Best practices for utilizing AWS Systems Manager with AWS Fault Injection Service

This article discusses best practices for utilizing AWS Systems Manager (SSM) with AWS Fault Injection Service (FIS) to improve application resilience and reliability through chaos engineering experiments.

• FIS allows performing fault injection experiments to stress test applications and uncover potential issues
• SSM Run Command enables executing scripts across different systems and platforms
• Key best practices for SSM documents include:
  • Modular document structure
  • Clear parameter definitions
  • OS detection
  • Implementing preconditions
• Code best practices involve:
  • Idempotency
  • Proper timeouts
  • Comprehensive logging
  • Thorough cleanup procedures
  • Service state restoration

The goal is to create robust chaos engineering experiments that improve application resilience by systematically testing system responses to disruptive events.
