9 DevOps Best Practices: What You Should Do and Not Do

What is DevOps and Why It Matters?

DevOps is a set of best practices around the software development lifecycle that aim to continuously improve and deliver value more efficiently. It represents a culture of shared responsibility between developers and operations, enabling faster, higher‑quality software delivery through collaboration, automation, observability, and feedback.

Followable DevOps Best Practices

Below are nine practical practices that help teams adopt a healthy DevOps culture.

1. Foster a Culture of Collaboration and Blameless Communication

Encourage an environment where people can collaborate freely without fear of failure, building trust and empathy. Break down silos, align teams toward common goals, and involve security and compliance teams early in workflow approvals.

2. Adopt Continuous Integration and Delivery (CI/CD)

Integrate small batches of code frequently into a central repository, allowing early error detection and higher code quality through automated builds and tests. Follow up with continuous delivery to keep code in a deployable state, automating the push to production.

3. Implement Automated Testing

Integrate meaningful automated tests—unit, integration, end‑to‑end, load, smoke—into the CI/CD pipeline to catch defects early and reduce manual testing effort.

4. Focus on Observability and the Right Metrics

Track key DevOps metrics such as deployment time, frequency, failure rate, service availability, mean time to detection, mean time to recovery, cost per change, code coverage, and lead time. Establish strategies for logging, tracing, and metrics to quickly diagnose issues.

5. Use Automation to Eliminate Manual Work

Automate repetitive tasks to increase consistency, reduce human error, and free teams to focus on higher‑value work.

6. Embed Security Early (DevSecOps)

Integrate security considerations from the start of the development lifecycle, making security a shared responsibility and part of the CI/CD pipeline to protect the software supply chain.

7. Learn from Incidents and Build Processes Around Them

Conduct post‑incident reviews, document findings, and continuously improve processes to reduce future incidents.

8. Prioritize Concepts Before Tools

Understand core DevOps concepts first, then select tools that address missing capabilities, avoiding tool sprawl.

9. Adopt Infrastructure as Code (IaC) and Enable Self‑Service Infrastructure

Treat cloud infrastructure as code, version‑controlled and auditable, enabling developers to provision resources through automated pipelines, increasing productivity and reducing bottlenecks.

DevOps Anti‑Patterns

Common pitfalls include creating a separate DevOps team, relying on DevOps heroes, attempting to automate everything at once, chasing shiny new tools, sacrificing quality for speed, neglecting continuous improvement, and ignoring documentation and information sharing.

By applying the practices above and avoiding the anti‑patterns, teams can accelerate performance and value creation.
