The side benefits of virtualisation

I posted an update recently on our ongoing virtualisation project Virtualising takes time but it is worth it which is moving along quite nicely now - albeit with a few hiccups along the way (and one or two long delays). One of the useful side effects of this project has been forcing us to review, rethink and address services that we were running. The old adage says “if it an’t broke don’t fix it” but setting time aside to look at what you are doing and more importantly why is proving quite refreshing - it’s almost like having a technological spring clean! Over time, programs, that are useful at the time, tend to get installed and used for a while then a new server gets put in and some of these older programs end up taking up valuable space and become their own problem areas. Time is not always available for looking at these small issues so they tend to get left so it handy to finally get to revisit them.

As an example, we used to host our own website and our own FTP server. Migrating the web site to a hosted service and using file transfer services such as sendspace instead of FTP have moved a lot of traffic (especially unwanted hack attempt traffic on the FTP connection!) away from our network. The side benefits of a less stressed firewall and a freeing up of bandwidth have been welcomed and with a number of other servers left to analyse it will be interesting to see what else turns up.
