Years ago, software delivery followed a predictable but painful pattern—developers would build an application, toss it over to QA, and then operations would struggle to deploy it without breaking production. Bugs piled up, releases got delayed, and finger-pointing became a norm.
Then came DevOps, and everything changed.
At Bacancy, we’ve helped teams accelerate releases, improve software quality, and create rock-solid pipelines that minimize failures. But DevOps isn’t just about using Jenkins or Kubernetes—it’s about adopting a mindset of continuous improvement, collaboration, and automation.
To get it right, you need to master the DevOps lifecycle—not just as a theoretical framework but as a practical approach that enables engineering teams to build, test, and deploy software seamlessly.
Let’s dive into what the DevOps lifecycle actually is and explore the key phases of DevOps Lifecycle in detail.
What is the DevOps Lifecycle?
The DevOps lifecycle is at the core of the DevOps approach. It’s a structured process that covers everything from planning and development to deployment and continuous monitoring. The ultimate goal is to help teams deliver high-quality software faster, with more reliability, and with fewer hurdles.
What sets the DevOps lifecycle apart from traditional models is its emphasis on collaboration. Instead of operating in silos, development and operations teams align to work together, forming a partnership. This alignment ensures smooth handoffs, quicker releases, and a more efficient workflow.
The lifecycle works with an iterative approach, which means there’s a constant loop of feedback and improvement. Each phase builds upon the other, creating a seamless flow that promotes agility and innovation.
Now, let me walk you through each phase of the DevOps Lifecycle and share how it all fits together.
Understanding the 8 Key Phases of DevOps Lifecycle
Here’s a detailed overview of the eight essential phases of DevOps lifecycle that work together for seamless delivery.
1. Plan: Aligning Engineering with Business Goals
This is where most teams go wrong. Developers love to jump straight into coding, but without a clear roadmap, they end up building features no one needs. I’ve seen projects derail simply because engineering teams weren’t aligned with business objectives.
At Bacancy, before writing a single line of code, we make sure of three things:
✔️ We understand the problem we’re solving—why does this feature matter?
✔️ We align with business priorities—are we focusing on impact, not just output?
✔️ We break work into achievable sprints—small, incremental releases always win.
We use Jira and Confluence to track everything, but tools are secondary. The real game-changer? Engineering, product, and business teams working together from day one.
2. Code: Writing Maintainable, Secure Code from the Start
Writing code is the easy part—writing good code that scales is the real challenge. I’ve seen junior developers ship features in record time, only for senior engineers to spend weeks cleaning up the mess.
At Bacancy, we enforce:
✔️ Code reviews (peer-to-peer feedback is a lifesaver).
✔️ Git workflows (feature branching, proper commit messages).
✔️ Shift-left security (catch vulnerabilities early instead of patching later).
A small tip? Don’t let ego get in the way of refactoring. The best developers I’ve worked with are the ones who aren’t afraid to rewrite code for the sake of long-term stability.
3. Build: Automating the Integration Process
One of the biggest pain points in traditional software development was "It works on my machine" syndrome. A developer’s code would run fine locally but fail in the shared repo.
That’s why Continuous Integration (CI) exists. Every commit triggers an automated build, ensuring everything integrates smoothly.
We use:
✔️ Jenkins & GitHub Actions to automate builds.
✔️ Docker to create consistent environments.
✔️ Artifact repositories like JFrog to store versioned builds.
Here’s what I always tell my teams:
“If your build isn’t automated, you don’t have a DevOps pipeline. You have a manual mess.”
4. Test: Catching Bugs Before They Reach Users
In my early days, I once worked on a project where QA found 200+ defects just before release. It was a nightmare—devs scrambled to fix bugs, the product launch was delayed, and customers were frustrated. Lesson learned: testing is not optional.
At Bacancy, we take a layered approach to testing:
✔️ Unit tests (JUnit, Mocha) to validate small pieces of code.
✔️ Integration tests (Postman, SoapUI) to check API functionality.
✔️ Performance tests (JMeter) to handle scalability.
✔️ Security tests (SonarQube) to prevent vulnerabilities.
Golden rule: If you’re not automating tests, you’re inviting trouble. The longer a bug survives in the pipeline, the more expensive it becomes to fix.
5. Release: Deploying Without Disrupting Users
Releasing new software versions shouldn’t feel like defusing a bomb. But without proper release strategies, I’ve seen teams push updates that crashed production, leaving businesses scrambling for damage control.
At Bacancy, we follow:
✔️ Blue-green deployments (roll out updates gradually, not all at once).
✔️ Feature flags (enable/disable features without redeploying).
✔️ Automated rollbacks (if something fails, revert instantly).
Here’s a simple truth:
“If your release process is risky, you’re doing it wrong.”
6. Deploy: Delivering at Scale, Without Failures
Deployments used to be an anxiety-inducing process. But today, with Infrastructure-as-Code (IaC) and automation, deployments are fast, repeatable, and reliable.
At Bacancy, we use:
✔️ Terraform & Ansible to define infrastructure in code.
✔️ Kubernetes to manage containerized apps.
✔️ CI/CD pipelines to deploy with a single click.
One thing I always emphasize? Automate rollbacks. No matter how confident you are, assume that something will break—and have a quick way to revert.
7. Operate: Keeping Systems Stable and Secure
Software isn’t "done" once deployed—that’s when the real work begins. If your system goes down at 3 AM, you need proactive monitoring to fix issues before users even notice.
Key tools we use:
✔️ Prometheus & Grafana (monitor performance).
✔️ ELK Stack (analyze logs for troubleshooting).
✔️ Datadog & New Relic (track real-time user experience).
Here’s the truth:
“If you’re reacting to outages instead of preventing them, you don’t have a DevOps culture. You have firefighting.”
8. Monitor: Using Data to Drive Continuous Improvement
The final step? Learn from every deployment.
We monitor:
✔️ Application performance metrics (response times, errors).
✔️ User behavior data (how real people interact with the software).
✔️ Security logs (detect and mitigate threats).
This phase closes the DevOps loop—every deployment feeds back into the planning phase, making future releases smarter, faster, and more reliable.
Conclusion
The phases of DevOps lifecycle represent more than just a workflow—they embody a culture of collaboration, innovation, and operational excellence. Each phase is essential in helping organizations deliver top-quality software with speed and reliability.
At Bacancy, we’ve seen how mastering each phase of the DevOps lifecycle can transform not just software delivery but entire business operations. Ready to enhance your DevOps practices? Our DevOps Consulting Services are here to guide you through every phase with confidence.
