-Microsoft and its OEM, OS, and Kubernetes partners have a validation program for Azure Arc data services. This program provides comparable test results from a certification testing toolkit. The tests evaluate feature compatibility, stress testing results, and performance and scalability. Each of these test results indicate the OS used, Kubernetes distribution used, HW used, the CSI add-on used, and the storage classes used. This helps customers choose the best storage class, OS, Kubernetes distribution, and hardware for their requirements. More information on this program and test results can be found [here](validation-program.md).
