Azure Managed Redis

Why the other options are wrong
- A. A Redis instance that you run on your own VM
- Your own VM means more to run.
- B. Azure Cache for Redis, on a tier that is being retired
- Do not start on a service being retired.
- C. A single virtual machine with Redis installed by hand
- A single VM is a single point of failure.
