By isolating a server's unique +properties into a set of patches to +initialization scripts and other selected +files, deployment of a new server can occur in +a few seconds. To capture changes to a +server's configuration that occur while it is +running, we discuss using an LVM snapshot to +hold changes to selected files. By separating +the initialization and file data that make a +linux server instance unique, that data can be +stored and retrieved in a number of ways. We +discuss storing and retrieving different +initialization patches over the network and +integration of these capabilities into the Xen +tools. Potential uses for the techniques +demonstrated in the paper include capacity on +demand, and new methods of provisioning +servers and workstations. |
