"When I started deploying my apps to the cloud, I realized how many manual steps it took to get the app running. That's when I discovered CI/CD and GitOps tools that automate everything from testing to deployment, so developers can focus on writing code instead of wasting time on manually deploying each time. In this article, I'll break down what CI/CD and GitOps mean, why they matter, and how they simplify deploying microservices."
"Understanding Microservices Deployment Challenges - Why deploying microservices is harder than monolithic apps and how automation helps. Understanding CI/CD Pipeline- Breaking down Continuous Integration (testing, building) and Continuous Deployment (delivery to production). Understanding GitOps- How Git acts as a single source of truth for deployments, and how tools like Argo CD and Flux implement it. Open Ecosystem Approach - Using GitHub Actions for CI and Argo CD for CD on Amazon EKS."
Microservices introduce operational complexity through distributed components, independent lifecycles, networking, and complex deployments. Continuous Integration automates testing and building, while Continuous Deployment automates delivery to environments and production. GitOps treats Git as the single source of truth for desired cluster state and uses controllers like Argo CD or Flux to reconcile deployments. A common open-ecosystem pattern uses GitHub Actions for CI and Argo CD for CD on Amazon EKS; alternatives include Jenkins, CircleCI, and AWS CodeBuild/CodePipeline. Automating pipelines minimizes manual steps, speeds releases, improves reliability and safety, and enables scalable, repeatable deployments across microservices.
