The DevOps lifecycle is the framework that underpins this transformation establishing the intersection of agile, automation, and cross-functional collaboration to speed delivery while still delivering quality.
- Understanding the DevOps Lifecycle
The DevOps lifecycle represents a continuous process of software progression from idea to user value – represented as an infinity loop to signify that it is iterative (and continuous). The increasing popularity of DevOps methodologies are simply based on a process breakdown consisting up to seven to eight phases:
Plan → Code → Build → Test → Release → Deploy → Operate → Monitor → Feedback/Iterate.
- Exploring the Core Phases
Here’s a deeper dive into each phase, enriched with tool examples and best practices:
1. Defines the vision by unifying stakeholders, backlog creation, and alignment with business goals—typically via platforms like Jira, Trello, and Azure DevOps Boards | |
2. Developers write code, manage changes, and collaborate using Git-based systems such as GitHub, GitLab, or Bitbucket. | |
3. Code is compiled or packaged into artifacts—like container images or binaries—using tools such as Jenkins, Maven, or Gradle. | |
4. Automated testing (unit, integration, security) ensures quality. Tools include Selenium, JUnit, SonarQube, supported by CI pipelines | |
5. After approval, software is prepared for deployment using CI/CD tools (e.g., ArgoCD, GitLab CI/CD, Terraform), aiming for automation and consistency. | |
6. Ensures ongoing performance and maintenance, using Infrastructure as Code (IaC) and config tools like Ansible, Puppet, Terraform. | |
7. Tracks system health and user behavior via tools such as Prometheus, Grafana, ELK Stack, Datadog. Insights fuel iterations and planning for subsequent cycles. |
- Best Practices That Elevate the Lifecycle
- Automation is Non-Negotiable: CI/CD pipelines and IaC eliminate manual steps, reduce errors and support consistency and speed.
- Collaborative Culture: Bridging Dev and Ops through shared ownership accelerates our work and controls quality.
- Utilize Continuous Feedback Loops: Monitoring and feedback shape future development and close the loop in the lifecycle.
- Integrate Toolchains Wisely: Tools need to flow appropriately and continuously across stages- a break here slows delivery and reduces quality.
- Fusion Institute’s Emphasis
Fusion Institute emphasizes the DevOps lifecycle as the central framework for agile and effective IT operations. While their outline mirrors the standard seven-phase model, they add value through their academic lens—integrating theory, practical training, and real-world tools to ready students for industry demands.
Fusion Institute's take aligns well with these principles, offering a grounded framework that bridges classroom understanding with real-world readiness.
