Amazon Introduces AWS Resilience Hub to Monitor and Improve RPO and RTO

This item in japanese


Amazon recently announced the availability of AWS Resilience Hub, a service designed to help customers define, measure, and manage the resilience of their applications on the cloud.

The service lets users define Recovery Time Objective (RTO) and Recovery Point Objective (RPO) objectives and evaluates the configuration to ensure it meets the requirements. There are four steps involved when working with Resilience Hub to reduce the time to recover from a failure and the time in which data might be lost after an incident: add the application to assess, define the resilience policy, run an assessment and apply any of the recommendations.

Following the AWS Well-Architected Framework best practices, AWS Resilience Hub can discover applications deployed by AWS CloudFormation, including cross regions and cross account stacks. Sébastien Stormacq, principal developer advocate, explains how to achieve continuous resilience validation:

Resilience Hub also provides APIs for development teams to integrate their resilience assessment and testing into their CI/CD pipelines for ongoing resilience validation. Integrating resilience validation into CI/CD pipelines helps ensure that every change to the application’s underlying infrastructure does not compromise its resilience.

Stormacq adds:

AWS Resilience Hub lets you define your RTO and RPO objectives for each of your applications. Then it assesses your application’s configuration to ensure it meets your requirements. It provides actionable recommendations and a resilience score to help you track your application’s resiliency progress over time.


In a separate article, Seth Eliot, principal reliability solutions architect at AWS, explains how to build resilient well-architected workloads using AWS Resilience Hub, showing examples of actionable recommendations:

If I switch from MySQL RDS to Amazon Aurora I can use backtracking to reduce the 1 hour 40 minute RTO that it takes to restore an RDS database backup.

Max Winter, senior solutions architect at AWS, adds:

This is awesome! Much better than building your resilience estimates on a spreadsheet and hoping you remembered to copy every service’s SLA correctly!

AWS Resilience Hub is currently available in a limited number of AWS regions, including North Virginia and Ireland. Mike Charle, architect at BOX Processing, comments:

Not supported in any region we use. Not even in London.

Customers are charged based on the number of applications described in Resilience Hub, starting at $15 USD per application per month. There is a free tier for the first six months, up to three applications.
