 # Create a chaos experiment that uses an agent-based fault with the Azure portal
 
-You can use a chaos experiment to verify that your application is resilient to failures by causing those failures in a controlled environment. In this article, you cause a high CPU event on a Linux virtual machine (VM) by using a chaos experiment and Azure Chaos Studio. Running this experiment can help you defend against an application from becoming resource starved.

In this article, you cause a high % of CPU utilization event on a Linux virtual machine (VM) by using a chaos experiment and Azure Chaos Studio.

 You can use these same steps to set up and run an experiment for any agent-based fault. An *agent-based* fault requires setup and installation of the chaos agent. A service-direct fault runs directly against an Azure resource without any need for instrumentation.
