It's doesn't have a UI, but I wrote a command line tool called Overcast that lets you create/manage/destroy/reboot DigitalOcean and Linode VMs. Support for AWS is on the roadmap. http://andrewchilds.github.io/overcast
# Create a new Ubuntu 14.04 instance on DigitalOcean
$ overcast digitalocean create db_01 --cluster db
# Create a new Ubuntu 14.04 instance on Linode
$ overcast linode create db_02 --cluster db
# Configure both instances in parallel
$ overcast run db install/core install/redis --parallel
$ overcast expose db 22 6379 --parallel
# Interact with both instances at once over SSH
$ overcast ssh db
# Reboot, snapshot, destroy, etc
$ overcast digitalocean snapshot db_01 db_01_snapshot
$ overcast digitalocean reboot db_01
$ overcast linode destroy db_02
Its less "often" and more "convenient". If you need to make a chance, reboot, shutdown, etc, is it easier to open your browser, login to DO, find the droplet, etc? Or two clicks in the menubar?
This is very cool. I made the Rackspace and Slicehost apps back in the day and I always wanted to make a tool like this to manage Rackspace servers. Unfortunately I never got around to it.
