How we spent Friday night coming back online before Instagram and others

I use a similar process to this in my infrastructure - I use Puppet to configure instances, then a Fabric command to create new AMIs based on these Puppet configurations.

This gives the best of both worlds - version controlled configuration files, and an automated process for making new AMIs. Instances also boot quickly, as nearly all of the configuration is baked-in to the image.

Using EC2 tags gives you even more room for automation here.

Can you elaborate on how you use EC2 tags? The only thin we use them for is to mark a new instance as bootstrapped once puppet finishes.

It also sounds like you could pretty easily make your AMI creation step a job in your CI software.
