I meant to post this for a while, but haven't had the time, because...well, it's a new job, so I've been quite swamped. I started 2 weeks ago as a system engineer at OpenX, a company based in Pasadena, whose main product is an Open Source ad server. I am part of the 'black ops' team, and my main task for now is to help with deploying and scaling the OpenX Hosted service within Amazon EC2 -- which is just one of several cloud computing providers that OpenX uses (another one is AppNexus for example).
Lots of Python involved in this, lots of automation, lots of testing, so all this makes me really happy :-)
Here is some stuff I've been working on, which I intend to post on with more details as time permits:
* command-line provisioning of EC2 instances
* automating the deployment of the OpenX application and its pre-requisites
* load balancing in EC2 using HAProxy
* monitoring with Hyperic
* working with S3-backed file systems
I'll also start working soon with slack, a system developed at Google for automatic provisioning of files via the interesting concept of 'roles'. It's in the same family as cfengine or puppet, but simpler to use and with a powerful inheritance concept applied to roles.
All in all, it's been a fun and intense 2 weeks :-)
