So you are a loyal VMware customer. You have licenses for vSphere 4 and you are about 40% virtualized. Based upon the revised vRAM entitlements in the revised vSphere 5 licensing, you think you are going to be OK as you progress through the more demanding business critical purchased and custom developed applications that lie in front of you. Continue reading vSphere 5 Licensing – The Role of Cross Platform Management Tools and the Hotlink SuperVISOR
There is a great deal of marketing hype about which hypervisor is better but I have spent some thinking about this and really have to wonder if the hypervisor is what we should really be focusing or concentrating upon. A lot of third party vendors are starting to port their products to be able to work with both hypervisors. To see a list of some of these products check out the post Growth of Citrix and Hyper-V EcoSystems. What about the management server itself? Isn’t this really the center of the virtual universe? When third party application vendors design their applications to work with VMware or Microsoft hypervisors they have been writing plug-ins for their product to work inside the management server systems and/or its client.
I am not going to get into the discussion of which platform is better. This argument and debate has been going on for quite awhile and the fact of the matter is no one platform will be the best at everything. This is why most large scale datacenters will have a mixture of Windows, Linux and possibly a mainframe or two. I believe the same thing will happen with the virtual infrastructure in that there will be no “one size fits all.” There are enough marketing comparisons posted everywhere on the internet that I find myself looking at another more interesting fact that currently no virtual management product out there will control and manage all the different types of hypervisors. So far what I had found is that SCVMM is able to control both Microsoft Virtual Systems as well as the VMware Infrastructure/vSphere and VirtManager is able to manage KVM and Xen.

In many ways, the IT world has gone certification happy. Nearly every job requirement lists certifications as well as length of service, however, in the realm of cloud computing and virtualization what do these certifications mean? Are they even valuable? Is there a general enough certification that covers all the hypervisors, is there a third party certification available?
These questions are important to answer before deciding on which certifications to undertake as well as which to request when putting out the job request. Further there are several styles of certifications, these being:
- Those that can be studied to achieve
- Those which require hands on experience to achieve Continue reading What User Virtualization Certifications are Necessary?
I was in this industry when the IBM PC was launched in the early 1980’s. As soon as the first model was replaced with one that had a 5 MB (imagine that) hard disk, and the first personal productivity applications came out (WordPerfect, VisiCalc, and Harvard Graphics) the IBM PC morphed from a toy to a serious tool that users and businesses could use to enhance their productivity through computing without having to plead for resources and support from what was then a mainframe and mini-computer dominated data center.
