Windows DNS redundancy

Test your Windows-hosted service's availability when its primary DNS server is unreachable. Verify that DNS failover routes traffic correctly through secondary providers.

Linux host failure

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.

Shutdown

Linux

Container redundancy

Test resilience to container failures by shutting down a randomly selected container. Verify that your container runtime automatically restarts or replaces it.

Kafka broker load on container processing latency

Test the impact of I/O usage on pipeline throughput and partition synchronicity. As I/O usage increases, pipeline performance will decrease, but should stay within expected bounds. Be sure to select your Kafka nodes.

Kafka broker load on Linux processing latency

Test the impact of I/O pressure on Kafka broker throughput and partition synchronization on Linux hosts. As disk I/O usage increases on the broker's host, pipeline performance will decrease, but should stay within expected bounds.

Kubernetes node redundancy

Test your Kubernetes cluster's node redundancy by dropping all network traffic to a node.

Container region evacuation

Test your containerized service's availability when an entire cloud region becomes unavailable. Verify that traffic automatically fails over to containers in backup regions without impacting the user experience.

Disk I/O scalability

Test that your service scales as expected when Disk I/O is limited. Gremlin will carry out many read and write operations in the target's /var/tmp directory. Estimated test length: 20 minutes.

Linux memory scalability

Verify that your Linux-hosted service scales as expected when memory is limited. Gremlin increases memory utilization in three stages—50%, 75%, and 90%—to validate memory management.

Avoid downtime. Use Gremlin to turn failure into resilience.

Gremlin empowers you to proactively root out failure before it causes downtime. See how you can harness chaos to build resilient systems by requesting a demo of Gremlin.
