These stats are enough to highlight the importance of DevOps in modern software development practices.

Yet, the question remains—what exactly is the DevOps Lifecycle? Let’s keep exploring its various phases, which help achieve the end goal of continuous delivery and quality improvement.

What is the DevOps Lifecycle?

The DevOps Lifecycle is a process consisting of numerous stages of software development and deployment, all while fostering collaboration between development and operations teams. The lifecycle aims to deliver faster and more efficient software by ensuring continuous integration, testing, deployment, and monitoring processes. With evolving technologies and adopting automation and close collaboration, DevOps practices guarantee that customer demands are met faster and that high software development quality is maintained.

Definition and Purpose of the DevOps Lifecycle

At its core, the DevOps Development Lifecycle manages, maintains, and optimizes the end-to-end software development process, from planning to testing and from deployment to continuous monitoring. An efficient DevOps cycle aims to achieve higher standards of continuous delivery and bring about overall improvement by automating and streamlining the entire process.

Moreover, the ultimate goal of a lifecycle in DevOps is to bring together the development and operations teams by fostering an environment of continuous improvement, shared responsibility, and joint accountability for the quality of code and operational performance. It helps enhance communication, collaboration, and automation to achieve high-quality software, faster releases, and better business outcomes.

Core Principles Driving the DevOps Lifecycle

Several core principles help keep it going so that the DevOps cycle delivers results and drives success in the long term for the organization. These principles are:

1. 1. Collaboration: In DevOps, there are no silos between development and operation teams. Instead of developers and operations teams working in isolation, they work together from the start of the lifecycle. By taking shared responsibility seriously, code quality improves and speeds up your problem-solving.
2. 2. Automation: DevOps focuses heavily on automation. They automate repetitive tasks like testing, integration, and deployment so there’s less opportunity for error, which can increase productivity. It also has faster cycles and higher consistency.
3. 3. Continuous Integration (CI): Developers daily merge their code into a shared repository. Each change immediately triggers automated tests to find issues before deploying the product code. This prevents integration problems and speeds up development cycles.
4. 4. Continuous Delivery (CD): This principle tries to automate delivery code changes to production. Teams optimize the user experience by being able to quickly and frequently deploy updates, all the while addressing issues powering through quickly.
5. 5. Monitoring and Feedback: Continuous system monitoring over its entire lifecycle provides real-time feedback. Issues can be identified and fixed proactively, ensuring the software works as expected in production environments.

DevOps Lifecycle Phases

The DevOps Lifecycle is a coalescence of versatile phases. Each phase has a distinctive role in the lifecycle, from planning to production and deployment to beyond. All the phases are mutually dependent on each other and contain feedback loops to ensure continuous improvement and the ability to adapt to change quickly. Here is a detailed description of each phase:



1. Plan: Requirements Gathering and Project Planning

The first phase of the DevOps cycle that no one realizes is planning. It’s where the project goals are defined, prerequisites are gathered, and development and operations teams are aligned. In this phase, after agreeing on a common timeline and project objectives, we meet stakeholders from both sides to discuss the project scope.

Key activities include:

• Identifying user needs and business objectives.
• Defining feature requirements.
• Estimating timelines and resources.
• Aligning teams for collaboration.

Effective planning ensures the development process has a clear direction, setting the stage for a smoother workflow across subsequent phases.

2. Develop: Collaborative Coding and Version Control

Coding the application is the focus of the development phase. Developers collaborate to develop the specifications laid out during the planning phase.

Key activities include:

• Writing clean, efficient code.
• If using version control systems (e.g., Git) for changes, share the work.
• Implementing continuous integration (CI) practices ensures code is merged and tested regularly.
• Continuous integration (CI) implementation helps with regular merging and testing of the code.

Collaboration and version control mean all developers work on the same codebase, thus eliminating conflicts and shortening the development process.

3. Build: Compilation and Packaging of Code

After building the code, the build phase comes up, which compiles and packages the application into runnableware. This is crucial if the code you’re working on needs to be transformed into a deployable unit, such as a container or a binary file.

Key activities include:

• Compiling the source code into executable artifacts.
• Packaging the code into deployment-ready formats (e.g., Docker containers, binary files).
• Ensuring dependencies are correctly resolved.

This phase in the DevOps cycle ensures the produced code is ready for testing and deployment.

4. Test: Automated and Manual Testing for Quality Assurance

To validate that no errors or defects exist in the application you want to deploy, there must be a continuous run of tests in the DevOps life cycle. The phase called Quality Testing combines automated and manual testing to test the quality of the application.

Key activities include:

• Running unit, integration, and end-to-end tests to identify defects early.
• Using automated testing tools (e.g., Selenium, Jenkins) for continuous testing.
• Manually testing for edge cases and user experience.

Automated testing ensures that fewer bugs are discovered in a later stage, which can minimize the company’s expenses.

5. Release: Preparing the Application for Deployment

When you can thoroughly test your application, you’re ready for the release phase. In this phase, your tested application is prepared and ready to be deployed for production. The release phase checks that all the needed configurations are ready and that the code is prepared to deploy.

Key activities include:

• Finalizing configurations and deployment scripts.
• Packaging the release for deployment.
• Ensuring all security and compliance checks are met.

Effective release management ensures that deployment is smooth and reliable.

6. Deploy: Automating and Streamlining the Deployment Process

This is where the application is being moved into production. DevOps focuses on automating Deploy phase to decrease the probability of human error and quicken deployment.

Key activities include:

• Automation tooling (e.g., Kubernetes, Ansible, Docker) to deploy code into production environments and some simple pipelines.
• Continuous deployment (CD) pipelines for painless and frequent deployments.
• Ensuring the deployment process is repeatable and reliable.

Automation in the deployment phase ensures that updates can be pushed to production frequently and without disruption.

7. Operate: Monitoring and Maintaining the Application Post-Deployment

After deployment, the application enters the operating phase, which is continuously monitored and maintained to ensure smooth operation.

Key activities include:

• Monitoring application performance using tools like Prometheus or Nagios.
• Addressing performance issues and scaling the application based on user demand.
• Infrastructure is managed effectively using Infrastructure as Code (IaC).

This phase helps ensure the application remains stable, secure, and efficient after deployment.

8. Monitor: Collecting Feedback for Continuous Improvement

The monitoring phase of the DevOps cycle is the last phase, when continuous feedback is collected to identify areas for improvement. By monitoring, teams can tackle problems at the prevention stage and improve an app for potential iterations of the product.

Key activities include:

• Collecting end-user feedback through monitoring tools (e.g., New Relic, Grafana).
• Analyzing system performance and identifying areas for optimization.
• Feedback informs the required iterations in line with the application development process.

This feedback loop is complete now, so teams can rely on data to make decisions and improve the application for the next release.
