What is DevOps? DevOps lifecycle explained

In the fast-paced world of software development, efficiency and collaboration are paramount. Enter DevOps is a methodology that has revolutionized how software is built, tested, and deployed. But what exactly is DevOps, and how does it work? In this comprehensive guide, we’ll delve into the heart of DevOps, unraveling its principles, practices, and the life cycle that drives its success. Whether you’re a seasoned IT professional or just dipping your toes into the world of software development, understanding DevOps is essential for staying ahead in today’s tech landscape. So, let’s embark on this journey to demystify DevOps and explore the intricacies of its lifecycle.

A DevOps team embodies a collaborative approach, blending the expertise of developers and IT operations throughout the product lifecycle to enhance the velocity and excellence of software deployment. It marks a paradigm shift, a cultural evolution that profoundly impacts both teams and the organizations they serve.

In DevOps, the traditional separation between development and operations teams dissolves. These entities often fuse into a unified team, wherein engineers engage across the entire application lifecycle, spanning development, testing, deployment, and operations, equipped with diverse multidisciplinary skills.

Empowered by a suite of tools designed to automate and expedite processes, DevOps teams elevate reliability. A DevOps toolchain becomes instrumental in addressing core DevOps tenets such as continuous integration, continuous delivery, automation, and collaborative workflows. The ethos of DevOps extends beyond development alone, permeating into adjacent domains such as security. When security teams embrace the DevOps ethos, security becomes an intrinsic and proactive element of the development process, giving rise to what is known as DevSecOps.

A DevOps certification course offers a structured pathway to understand DevOps and its lifecycle comprehensively. Participants gain proficiency in key DevOps principles, practices, and tools through curated curriculum and hands-on training. This immersive learning experience equips individuals with the knowledge and skills to effectively navigate each stage of the DevOps lifecycle, from development and testing to deployment and operations. Ultimately, DevOps certification empowers learners to drive organizational efficiency, collaboration, and innovation in software development processes.

What is DevOps?

DevOps is a collaborative methodology that bridges the gap between software development (Dev) and IT operations (Ops), aiming to streamline and automate the software delivery process. It emphasizes continuous integration, delivery, and deployment, fostering a culture of collaboration, communication, and shared responsibility among cross-functional teams. DevOps promotes using tools and practices to automate manual tasks, improve efficiency, and enhance the quality of software releases. By breaking down silos and promoting transparency, DevOps enables organizations to deliver high-quality software rapidly, reliably, and at scale, thus accelerating innovation and enhancing customer satisfaction.

DevOps Lifecycle

Due to DevOps’ continuous nature, practitioners utilize the infinity loop to illustrate the interconnectedness of the DevOps lifecycle phases. Although it may seem sequential, the loop signifies the imperative for ongoing collaboration and iterative enhancement across the entire lifecycle.

Discover: In the discovery phase, teams identify and understand the needs and objectives of the given project. This involves gathering customer needs, market trends, and business goals. Key activities include conducting market research, gathering user feedback, and aligning the project goals with the overall business strategy. The goal is to ensure that the development efforts are focused on delivering value to the customers and meeting business objectives.

Plan: The planning phase involves creating a roadmap for the project, defining tasks, setting timelines, and allocating resources. Teams establish priorities, define milestones, and develop a clear plan of action to guide the development process. Collaboration among team members is crucial during this phase to ensure alignment and accountability.

Build: In the build phase, developers write code to implement the features and functionality outlined in the project plan. This phase involves coding, code review, and integration of code changes into the main codebase. Continuous integration practices are often employed to automate the process of building and testing code changes as they are committed.

Test: Testing is a critical phase where the quality and functionality of the software are evaluated. The different types of testing, such as integration testing, unit testing, and system testing, are performed to identify and fix defects. Automated testing tools and frameworks are commonly used to streamline the test process and ensure thorough test coverage.

Deploy: Deployment involves releasing the software to the production environment for end-users to access and use. This phase includes configuring servers, deploying application code, and ensuring that the software is ready for production use.

Automation tools and deployment pipelines are often used to streamline and automate the deployment process, reducing the risk of errors and downtime.

Operate: Once the software is deployed, the operation phase begins, where the focus shifts to monitoring and managing the software in production.

Operations teams are responsible for ensuring the availability, performance, and security of the software. Continuous monitoring and alerting systems are used to detect and respond to issues in real time, minimizing downtime and disruptions.

Observe: The observation phase involves gathering feedback and data from the production environment to inform future development efforts.

Teams monitor key performance indicators, user behavior, and system metrics to identify the areas of improvement and optimization.

This phase emphasizes the importance of data-driven decision-making and continuous improvement.

Continuous Feedback: Continuous feedback is a fundamental aspect of the DevOps lifecycle, facilitating collaboration and iteration throughout the entire process. Feedback loops are established between different lifecycle phases, allowing teams to learn from each iteration and adjust as needed. Feedback can come from various sources, including end-users, stakeholders, automated testing tools, and monitoring systems. By incorporating feedback into the development process, teams can continuously improve the software’s quality, performance, and user experience.


DevOps embodies a transformative approach to software development, collaboration, fostering automation, and continuous improvement throughout the lifecycle. Understanding the intricacies of the DevOps lifecycle is essential for organizations striving to enhance efficiency, quality, and innovation in their software delivery processes. A DevOps certification course offers a structured pathway to master the DevOps lifecycle, providing comprehensive knowledge and practical skills to navigate each phase effectively. Through hands-on training and curated curriculum, participants gain proficiency in continuous integration, delivery, deployment, and feedback loops, empowering them to drive organizational success in today’s dynamic tech lands
