In today’s always-on, cloud-native world, building resilient applications is not just an option — it’s a necessity. Traditional testing methods focus on verifying functionality under normal conditions, but they often fail to assess how an application behaves under stress, failure, or unexpected conditions. This gap is where Chaos Engineering comes into play, helping organizations proactively test and strengthen their systems by intentionally injecting failures and observing how they respond.

Enter AWS Fault Injection Simulator (FIS), a powerful tool designed to bring chaos engineering to your AWS infrastructure. AWS FIS allows you to simulate real-world failure scenarios in a controlled environment, helping you identify weaknesses and improve your system’s resilience before they manifest in production.

In this comprehensive guide, we’ll explore how to use AWS FIS to build and test resilient cloud applications. We’ll cover everything from setting up FIS…
