SAA-C03 - Design Resilient Architectures - Section 2.7
Design fault-tolerant compute and storage using load balancer health checks, redundancy and durable storage.
Describe how Elastic Load Balancing health checks detect unhealthy targets and automatically redirect traffic to healthy instances, and explain why stateless application design simplifies horizontal scaling and fault tolerance. Recognise that Amazon S3 is designed for 99.999999999% durability through redundant storage across multiple devices, and use EBS snapshots to provide point-in-time recovery for block storage volumes.
