help AWS Fault Injection Simulator FAQ
What is the primary purpose of AWS Fault Injection Simulator?
AWS Fault Injection Simulator (FIS) is a fully managed chaos engineering service used to test how your applications respond to unexpected failures. By injecting controlled faults, it helps you identify hidden weaknesses in your AWS architecture before they cause real outages.
What types of failures can AWS FIS simulate?
The service can simulate a wide variety of disruptions, such as terminating EC2 instances, adding network latency, or exhausting CPU resources on your containers. You can use pre-built templates to easily disrupt specific AWS services like ECS, EKS, or RDS databases.
Does AWS Fault Injection Simulator require me to write custom scripts?
No, FIS eliminates the need for custom chaos engineering scripts by providing an intuitive console and API for running experiments. You simply define an experiment template, select your target AWS resources, and let the managed service handle the injection.
How is AWS FIS billed when running chaos experiments?
AWS charges for FIS based on the number of actions performed and the total duration of your experiment runs. You pay exactly for the chaos engineering execution time you use without any upfront costs or long-term service commitments.
