About Compatibility Matrix VMs (Beta)
This topic describes Compatibility Matrix VMs and their capabilities for testing your applications.
About Compatibility Matrix VMs
Compatibility Matrix VMs provide isolated Linux environments for testing your applications. Unlike clusters, VMs give you full control over the operating system (OS) and allow you to test installation methods that require direct OS access.
You can use Compatibility Matrix VMs for testing and troubleshooting VM-based installations for your application with Replicated Embedded Cluster.
For information about creating clusters with Compatibility Matrix to test Kubernetes-based deployments and Helm installations, see Create and Manage Clusters.
