As it currently stands, it is as difficult to get data onto Azure - you're supposed to manually deploy a container yourself to whichever cloud provider you are using, there is no "Managed Garnet" solution yet (but given hype it will probably arrive at some point).

Either way you can see contributions to add more commands here: https://github.com/microsoft/garnet/pulls?q=is%3Apr+add+comm...

With that said, I'm slightly skeptical of/worried about Garnet but the reason is different - it received a bit too much hype soon after going public and I'm concerned it will be subject to corporate politics that often plague projects like that.
