I gave at talk at the Gartner Infrastructure, Operations & Data Centre Summit on data centre consolidation yesterday. My slot was only thirty minutes so I decided to focus on aligning virtualisation technologies to consolidation goals.
With the proliferation of products in this space, it has become increasingly important that IT architects understand both the technical and business merits of the technologies. While many of the products produce a similar high level results (usually more applications on a particular piece of hardware), how they achieve this may greatly impact the overall success of a consolidation project. For example, if you have outsourced your infrastructure and are paying on a per operating system instance basis, then applying hypervisor-based products that virtualise hardware will not help you achieve your goals (and might actually increase your costs due to a control instance). Likewise, virtualising at the operating system may unnecessarily limit your flexibility when you only need to raise system utilisation.
It was too bad that I only had thirty minutes as I have a lot of material on the topic. I really wanted to describe a decision tree for the process -- and some of the consequences -- but I barely got through what I had on the slides as it was. All together, I probably have almost enough for the virtualisation chapter of my book revision. When I get it into beta form, I'll post it here.
