Automate Custom CI/CD Pipelines for Landing Zone Accelerator on AWS

This article explains how to extend AWS Landing Zone Accelerator with automated CI/CD pipelines for deploying infrastructure across multiple AWS accounts using CodePipeline, CodeBuild, and GitHub integration.

• Hub-and-spoke architecture centralizes CI/CD in SharedServices account for governance
• Supports both CloudFormation and Terraform deployments with automated validation
• Implements security scanning using cfn-lint, cfn-nag, tflint, and tfsec tools
• Cross-account IAM roles enable secure multi-account deployments with least-privilege access
• Manual approval gates maintain governance oversight before production changes
• Encrypted artifact storage using S3, KMS, and DynamoDB for Terraform state locking
• Three-stage deployment: Foundation resources, CloudFormation pipeline, Terraform pipeline
• Estimated monthly costs: $5-7 for small apps, $30-40 for production environments

This solution accelerates workload deployments while maintaining enterprise security, compliance, and governance controls across multi-account AWS environments.
