AWS EKS Production Infrastructure (ARM / Graviton)

Production-grade AWS infrastructure in the Singapore region using EKS with ARM-based EC2 Graviton instances, RDS/PostgreSQL, and S3 — optimized for cost-to-performance ratio.

Published

October 1, 2023

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.
