture. Different teams, such as development and IT operations, must share their DevOps processes, priorities, and concerns. These teams must also plan their work together and agree on business goals and success measures.<\/span><\/p>\n<h3><b>Shifts in Scope and Accountability<\/b><\/h3>\n<p><img class=\"wp-image-20580 aligncenter\" src=\"https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/standard-300x300.png\" alt=\"Shifts in Scope and Accountability\" width=\"100\" height=\"100\" srcset=\"https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/standard-300x300.png 300w, https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/standard-150x150.png 150w, https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/standard-420x420.png 420w, https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/standard.png 512w\" sizes=\"(max-width: 100px) 100vw, 100px\" \/><\/p>\n<p><span style=\"font-weight: 400;\">As teams become more aligned, they take ownership and become involved in lifecycle phases other than the ones central to their roles. Developers, for example, are held accountable for the innovation and quality established during the development phase, as well as the performance and stability their changes bring during the operation phase. Simultaneously, IT managers must ensure that governance, security, and compliance are included in the planning and development phases.<\/span><\/p>\n<h3><b>Shorter Release Cycles<\/b><\/h3>\n<p><img class=\"wp-image-20581 aligncenter\" src=\"https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/release-300x300.png\" alt=\"Shorter Release Cycles\" width=\"100\" height=\"100\" srcset=\"https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/release-300x300.png 300w, https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/release-150x150.png 150w, https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/release-420x420.png 420w, https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2020\/07\/release.png 512w\" sizes=\"(max-width: 100px) 100vw, 100px\" \/><\/p>\n<p><span style=\"font-weight: 400;\">By releasing software in short cycles, DevOps teams remain agile.

This is in addition to setting up a DevOps culture. These practices aid in accelerating, automating, and improving a specific phase. Others span multiple phases, assisting teams in creating seamless processes that boost productivity.<\/span><\/p>\n<h3><b>Continuous Integration and Continuous Delivery<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Since the inception of DevOps, there has been a great deal of interest in the CI\/CD pipeline, which is the foundation of the concept. In a nutshell, continuous integration is a DevOps-style practice in which software developers regularly merge source code into a centralized repository. The CI pipeline will initiate build and test operations on every repository merge.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The continuous delivery pipeline typically allows teams to deploy software releases on test, stage, or production environments as soon as the CI pipeline produces a successful build. This also enables developers and quality assurance engineers to perform extensive testing and upgrades, identifying flaws or concerns ahead of time.<\/span><\/p>\n<h3><b>Agile Software Development<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Agile is a software development method that emphasizes teamwork, customer and user feedback, and high adaptability to change via short release cycles. The Agile teams provide continuous changes and improvements to customers, collect feedback, and then learn and adjust based on customer requirements and needs. As a result, agile differs significantly from traditional frameworks, such as waterfall, which features lengthy release cycles defined by sequential phases. Kanban and Scrum are two well-known Agile frameworks.<\/span><\/p>\n<h3><b>Infrastructure as Code<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Infrastructure as code is a way of setting up and managing infrastructure using code and software development techniques, like version control and continuous integration. The API-driven model of the cloud lets developers and system administrators interact with infrastructure programmatically and at scale instead of setting up and configuring resources by hand. So, engineers can use code-based tools to talk to infrastructure and treat infrastructure the same way they treat application code. Infrastructure and servers can also be set up quickly using standard patterns, updated with the updated patches and versions, or duplicated in ways that can be done repeatedly.<\/span><\/p>\n<h3><b>Shift Left with CI\/CD<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">When teams &#8220;shift left,&#8221; they incorporate testing into their code development processes as early as possible. Rather than sending various changes to a separate test or QA team, various tests are carried out throughout the coding process to allow developers to fix bugs or improve code quality. They are both working on the relevant section of the codebase at the same time. The ability to shift left is based on continuous integration, continuous delivery, and deployment, or CI\/CD and deployment.<\/span><\/p>\n<h3><b>Monitor the DevOps Pipeline and Applications<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">It&#8217;s critical to keep an eye on the DevOps pipeline so that a broken build or failed test doesn&#8217;t cause unnecessary delays. For example, automation accelerates development, but if an automated process fails and no one knows, you&#8217;re better off doing the work manually. Similarly, it is critical to monitor production applications to detect failures or performance deficiencies before your customers do.<\/span><\/p>\n<h2><b>Case Studies of DevOps<\/b><\/h2>\n<h3><b>1.
