Summary
Redis cache can improve the performance and scalability of systems that rely heavily on databases. Performance is improved by temporarily copying frequently accessed data to fast storage located close to the application. With Redis cache, this fast storage is located in-memory with Redis cache instead of being loaded from disk by a database.
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.
