Wichert Akkerman Plone Deployment Practices The Plone.Org Setup

2,837

Published on

The plone.org and plone.net websites are the first confrontation with Plone for most users. It is important that they perform well and are stable. With almost 4 million page views per day and thousands of LDAP users plone.org and plone.net are examples of a complex deployment setup requiring LDAP, caching and load balancing - all on a single machine. I will describe how the Plone websites are build and how those practices can be applied to other sites, making it possible to scale upwards to bigger sites or make smaller sites more efficient.
