The Challenge

The client’s legacy infrastructure faced limitations impacting reliability, scalability, and operational efficiency. Manual application deployments on EC2 instances caused slow deployments and inconsistent environments. The MariaDB RDS setup created overhead with fragmented schemas and no automated disaster recovery. Without containerization, the platform struggled to scale and adopt modern DevOps practices. Non-centralized CI/CD processes resulted in deployments without proper rollbacks, quality checks, or automation. Inconsistent, non-modular Terraform usage increased maintenance efforts. Limited observability due to absent centralized logging, metrics, tracing, and alerting, plus lack of structured secret management and DevSecOps integrations, created security and monitoring gaps.

Solutions

• Established Shared Services OU with secure networking, centralized CI/CD, and DevSecOps tools.
• Designed reusable Terraform modules for Amazon EKS, Amazon Aurora, Amazon VPC with Terragrunt and Atlantis automation.
• Containerized legacy applications, deployed to Amazon EKS with Karpenter autoscaling and Helm charts.
• Deployed Kafka/Redis on Amazon EKS for Dev/Staging, MSK/ElastiCache for Production with secret management.
• Built Jenkins, integrated Bitbucket, configured ArgoCD GitOps, blue-green rollouts, and observability stack.

The Results

Improved scalability, reliability, and performance by 80% with Amazon EKS and Amazon Aurora, reduced deployment time by 60-70% through CI/CD and GitOps, cut costs by 35-45% with autoscaling, achieved 90% better visibility with centralized monitoring, enhanced security with managed services, and established future-ready platform reducing deployment timeline from weeks to less than a day.
