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.
