Proposed and deployed a production AWS environment for PT Synapsis Sinergi Digital in the ap-southeast-1 (Singapore) region, with a deliberate focus on cost optimization through ARM-based compute.
Compute Strategy
Instead of x86 EC2 instances, the cluster runs on EC2 Graviton (ARM) nodes. ARM-based instances deliver comparable or better performance at lower cost for containerized workloads, making them a strong fit for a cost-conscious production setup.
Kubernetes on EKS
Amazon EKS manages the control plane, eliminating the overhead of maintaining a self-managed Kubernetes control plane in the cloud. Node groups use Graviton instances with auto-scaling policies tuned to workload demand.
Database
Amazon RDS for PostgreSQL provides managed relational storage with automated backups, multi-AZ for production reliability, and parameter groups tuned for the application's query patterns.
Storage
Amazon S3 serves as object storage for application assets, build artifacts, and backups.
Outcome
The ARM-first approach reduced EC2 compute costs noticeably compared to equivalent x86 instance types, while performance metrics remained within acceptable production thresholds validated through k6 load testing.
