Xen is an example, but, more generally, virtualization has been the big story in systems software for the period mentioned in this article (post-2000). VMware came out of systems research at Stanford and Xen out of Cambridge. The cloud world of AWS/Azure/GCE with tens of millions of VMs running for pennies per hour is a radical shift in how we think about systems. The new wave of Docker/containers promises to extend this idea even further up the stack. How can we call that "stagnation in software" since 2000?
- wrs 12y agoVirtualization as an operating system design feature predates that entire chart. A lot of the hard problems in the Xen/VMWare research related to implementing virtualization on a processor architecture (x86) that was extremely popular, but didn't actually support virtualization. Which is just the kind of stagnation he's talking about, I think.
