Web Server Cloud

Description

The HKU Web Server Cloud is set up in June 2009 to support departmental web sites. The Cloud is a system running Virtual Machines (VMs). Each VM can run a virtual web server, e.g. it looks like the whole server is provided as a departmental server. When one virtual web server fails, the VM will be restarted on another physical server automatically.

A virtual web server will be provided to host the web site of an interested department. Each virtual web server consists of 1 virtual processor, 2GB virtual memory and 50GB virtual disk space (including the operating system and system software). The department would have to co-ordinate the resources amongst all web services in the same department including approval of additional account application on the virtual server.
