Building a Management Stack for Your Software-Defined Data Center

SDDC.Management.Stack.Reference.ArchitectureData Center Virtualization has spawned several entirely new categories and variants of management software. This is largely because data center virtualization alone was a large enough change to create new requirements that legacy management products could not meet. This created a new constituency for management solutions—the virtualization team—which proceeded to purchase management solutions that met their needs. This trend was facilitated by the “easy to try and easy to buy” business model that many of the new vendors of virtualization management solutions adopted. Out of this a new management software industry arose. Continue reading Building a Management Stack for Your Software-Defined Data Center

VDI vs RDSH: Squabbling Siblings or Embattled Enemies?

PresentationVirtualizationIn many a desktop virtualization project, there will be a around the type of desktop virtualisation to use. Before you even get to the entertaining “Citrix vs VMware vs Other”  quasi-religious debate, there will be a VDI vs RDSH altercation. It can altercate for days. Ultimately, no business question gets asked, nor decision made, as technical stags lock antlers. It is not unusual for this debacle to be silenced by someone simply getting tired of the PoC posturing and rolling out pallet loads of new PCs.

If any year is to be the year of virtual desktops, then it is not just simply a question of having nifty appliances, but also of having a better understanding of desktop virtualization solutions. A recent article from the BBC website on common language gave the ultimate benefit of a common understanding as “world peace”. If a better understanding between people can bring the laudable hope of goodwill unto man, then surely an easier corporate upgrade and better application access will be a mere bagatelle?

The options for purchase for VDI or RDSH, VDI or Terminal Services, for hosted desktops or session desktops are all the same conversation. RDSH is indeed on the back foot through regular re-marketing of terms. Presentation Virtualization Terminal Services and RDSH are the same thing: a multi-user server OS capable of hosting applications and desktops to remote users.

Increasingly, desktop virtualization vendors are ensuring they sit between both VDI and RDSH camps. Citrix obviously – XenApp and XenDesktop.  In our Presentation Virtualization whitepaper, every RDSH vendor has a VDI option. But also, “traditional” VDI vendors are being more savvy. Desktone offers a RDSH option. Teradici has delivered on their promise and recently announced Teradici Arch, a software solution for RDSH.

What are the similarities and differences between VDI and RDSH? What can calm everything down and make the combatants think about what it is that they have done?

Are Things Becoming too Automated?

DataCenterVirtualizationAre things becoming too automated? That is a question I cannot believe I am asking. I have spent most of my virtual career creating automated processes from my virtual environments. I spent a great deal of time creating a “toolbox” of scripts to perform almost all of the tasks that I found myself needing to do in an automated fashion. A lot of my peers and I were all creating automated build and automated configuration of our environments from the very beginning and now are seeing a great deal of the automation that we created in one way or another being added to the product suite. Is that a bad thing? No, on the contrary, this shows the active deployment of the technology and gives us insight to the direction the technology may follow.

Public Cloud Reality: Cloud Application Performance Management is your problem

PerformanceManagementThe Virtualization Practice is in the middle of physically moving our data center servers from one city to another. Since it proved impractical to keep them online while they were on the moving van, we moved the web site to a public cloud until we could rebuild our data center in our new location. We encountered several interesting issues with public cloud computing in this process. Continue reading Public Cloud Reality: Cloud Application Performance Management is your problem

Public Cloud Reality: Application Security is in your Hands

VirtualizationSecurityWe recently moved workloads to the public cloud and the public cloud reality does not match the hype, nor does it match the application security requirements of a small or even large organization. There are two sides to the public cloud security discussion, the one that covers management access and the other that covers application security. For the former, you must trust the cloud, however for the later, you basically get the security you bring to the cloud. The public cloud reality is that you do not magically gain application security when using a cloud. Continue reading Public Cloud Reality: Application Security is in your Hands
