AWS Fault Injection Service
AWS Fault Injection Service helps teams improve resiliency and performance through controlled experiments. It allows you to simulate failures and disruptions within your infrastructure to identify weaknesses before they impact production systems.
This service fits organizations ready to proactively test their systems' stability under stress. Since there is no free tier and it operates on a pay-as-you-go model, you will incur costs for every experiment, making it a budget consideration for smaller teams or sporadic testing needs.
