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.
