The emphasis today around Change Management is establishing a good
workflow to speed up the request and approval process. All well and
good, but let’s fast forward and declare that part of journey over and
pretend we’re so efficient that we can submit and approve 50 change
requests a day. While we’re at it, let’s also assume you are also
proficient at detecting and resolving collisions among a batch of RFCs.
The next challenge might be how do I really increase my level of
confidence for critical and n-tier changes. Why? Because you can’t
totally rely on analysis, sometimes you have to insert and evaluate the
change in an actual environment. Obviously you can’t do this in a real
production environment but you can in a replicated virtualized
environment.
Virtualization allows you to create multiple and different types of
abstract or logical servers on real physical machines without
dedicating the machine to a particular operating system or application
function. I’d be surprised if any IT shop today hasn’t already deployed
products like VMware, Virtuozzo, Xen etc. This technology is a great
opportunity for change management (and functional testing too) since
you can build a replica of your product environment, roll in the change
and evaluate the results. These virtual machines can be destroyed if
you are simply using it as a lab or it can be migrated directly if you
have a virtualized data center. Additionally you can create and restore
snapshots for ongoing problem analysis. Ok I admit it’s a fairly
advanced topic for the process world of ITIL but if you?re organization
is already investing in VMware or similar products then take a look at
how this technology can be leveraged to further mitigate change risk.
