Building Resilient Serverless Systems
Design highly available and fault-tolerant serverless architectures by incorporating patterns like circuit breakers, retries, and idempotency across your functions.
Building Robust Serverless Systems
Welcome! In this lesson, we'll dive into designing highly resilient and fault-tolerant serverless applications. Even though AWS manages much of the infrastructure, your functions still need to handle failures gracefully.
We'll explore key architectural patterns to ensure your applications remain stable and performant, even when things go wrong.
The Reality of Distributed Systems
In a serverless world, your functions often interact with many other services: databases, APIs, message queues. These interactions happen over a network, and networks can be unreliable.
- Transient Failures: Brief network glitches or service slowdowns.
- Downstream Service Issues: A service your Lambda calls might be temporarily unavailable.
- Unexpected Data: Malformed input can cause your function to crash.
Designing for these "failures" is crucial for a stable system.
