While VMware is still the undisputed leader in enterprise data center virtualization, it is also very obvious that Microsoft has made (and continues to make) significant inroads into both the broader data center virtualization market and into VMware’s own enterprise customer base. The general perception is that Microsoft Hyper-V is now “good enough” to run most production workloads, that it is close enough (or at parity) in functionality and performance to vSphere for customers to be able to move workloads from vSphere to Hyper-V, and that vSphere is “expensive” and Hyper-V is “free”. So how will VMware win against Microsoft? Continue reading How Will VMware Win Against Microsoft?
Data Protection and patch management of virtual desktops, while not a sexy topic, is one that should happen on a regular basis within any organization implementing or working to implement virtual desktops. Recently, we have been testing virtual desktop software and there is a huge difference between patching and protecting data in a small number of instances and 1000s of instances. There are scale considerations as well as ease of use for file level and system recovery as well as issues with patching virtual desktops (not to mention other security issues). Continue reading Virtual Desktop Patching and Data Protection
There is a dilemma for all tenants of a public or private cloud: Scope. Tenants want everything to be in scope. Cloud Service Providers (CSP) want to limit scope to the bare minimum. What does it mean for a Cloud to be ‘PCI Compliant’, and why is this a requirement for some tenants? The real issue is, what is in scope for PCI-DSS while your data is in the cloud, and how can you as the tenant meet those requirements? Remember, in the cloud, scope becomes a huge issue and a dilemma for the tenant, mainly because they may not know the scope of the cloud provider’s audit and may never find it out. So what is this scope issue and can it be fixed?

On the 4/4 Virtualization Security Podcast, Pete Nicoletti, the chief information security officer for Virtustream, joined us to discuss how VirtuStream does cloud security. VirtuStream runs some of, if not the largest SAP installations in the cloud for very large enterprises around the world. The key to VirtuStream is that they are an Enterprise Cloud that looks at everything from the Enterprise perspective, whether that is billing or security. For security, they have implemented many changes required by their customers and allowed the end-enterprise to dial that security to 11 if necessary. But what does VirtuStream do that is different from all others?
There has been a spate of press releases and news in and around the industry over the last few weeks that bear further consideration. They could actually solve some of your current cloud and virtual environment issues while opening new doors for future expansion. As an architect and analyst, I find these technologies very interesting for their possible impact on the future of virtual and cloud environment not to mention data center designs.

The software defined data center has the potential to expand the control plane well outside of anyone’s control by the simple fact that we do not yet have a unified control mechanism for disparate hardware (networking, storage, and compute), for disparate hypervisors (vSphere, KVM, Xen, Hyper-V), new types of hypervisors (storage and networking), and new ideas at managing SDDC at scale. These all end up on the control plane of a software defined data center. In addition, we cross multiple trust zones while in that control plane such as going from user controlled portals to hypervisor management constructs. Add to this the ever increasing number of APIs and we have a very hard to secure environment. Continue reading SDDC and the Ever Expanding Control Plane
