What's next for Virtualisation?

In discussing virtualisation, a speaker this morning suggested that the two biggest inhibitors to using virtualisation technology are security and scalability. Both of these are opportunities for Solaris. A number of security conscious customers use Solaris 10 with trusted extensions, to run a container, with a virtual box instance, hosting windows. They're delighted because it allows them to protect their network from windows vulnerabilities (It also allows them to protect their data from windows vulnerabilities; you can prohibit the container from acquiring data via any i/o device). The new scalability problem is to scale on a CPU. Sun's Niagara processors are the most threaded CPUs in common use, but Intel and AMD are also pursuing multi-threaded CPU designs. They and their customers need an operating system that scales across the new architectures. Some users/customers are now evaluating work/kwatt, and thus being busy helps you score high in these tests. Scalability = Performance, and Performance = Eco. You still draw power even when not busy.

I've been doing some research regarding the security implications of v12n, as Brian and I are booked to present on this to an organisation I have a long-standing relationship with, next week.

You might be surprised to know that some of the primary risks, particularly in an LDom world, can be mitigated by the judicious use of crypto.

If you're in GMP next Tue or Thu, let's catch up.
