Summary

Completed

In this module, you learned about Azure disk caching and how it potentially improves performance. You used the Azure portal and Azure PowerShell to manage disk caching for your VM.

Once you have an Azure VM disk caching strategy in place, you can then quickly and easily deploy new VMs and disks with the optimum disk cache settings by using scripts and templates.

Clean up

The sandbox automatically cleans up your resources when you're finished with this module.

When you're working in your own subscription, it's a good idea at the end of a project to identify whether you still need the resources you created. Resources that you leave running can cost you money. You can delete resources individually or delete the resource group to delete the entire set of resources.
