Both Microsoft and VMware have revamped their product suites, and therefore their licensing, once more. As always, how you buy will dictate how you license. It has taken a bit of time for all the revamped information to percolate through to each corporate site and for all the issues to be addressed. As we did before, let us look at licensing. We will look first at the old model of Hyper-V vs VMware vSphere vs Citrix Xen vs RedHat KVM. Then, in a follow-on article, we will look at the new cloud suite models.

There is an ever-increasing number of data protection providers creating replication receiver clouds as they team up with cloud service providers. This could herald the end of on-premise tape use for some enterprises, leaving tape to be used primarily by cloud providers. There are major benefits for Quantum, Zerto, Veeam, and others to form replication receiver clouds, but these clouds are not just for storage anymore. They could be purely for storage, but this is not a big win for the cloud service providers. So why would cloud service providers be interested in being a storage endpoint for data protection? Why are they concerned with backup and offering it as a service?
VMworld 2012 San Francisco is over, and I have some time to reflect on my virtualization thoughts in general before getting ready for VMworld Barcelona. One thing I noticed is recent announcements about VMware vSphere 5.1 and Microsoft Hyper-V 2012. Microsoft and VMware both released a specific new feature to each respective platform at basically the same time. Is this a sign that Microsoft is really closing the gap on VMware? I think we are getting there, but I have also made some other personal observations on how I see virtualization in the future, and I foresee a completely different method and mindset for the future between these two companies.
While looking around the web for anything new with virtualization, I kept seeing more and more posts and articles about the new type of virtual hypervisor. Type 0, now this sounds interesting and I found these definitions for each type of hypervisor.
At VMworld 2011, VMware presented a chart that showed their progress in terms of virtualizing various workloads in their own customer base. The chart (shown below) demonstrated that VMware had made some really good progress with some really hard workloads, and mostly excellent progress with easy workloads (low hanging fruit). The interesting question is what is the best way to proceed from here on out.
The 5/31 Virtualization Security Podcast we spoke to High Cloud Security about encryption as a defense in depth, and where to place encryption within the virtual environment. This lead to an intriguing discussion about what is actually missing from current virtual environments when it comes to encryption. We can encrypt within each VM and we can encrypt within the networking fabric, as well as within the drives themselves, but currently that leaves several vulnerabilities and unencrypted locations that can be used as attack points. While we concentrated on vSphere, what we are discussing applies equally to all hypervisors.
