SAA-C03 - Design High-Performing Architectures - Section 3.3

Design high-performing and elastic compute by selecting EC2 instance types, AWS Lambda and container compute.

Describe the EC2 instance families - general purpose, compute optimised, memory optimised, storage optimised, and accelerated computing - and match each to workload characteristics such as high CPU-to-memory ratio or GPU requirements. Distinguish AWS Fargate serverless container execution from self-managed EC2-backed ECS clusters, and recognise when AWS Lambda eliminates instance management overhead for short-duration event-driven tasks.
