Elevator Pitch
In today’s cloud‑driven world, organizations rely on AWS to power their most critical application, but reliability and resiliency challenges continue to surface as architectures grow more distributed, dynamic, and complex. That’s why we built RaaS, an intelligent Resiliency & Reliability Platform.
Description
RaaS is built on top of AWS Resilience Hub and AWS Fault Injection Simulator, enabling continuous evaluation of an application’s resilience posture and scoring it against defined RTO/RPO objectives. The service analyzes infrastructure across multiple layers Application, Cloud Services, Availability Zones, and Regions and provides targeted recommendations to strengthen resiliency at each layer.
When integrated into the CI/CD pipeline, RaaS empowers developers to deploy with full confidence, knowing that every release is automatically validated against resiliency best practices and recovery objectives. This removes the operational burden of manually verifying RTO/RPO compliance and ensures that resiliency becomes a seamless part of the delivery workflow.
A major advantage of RaaS is its ability to run automated fault‑injection tests—such as network disruptions, Availability Zone outages, and regional failures—to validate how the system behaves under real‑world failure scenarios. These experiments expose weaknesses early and help teams proactively harden their architecture. RaaS also uncovers critical blind spots that are often overlooked during infrastructure design, such as: When should cross‑zone load balancing be enabled? Why are health checks essential for failover? How does DNS TTL impact RTO during failover events? Which DNS routing policy is appropriate for the application’s recovery strategy?
By answering these questions, RaaS ensures that resiliency is engineered intentionally rather than assumed.
Notes
I, Rajasekar Munuswamy have close 20 years of experience in Information Technology. I have worked across multiple technologies, and I have been more involved in Cloud Infrastructure Reliability and Resiliency. I have a successful track record of evaluating cloud infrastructure architecture across complex stack and performed various chaos experiments successfully. In my current organization, I have been leading the AWS Reliability and Resiliency tower to ensure and continuously improve the resilience posture of the AWS Infrastructure.
