Linux host failure
Description
Prepare for Linux host failures by shutting down a percentage of your hosts and observing the results. Validate that your infrastructure handles host loss without impacting service availability.
What this Scenario does
This Scenario shuts down a percentage of your Linux hosts, simulating real-world hardware failures, power outages, or cloud instance terminations. It lets you observe whether your infrastructure can handle the loss of multiple hosts simultaneously.
Why run this Scenario?
- Validate that your load balancers detect failed Linux hosts and redistribute traffic to healthy ones.
- Test your infrastructure's capacity to absorb workload when hosts are lost.
- Verify that auto-recovery mechanisms (such as cloud auto-scaling groups) replace failed Linux instances.
- Build confidence in your migration to cloud-based infrastructure by understanding host failure behavior.
Expected outcome
When a percentage of Linux hosts are shut down, remaining hosts absorb the workload and services continue running without interruption.
