AWS wellarchitected documentation change
Summary
Updated terminology from 'Regional' to 'Region' service. Added five new bullet points on agent reliability best practices and replaced the failure management section with expanded content comparing on-premises vs. cloud reliability.
Security assessment
The changes focus on general reliability improvements and architectural best practices. The agent-related additions discuss failover mechanisms, decision consistency, recovery procedures, testing frameworks, and observability—all standard reliability engineering concepts without security context. The failure management update compares cloud vs. on-premises durability without referencing vulnerabilities or security incidents.

[Failure management](https://docs.aws.amazon.com/wellarchitected/latest/reliability-pillar/failure-management.html): Failures are a given, and everything eventually fails over time. This is a given, whether you are using the highest-quality hardware or lowest cost components. _“Everything fails all the time. We needed to build systems that embrace failure as a natural occurrence.”_ — Werner Vogels + 4. [Failure management](https://docs.aws.amazon.com/wellarchitected/latest/reliability-pillar/failure-management.html): While on-premises data centers face daily hardware component failures, cloud services like Amazon EBS and Amazon S3 are designed to provide built-in protection with high levels of availability and durability. Despite these robust protections, implementing additional resiliency measures remains essential for reliable workloads, requiring teams to be thoroughly trained on business objectives and reliability requirements to effectively design, implement, and operate mission-critical systems.
