I was asking a CIO colleague of mine what to do about spare parts for legacy systems:

“Easy you have none. We have no spare parts for any servers that are out of warranty/support – they are decommissioned with the servers”

But what about supporting the hardware, keeping everything running? I ask

“Simple, I have no spare parts, in the event of a legacy system failing, you have two choices either a virtual pre-provisioned server or a physical one which we also have started pre-provisioning. I am not wasting my budget, my time and effort fixing a server that has no economic value, and which will be replaced in a few months as part of our virtualization project.”

In the event of a failure, do you not therefore run at operational risk? I ask

“If you think about it in some respects no. Business sponsors are made aware that their system is out of support, and that we have no spare parts (new or recycled), therefore in the event of failure we would provide them with a replacement virtual machine or if that did not suit a physical one. There is no risk so to speak, everyone understands the message and the financial savings implications, I can spend £100,000 a year supporting legacy systems, or I can invest that time, that finance on moving our infrastructure ahead – those that feel they operate in a situation of heightened risk can prioritize or request they be targeted for a replacement server.

By offering to provide recycled hardware for spare parts places me in the situation where I am liable when we do not have spare parts.”
