New! Configuration Presets – feedback appreciated

Lets say you run a large website, with tens or even hundreds of web servers.

You’ve got a configuration change to make, and it needs to be pushed on all the servers simultaneously.

If you make the changes to one server, take a snapshot of it, and replace the others with it, you’re creating a service disruption while the servers reboot; if you write a script that makes those changes, you’ll have to remember to execute that script on any new server you bring up – not to mention the delay from one more script to execute at boot-time.

In response to this, we’ve developed Configuration Presets – a simple tool to configure services such as MySQL, Apache, and Cassandra, and push changes to a set of servers. This also makes it easy to map changes in configuration to changes in performance on your load graphs :-)

Below is a preview of this functionality – please share any feedback you might have as comments!
