vCloud, OpenStack, Pets and Cattle

I keep bumping into discussions where people try to compare vCloud (Director) and OpenStack. The last one that caught my attention was an email from a colleague that went like:

Cloud and the Three IT Geographies (Silicon Valley, US and Rest of the World)

In the last 3 years I spent most of my time advocating that the cloud world is marching at a (very) different pace based on where you are and who you are.

VMware Distributed Storage – This is Where the (Cloud) World Collapses

At VMworld 2012 VMware showed something dubbed Distributed Storage. If you were in SF and you missed it, I strongly suggest you watch the recording of session INF-STO2192. The demo in particular is very cool.

The Evolution of x86 Server Architectures

Azure Virtual Machines: what sort of cloud beast is it? (UPDATED)

A few weeks ago, at TechEd, Microsoft announced Azure Virtual Machines. In other words their response to a growing sentiment that PaaS is too early for many and IaaS is the natural first step into the cloud (let’s put SaaS aside for a second).

Typical VXLAN Use Case

One of the problems VXLAN is supposed to solve is the possibility to decouple (and abstract) the compute capacity from the underling network configuration. A lot of people whose background is solely in the compute space now know that there is a solution but don’t really get why there is a problem in the . . . → Read More: Typical VXLAN Use Case

VMware wants to be the VMware of Networking

There have been a lot of discussions lately about SDN (Software Defined Networking).

Arguably SDN may mean a lot of different things to a lot of different people. If you ask the like of Facebook, Google and academic researchers they will probably tell you that SDN is all about gaining full visibility (and . . . → Read More: VMware wants to be the VMware of Networking
