Infrastructure as code transformed our deployment reliability. Manual server configuration was error-prone and undocumented. With IaC, every change is version-controlled, peer-reviewed, and reproducible across environments.
Key Considerations
Testing strategy evolved significantly over the project lifecycle. We started with heavy unit test coverage but gradually shifted toward integration and end-to-end tests that provided higher confidence with less maintenance overhead.
Let’s walk through a practical example. Suppose you have an existing application that needs to handle increasing traffic while maintaining sub-second response times across all endpoints.
Key Considerations
Documentation is often the first thing to be neglected and the last thing to be updated. We adopted a docs-as-code approach where documentation lives alongside the codebase and goes through the same review process as any other change.
If you found this guide helpful, consider sharing it with your team. The practices described here work best when adopted collectively rather than individually.
