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. But you would like a hedge and a simple way to manage the second hypervisor that is a part of that hedge. Help has arrived.
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 on. A lot of third party vendors are starting to port their products to be able to work with both hypervisors but what about the management server itself? 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.
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?
Instead of shifting workloads from internal IT clouds to external clouds via “cloud-bursting”, the most likely use case for cloud computing this year will be the import of tactical workloads from external clouds to the data center. This will create the next great end-run around IT and IT management processes.
