Rethinking Your Already Virtualized Low Hanging Fruit

The drive to virtualize business critical workloads is going to require more vSphere licenses. Shifting low hanging fruit workloads to Hyper-V may free up licenses. But it creates a cross-hypervisor management problem that could erode all of the savings from Hyper-V licensing. This puts a premium on cross-hypervisor management solutions.

Defense in Depth: Encryption within the Virtual Environment

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.

Will access to VMware’s source code change the hypervisor threat landscape?

Many of the virtualization security people I have talked to are waiting patiently for the next drop of leaked VMware hypervisor code. But the real question in many a mind is whether or not this changes the the threat landscape and raises the risk unacceptably. So let’s look at the current hypervisor threat landscape within the virtual environment to determine if this is the case, and where such source code will impact. Are there any steps one can take now before the code drop is complete to better secure your environment?

Ecosystems for Both VMware and Microsoft Hypervisors

Since the start of the Windows 8 Public Beta, there has been a great deal of discussions and comparisons galore. There have been points made that Microsoft Hyper-V will be good enough to draw good consideration in companies looking to the future. For me personally, feature comparison was not my first consideration. One measurement that I consider is the eco-structure of the technology or in other words, how large is the 3rd party partners and products supporting both the technologies?

VMware Licensing Past and Present Compared to Hyper-V

When we look for patterns from the past, sometimes we can really get a good idea of what the future might entail.

If you take a look at the way VMware has rolled out licensing changes during each of the major releases you can see a pattern and get an idea of what the future may bestow on us. When Virtual Center was first released, vMotion and vSMP were licensed separately from Virtual Center as an add-on for Virtual Center.

Once VMware ESX3 was released, vMotion and vSMP pretty much became a standard feature included in ESX3. Virtual Center was still sold separately and then VMware presented three licensing models for VMware ESX3.
