Mozilla's recent CI improvements saves roughly 60-70% on our AWS bill

bhearsum, catlee, glandium, taras and rail have been working hard for the last few months at cutting our AWS bills by improving Mozilla RelEng's CI.

From looking at it, I can say that with the changes they have made we're roughly saving the 60-70% on our AWS bill.

If you see them, give them a big pat on the back, this is huge for Mozilla.

Here’s some of the projects that helped with this:

• Jacuzzis
• Experiments with smaller pools of build
• Firefox builds are way cheaper now!
• EC2 spot instances experiments
• AWS, networks and burning trees
• More and faster CI for less on AWS
• Analyzed shared cache on try
• Cost-efficient continuous integration
• Linux and Android try builds, now up to twice as fast
