Thanks, Irving. That’s extremely helpful.

Hi Gabriel,

In my Chef server load-testing experiments I settled on an optimum size of c3.xlarge for the frontends and c3.2xlarge for the backends.  It's important not to skimp on backend storage - I used EBS-Optimized instances and SSD-backed EBS volumes. 

At 2500 nodes you could probably start with smaller instances, but it's highly dependent on your converge interval/splay and also the amount of work each run puts on the depsolver and search endpoint.

Ohai!

I'd like to hear people's experiences with the Enterprise Chef AWS HA implementation. In particular, I'd like to know how folks are sizing the instances, and how many nodes they're handling. I'm looking to support around 2500 nodes for the get go, but will need to support up to ~10,000. 

Thanks in advance!
