Three dimensions of Virtualisation

Another piece of, what I hope is wisdom, coming from my last three months of customer conversations is that virtualisation has three dimensions.

We use virtualisation to make large systems small. I call this “Atomisation”. We can also use virtualisation technologies to make many components seem as one, this is of critical use for horizontally scalable services, and I call this “Aggregation”. The third dimension is “Longevity”. Maybe I should play around with “Age” as a word, so each dimension has a mnemonic starting with “A”, but by using a Type II hypervisor, one can protect old software against platform innovation and continue to run it until its business case changes or expires.

How new is Cloud Computing?

I have spoken to several of Sun's customers over the last 3 months about Cloud Computing and have often used the following quote.

“When we build a distributed computing platform and run one application on it, we call this HPC, when we build a distributed computing platfrom and run many copies of one application on it, we call this Web 2.0, and when we build a distributed computing platform and run many applications on it, we call it Cloud Computing.”

Who said it? Me!

Its not quite true, but the difference between the platforms is not necessarily as great as some might like to make it seem. Web 2.0 platforms are rarely as economic as running many copies of one application but its a pretty small portfolio often supporting only one end-user application. I accept that elasticity and metering are important, unsolved, or not well solved problems in the cloud world but I think the quote is worth publishing here and repeating and offers insights into planning an evolving the next generation of IT platforms.
