description ResiliencyHub Overview
AWS Resilience Hub is a cloud service from Amazon Web Services that enables developers to define, validate, and track the resilience of their applications running on AWS infrastructure. Introduced in 2021, the platform assesses applications against defined disruption scenarios to identify weaknesses before they cause outages. It provides actionable recommendations and integrates with other AWS tools to help engineering teams maintain operational reliability and minimize downtime.
help ResiliencyHub FAQ
What do RTO and RPO mean inside AWS Resilience Hub?
RTO is the target time for recovering an application, while RPO is the acceptable amount of data loss measured in time. Resilience Hub tests whether the AWS architecture can meet those targets for application, infrastructure, Availability Zone, and Region disruptions.
Does AWS Resilience Hub automatically fail over my application during an outage?
No, Resilience Hub primarily assesses the application and recommends resilience improvements rather than acting as an automatic disaster-recovery switch. Its recommendations can include alarms, Standard Operating Procedures, and AWS Fault Injection Simulator tests.
What does a Resilience Hub assessment actually produce?
An assessment compares application components with a resilience policy and reports compliance, estimated recovery targets, and a resilience score. AWS documentation also describes recommendations for alarms, SOPs, and recovery testing after each application version changes.
