KVM? Us? Amazon erases new hypervisor from AWS EC2 FAQ

Amazon Web Services has quietly edited its FAQ in which it revealed it has created a new KVM-based hypervisor and will use it instead of Xen for future instances.

Is it the right time to virtualize?

Picture the scene. You’ve run your legacy infrastructure into the ground. You bought it six or seven years ago with a view to depreciating the hardware over four years, or perhaps even three, so it’s done its time and then some. Now it’s starting to get flakier than you can live with, and as your channel partner’s spares supply …

vSphere scales up, if you're willing to ditch a switch or server

If higher data rates and larger numbers of broadband devices are an mobile network …

Amazon adds Hyper-V file support to its storage gateway

Amazon Web Services dominates the public cloud, but its hybrid cloud story is currently weak. Microsoft, by contrast, is gaining strength in the cloud by the day and its Azure Stack looks like re-defining hybrid cloud by making the on-premises portion indistinguishable from Azure. Azure Stack's preview releases suggest that …
