Deployments happen on Fridays because \"someone needs to watch it over the weekend.\" Rollbacks mean reverting a commit and redeploying, which takes 45 minutes and involves three people. Your team deploys once every two weeks because deployments are risky and painful — which makes each deployment riskier because it bundles more changes.\u003c\/p\u003e\n\n\u003cp\u003eThis blueprint documents the CI\/CD platform I built for an enterprise SaaS company deploying 47 microservices an average of 23 times per day with zero-downtime rolling deployments, automated canary analysis, and one-click rollback in under 90 seconds.\u003c\/p\u003e\n\n\u003ch3\u003eWhat You Get\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eArchitecture diagrams\u003c\/strong\u003e — Pipeline topology from commit through build, test, security scan, staging deploy, canary analysis, and production promotion (Draw.io)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerraform modules\u003c\/strong\u003e — CodePipeline with CodeBuild stages, ECR repository with lifecycle policies, ECS rolling deployment configuration, CodeDeploy with canary traffic shifting, and artifact encryption with KMS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipeline definitions\u003c\/strong\u003e — \u003ccode\u003ebuildspec.yml\u003c\/code\u003e templates for build, unit test, integration test, SAST scan (\u003ccode\u003esemgrep\u003c\/code\u003e), container image scan (\u003ccode\u003etrivy\u003c\/code\u003e), and deployment stages\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRollback automation\u003c\/strong\u003e — CloudWatch alarm-triggered automatic rollback, manual one-click rollback procedure, and database migration rollback patterns\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eKey Architecture Decisions\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCanary deployments over blue-green for microservices\u003c\/strong\u003e — Blue-green doubles infrastructure cost during deployment. Canary shifts 5% of traffic to the new version, monitors error rates and latency for 10 minutes, then progressively shifts to 25%, 50%, and 100%. If any metric breaches the threshold, traffic shifts back to the previous version automatically.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrunk-based development over GitFlow\u003c\/strong\u003e — Long-lived feature branches create merge conflicts and delay integration feedback. Trunk-based development with feature flags means every commit is deployable, integration issues surface within hours not weeks, and you can release features independently from deployments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecurity scanning in the pipeline, not after deployment\u003c\/strong\u003e — \u003ccode\u003esemgrep\u003c\/code\u003e for SAST and \u003ccode\u003etrivy\u003c\/code\u003e for container vulnerability scanning run as build stages. A critical vulnerability blocks the pipeline before the image is pushed to ECR. Shifting security left means vulnerabilities never reach production rather than being discovered by a monthly scan.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArgoCD for Kubernetes, CodeDeploy for ECS\u003c\/strong\u003e — If you run EKS, ArgoCD provides GitOps-based deployment with drift detection and self-healing. For ECS workloads, CodeDeploy's native canary and linear deployment strategies integrate with ALB target groups without additional tooling. The blueprint covers both paths.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWho This Blueprint Is For\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDevOps Engineers building their first automated deployment pipeline beyond manual deploys\u003c\/li\u003e\n\u003cli\u003ePlatform teams creating a standardized deployment platform for multiple product teams\u003c\/li\u003e\n\u003cli\u003eEngineering Managers who want to increase deployment frequency while reducing deployment risk\u003c\/li\u003e\n\u003cli\u003eSREs who need automated rollback capabilities tied to production health metrics\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eYour First 48 Hours\u003c\/h3\u003e\n\u003cp\u003eDeploy the CodePipeline + CodeBuild + ECR Terraform modules into a sandbox account. Push the included sample application (a Go HTTP service) to trigger the pipeline. Watch it build, run tests, scan for vulnerabilities, push to ECR, and deploy to an ECS service. On day two, introduce a deliberate bug (an endpoint that returns 500 errors), push it, and watch the canary deployment detect the elevated error rate and automatically roll back. This demonstrates the full deployment safety net end-to-end.\u003c\/p\u003e\n\n\u003ch3\u003eLimitations and Trade-offs\u003c\/h3\u003e\n\u003cp\u003eCanary analysis requires sufficient traffic volume — at fewer than 100 requests per minute to the canary, statistical significance takes too long and you should use a time-based linear deployment instead. CodePipeline has a limit of 50 pipelines per region (expandable via support request). Database schema migrations require careful coordination with rolling deployments — the blueprint includes a pattern for backward-compatible migrations but does not cover all edge cases (column renames, table splits). ArgoCD adds cluster-level operational overhead — evaluate whether your team can maintain it before adopting GitOps.\u003c\/p\u003e","brand":"Citadel Cloud Management","offers":[{"title":"Default Title","offer_id":54890408509731,"sku":"CCM-ARC-026","price":39.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0979\/8539\/7027\/files\/citadel-devops-product_69b56879-d053-491a-9c8a-613af863b541.png?v=1775137878","url":"https:\/\/www.citadelcloudmanagement.com\/products\/ci-cd-pipeline-architecture-for-enterprises","provider":"Citadel Cloud Management","version":"1.0","type":"link"}
