Question

A company runs a Linux app on Amazon EKS usingM6i EC2 instances under a Savings Plan that is about to expire. They want to reduce costsafter expiration. Which combination of steps should a solutions architect take to meet these requirements? (Choose three)

Accepted Answer

The question asks how to **reduce costs** after a Savings Plan expires. The key insight is that **AWS Graviton (ARM64) instances are ~20% cheaper** than comparable x86_64 instances while delivering equal or better performance. Here's how each step works together:

**A. Rebuild containers for ARM64 architecture:**
Containers compiled for x86_64 won't run natively on ARM64 processors. You must rebuild your container images targeting the ARM64 (aarch64) architecture. Since the app runs on Linux, ARM64 compatibility is generally straightforward — most Linux software compiles cleanly for ARM. You can use multi-arch Docker builds (`docker buildx`) to create images that work on both architectures.

**C. Migrate EKS nodes to Graviton instances (e.g., C7g, M7g):**
