Test EC2 reliability with Gremlin. Run CPU, Memory, Disk, and Shutdown experiments plus built-in reliability tests to validate autoscaling and failover.
Amazon EC2 runs a significant portion of workloads on AWS, which means EC2 failures rarely stay contained to EC2. A single lost instance can cascade into slow response times, failed transactions, and lost revenue long before your monitoring tools show anything unusual.
Track down those failures and prevent them from causing outages with the Gremlin Reliability Platform. Install the Gremlin Agent on your instances, then use Chaos Engineering experiments and standardized Reliability Test Suites to prove your services survive the failures AWS will eventually hand you. With Gremlin, you can:
- Prove your services survive instance loss. AWS retires hosts, degrades hardware, and reclaims Spot capacity on its own schedule. Shutdown experiments let you take an instance offline on your terms and confirm that traffic reroutes, replacements launch, and your customers never notice.
- Validate the Multi-AZ architecture you're paying for. Redundancy on an architecture diagram is not the same as redundancy under load. Blackhole experiments isolate an availability zone so you can watch the remaining zones absorb the traffic, turning an assumption into evidence you can show your leadership team.
- Find resource limits before your customers do. CPU, memory, and disk experiments apply pressure to an instance while you watch how your service responds. You learn where autoscaling triggers, where health checks fire, and where your thresholds were set years ago and never revisited.
CPU scalability - Linux
Test that your Linux-hosted service scales as expected when CPU capacity is limited. Gremlin consumes CPU in three stages—50%, 75%, and 90%—to validate scaling thresholds.
CPU scalability - Containers
Test that your service scales as expected when CPU capacity is limited. Gremlin will consume CPU in 3 stages: 50%, 75%, and 90%.
Region Evacuation - Linux
Test your Linux-hosted service's availability when an entire cloud region becomes unavailable. Verify that traffic automatically fails over to backup regions without impacting the user experience.
Zone redundancy - Linux
Test your Linux-hosted service's availability when a randomly selected availability zone becomes unreachable. Verify that traffic fails over to secondary zones.
* Gremlin is designed to work on any cloud platform that provides Linux or Windows hosts. We haven't individually tested every service we cover, and not all are officially supported. Check our compatibility documentation for tested operating systems and known caveats, or get in touch if you don't see yours.
