Availability Zones
B
Regions
Explanation:
The principle "design for failure and nothing will fail" emphasizes building resilient systems that can handle component failures gracefully. AWS services that support this principle include:
-
Availability Zones (A): These are physically separate data centers within an AWS Region that provide fault isolation and high availability. By distributing resources across multiple Availability Zones, you can ensure your system remains operational even if one zone fails.
-
Regions (B): AWS Regions are geographic areas that contain multiple Availability Zones. Using multiple Regions allows for disaster recovery and global redundancy, further enhancing system resilience.
Both Availability Zones and Regions are fundamental to building fault-tolerant architectures on AWS, aligning with the design for failure principle.
