"While building apps I learned that writing code is only half the journey - getting it deployed, updated, and running reliably is also just as important if not more. 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."
"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."
Deploying microservices requires coordinating builds, tests, containerization, and cluster updates, making manual processes error-prone and slow. Continuous Integration automates testing and building, while Continuous Deployment automates delivering artifacts to production environments. GitOps uses Git as the single source of truth for declarative cluster state and employs controllers like Argo CD or Flux to reconcile cluster state with Git. Open ecosystem tools such as GitHub Actions can handle CI while Argo CD manages CD on Amazon EKS. AWS services like CodeBuild and CodePipeline provide native alternatives. Automated pipelines reduce manual steps, improve safety, and scale deployments.
