Introduction
This page will describe the UMO infrastructure supporting the UMO service.
Caching
We are currently using Squid for caching of images and content. This has been quite scalable but we need to start considering using Apache2 + mod_cache/mod_proxy to be able to handle more types of HTTP 1.1 requests.
Database
We are using MySQL 4.0.22 for the database. Moving forward, we will be looking at using MySQL 4.1.x in order to take advantage of subselects. We currently have this all on one database server but moving forward we need to consider a master/slave arrangement for redundancy sake.
