I also assumed that it's just a webshell to connect to your existing instances.

Only now I realized that it's a 1-click launch of O&M instance with persistent home directory (and in the future maybe persistent image as well).

I hope they will give the ability to switch instance type.

It's a good pattern to have an O&M node, where people are allowed to ssh, which will have all the devops scripts.

You can do this with AWS' t2.micro instance and launch hyperlink and some custom webshell, but it will not be that integrated as Google Cloud Shell.
