DevOps
CI/CD
Continuous Integration builds and tests every push so problems surface early; Continuous Delivery/Deployment automates releasing that tested code to production. Together they shrink feedback loops and make deploys frequent and boring. The investment is a reliable pipeline and a solid test suite — flaky tests quietly erode trust in the whole thing.
Purpose
Continuous Integration builds and tests every push automatically, so breakage surfaces in minutes rather than at release time. Continuous Delivery/Deployment extends the pipeline to ship that verified code — to a staging environment on every merge, or straight to production. The goal is to make releasing frequent and boring.
When to Use It
Every team benefits: the pipeline is the gatekeeper that runs tests, linting and builds on each pull request, and the release mechanism that deploys on merge. It also encodes the deploy procedure itself — no more tribal knowledge about 'the release steps'.
Trade-offs
The pipeline is only as trustworthy as its tests: flaky tests train the team to ignore red, at which point the safety net is gone. Slow pipelines throttle everyone, so build time is a feature. Full continuous deployment also demands solid monitoring and fast rollback.
Implementation
Define the pipeline as code in the repo (e.g. GitHub Actions): install, lint, test, build on every push; deploy on merge to main. Cache dependencies for speed, run jobs in parallel, keep secrets in the platform's secret store, and make the deploy step idempotent with an obvious rollback path.
