Tired of wrestling with server provisioning? Sumo!
Want to fire up a one-off EC2 instance, pronto? ec2-run-instances got you down? Try Sumo.
$ sumo launch
---> Launching instance... i-4f809c26 (1.5s)
---> Acquiring hostname... ec2-67-202-17-178.compute-1.amazonaws.com (26.7s)
Logging you in via ssh. Type 'exit' or Ctrl-D to return to your local system.

Linux domU-12-31-39-04-31-37 2.6.21.7-2.fc8xen #1 SMP Fri Feb 15 12:39:36 EST 2008 i686
...
root@domU-12-31-39-04-31-37:~#
Later…
$ sumo terminate
ec2-67-202-17-178.compute-1.amazonaws.com scheduled for termination
You can also manage multiple instances via “sumo list” and specifying hostname or instance id as arguments to the launch, ssh, and terminate commands.
Setup
Dependencies:
$ sudo gem install amazon-ec2 thor
Then create ~/.sumo/config.yml containing:
---
access_id: <your amazon access key id>
access_secret: <your amazon secret access key>
ami: ami-ed46a784
If you run any production machines from your EC2 account, I recommend setting up a separate account for use with Sumo. It does not prompt for confirmation when terminating an instance or differentiate between instances started by it vs. instances started by other tools.
Features
Launch, ssh to, and terminate instances.
Sumo creates its own keypair named sumo, which is stored in ~/.ssh/keypair.pem. Amazon doesn’t let you upload your own ssh public key, which is lame, so this is the best option for making the launch-and-connect process a single step.
Anti-features
Sumo is not a cloud management tool, a monitor tool, or anything more than a way to get an instance up right quick. If you’re looking for a way to manage a cluster of production instances, try one of these fine tools.
