Infrastructure as Code Improvements

Current State

• Basic EKS cluster setup with VPC
• Manual configuration aspects may exist
• Limited automation in infrastructure deployment

Proposed Improvements

1. Terraform Modularization:

   • Create reusable modules for VPC components
   • Separate modules for EKS cluster and node groups
   • Implement remote state management
   • Add variable validation

2. Infrastructure Versioning:

   • Implement proper state locking
   • Add workspace management
   • Version control for infrastructure changes
   • Backup and disaster recovery setup

3. Security Enhancements:

   • Implement AWS KMS encryption
   • Add proper IAM roles and policies
   • Network security groups optimization
   • Enable VPC flow logs

4. Monitoring & Logging:

   • CloudWatch integration
   • Prometheus & Grafana setup
   • Implement proper alerting
   • Add audit logging

Implementation Steps:

1. Refactor existing Terraform code into modules
2. Implement state management improvements
3. Add security enhancements
4. Set up monitoring and logging
5. Document all changes and create runbooks
