Following on from my previous entry and these two items:-
- Q&A: VMware co-founder Mendel Rosenblum
- Operating Systems never did exist, and the ones we have are doomed…
This has really made me think as to where virtualization will lead us. It either has to become the OS, and VMware already state that ESX server has millions of lines of code (not dissimilar to many OSes) so at some point the virtualization product becomes the OS and the OS becomes a function library. Or maybe not!
Intel, AMD and other hardware vendors are adding virtualization support like crazy to their hardware so maybe the next step is the virtualization layer to really move into the hardware and BIOS. With multi-core processors coming thick and fast (Intel forsee 80 cores in a few years) the ability to carve up your box into multiple virtual boxes becomes much more relevant. And with all the virtualization handled in the hardware we will have much less overhead on the next layer from virtualization. Really this is just the next step on from the blade arhitecture we have now, instead of slots in a rack we could end up with scokets on a motherboard. Add a few more cores and viola you have added a huge amount of capacity to the system. As with everything at some point the hardware moves down to the chip level, AMD will start the ball rolling as they add GPUs into their chips following their ATI purchase.
This is why VMware needs to move into the system management space as that is where the real value is, operating systems are becoming commodity items, virtualization will just be another trick for the hardware vendors, so the real value is in managing this whole infrastructure and making sure that the workloads that needs the resource and QoS get it.
