Within the EdWeb infrastructure, the varnish and memcache servers have already reached their operating system (CentOS 6)  end of life. The move of varnish to CentOS 7 is believed relatively straightforward and will be picked up in support. However, the upgrade of the memcache servers requires code changes and needs to be delivered as a project given the system's history of sensitivity to losing individual cache components. This project will oversee the necessary infrastructure upgrades to the affected servers.
