AWS Resilience Hub: Features, Advantages And How It Works

What is AWS Resilience Hub?

AWS Resilience Hub manages and improves AWS application resilience. With AWS Resilience Hub, you can set resilience goals, assess your resilience posture, and implement the AWS Well-Architected Framework’s recommendations. AWS Fault Injection Service experiments in it imitate application disruptions to help you understand dependencies and discover vulnerabilities.

All of the AWS services and resources you require to consistently improve your resilience posture are centralized in the AWS Resilience Hub. To offer suggestions and assist you in managing the resources of your applications, AWS Resilience Hub collaborates with other services.

How it works

You may manage and enhance the resilience posture of your AWS apps from a single location in the AWS Console called AWS Resilience Hub. With the help of AWS Resilience Hub, you can establish your resilience objectives, evaluate your resilience posture in relation to those objectives, and put the AWS Well-Architected Framework’s suggestions for improvement into practice.

AWS Fault Injection Service (AWS FIS) experiments, which replicate actual application disturbances to help you better understand dependencies and identify potential vulnerabilities, may also be created and executed within AWS Resilience Hub.

You can get all the tools and services you need to keep improving your resilience posture in one location with it.

Why Use AWS Resilience Hub?

You only pay for the resources you utilize with AWS Resilience Hub. There are no minimum fees or up-front expenses. The amount of applications you define in AWS Resilience Hub determines how much you are paid.

For the first three applications, you can test AWS Resilience Hub for free for six months. After that, each application costs $15 per month to use AWS Resilience Hub. After you complete the application’s initial resilience assessment in it, metering for that application starts. Metering will cease if this application is deleted.

Any AWS service that AWS Resilience Hub provides will cost you money. A logical collection of AWS resources that you wish to function as a single entity is called an application in AWS Resilience Hub. Three distinct approaches can be used to represent an application in AWS Resilience Hub:

  • Terraform state files, AWS CloudFormation Stacks, AWS Service Catalogue AppRegistry, and AWS Resource Groups are examples of resource collections. Resources from different regions and accounts are supported by each collection.
  • Amazon EKS is used to manage Kubernetes workloads.
  • applications that make advantage of Amazon EKS clusters and resource collections.

Features

Describe

You can define applications for Kubernetes workloads that are handled on Amazon EKS, or you can describe your applications as resource collections, such as CloudFormation stacks, Terraform state files, my Applications, or resource groups. Amazon EKS clusters and resource collections can also be used to describe applications.

Define

Specify your apps’ resilience policies. RTO and RPO targets for infrastructure, applications, Availability Zone, and region interruptions are included in these rules.

Evaluate

The AWS Resilience Hub‘s evaluation examines an application’s constituent parts to identify any potential resilience flaws using best practices from the AWS Well-Architected Framework. These may be brought on by incorrect configurations, unfinished infrastructure setup, or circumstances requiring more configuration enhancements.

Suggest

It offers practical suggestions for enhancing resilience. Additionally, the resilience evaluation produces code snippets that assist you in creating Standard Operating Procedures (SOPs), or recovery procedures, as AWS Systems Manager documents for your applications. To assist the operator in promptly recognizing any modifications to the application’s resilience posture after deployment, AWS Resilience Hub creates a list of suggested Amazon CloudWatch monitors and alerts.

Validate

Before putting your application into production, you may utilize AWS Resilience Hub to test and confirm that it can fulfil its resilience targets after updating the application and SOPs to include the resilience assessment’s suggestions. AWS Fault Injection Simulator (FIS), a chaotic engineering service, is linked with AWS Resilience Hub to offer fault-injection simulations of actual failures to confirm that the application recovers within the specified resilience targets. Network issues or an excessive number of open connections to a database are examples of this.

For continuous resilience validation, you may incorporate AWS Resilience Hub‘s resilience testing and assessment into your CI/CD workflows using its APIs. It is possible to make sure that modifications to the application’s underlying infrastructure do not jeopardies resilience by incorporating resilience validation into CI/CD pipelines.

Benefits

Reduce outages

To minimize downtime, continuously verify and monitor application resiliency.

Evaluate resilience targets

Assess resilience goals, such as the Recovery Time and Recovery Point objectives.

Proactive issue management

Find and fix problems before they affect production.

Optimize continuity

Reduce recovery costs and maximize business continuity.

Use cases

Uncover potential weaknesses

Makes use of fault-injection simulations of actual failures to verify the efficacy of alarms and recovery standard operating procedures (SOP).

Protect mission-critical applications

Helps you develop recovery protocols and offers practical suggestions to increase resilience.

Help meet contractual and regulatory requirements

Helps satisfy legal and regulatory standards by maintaining an audit record of occurrences during both scheduled and unforeseen outages.

Pricing details

  • Fee for the first three evaluated applications for a period of six months Free.
  • Monthly fee for each evaluated application (beyond the free period or more than 3) $15 for each application.

Pricing examples

Your monthly cost would be determined as follows if you had described five applications in AWS Resilience Hub (beyond the free time) and four of them had previously been evaluated for resilience:

Four times $15 for each application is $60, which is the total amount of applications described and evaluated.
