More on Cloud Server Performance – Updated!

Following on from my previous post, I thought I would do a little more work on cloud server performance.  First, it’s worth looking at the underlying hardware serving virtual servers in the cloud.  As I’ve been using CentOS as the base O/S for my testing, it’s pretty simple to get a summary of the CPU stats from each virtual machine.  ...

Is The Performance Of All Cloud Servers The Same?

One of the benefits of delivering Infrastructure as a Service (IaaS) through the cloud is an abstraction from the underlying hardware delivering the service.  There’s no requirement to understand what technology is being used to deliver, for example, cloud servers.  The specification of a cloud-based server is based on a few simple metrics, CPU, memory and disk space.

VMware Release Zimbra as an Appliance

At the beginning of this year, VMware announced they were to acquire Zimbra, a provider of email and collaboration software, from Yahoo.  Although the move was widely reported, it wasn’t on the face of it the most strategic of VMware’s moves.  The acquisition does provide VMware with more access into the business of delivering applications as well as infrastructure to ...
