When designing AWS workloads to be operational even when there are component failures, what is an AWS best practice?
Perform quarterly disaster recovery tests.
Place the main component on the us-east-1 Region.
Design for automatic failover to healthy resources.
Design workloads to fit on a single Amazon EC2 instance.
Explanations:
While performing disaster recovery tests is important, it does not ensure operational continuity on its own.
Placing a component in a single region (like us-east-1) does not address resilience across multiple regions.
Designing for automatic failover to healthy resources aligns with AWS best practices for high availability.
Relying on a single EC2 instance introduces a single point of failure, reducing workload resilience.
I evaluate that the answer is:
Design for automatic failover to healthy resources.
I would say the answer is:
Design for automatic failover to healthy resources.
