Previously: Tomcat Clustering, Varnish and Blue/Green deployment - part 1

In part 1, we set up a Tomcat cluster with parallel deployement and cluster-wide deployment. Go back to the first part if you have not read it, this article assumes that you have read it.

At Claranet, we aim to provide the best possible uptime to our customers while encouraging them to adopt an agile workflow where they push new versions of their apps often and seemlessly.

Because most of our clients are using PHP (or Ruby), we usually help them to setup Capistrano: it’s efficient and there are a lot of plugins for different frameworks (capifony for instance). Varnish is also quite often in our list of requirements, because of its sheer capacity to absorb trafic and deliver content.
