SAA-C03 - Design High-Performing Architectures - Section 3.4

Improve performance through load distribution and scaling using Elastic Load Balancing, Auto Scaling and placement groups.

Describe how Elastic Load Balancing spreads traffic across healthy targets and integrates with Auto Scaling to add or remove capacity in response to demand. Compare EC2 placement group strategies - cluster for low-latency HPC, spread for fault isolation, and partition for large distributed systems - and explain how connection draining allows in-flight requests to complete before an instance is deregistered.
