OK get it.

You are looking for local disk encryption.

For Azure you can find the docs here. Mind that this is in public preview so not enabled by default.

There are also other encryption options, which you can find here.

the spilled data is written to some object store on the cloud provider.

I believe all of them apply encryption by default.

Of course it is up to you (or your colleagues) to restrict access to the storage.​

Let's say we're talking about Azure. As far as I know each VM has its own disk.
