The Virtualization Practice

Agent and Agent-less Backup in the Virtual Environment

There is some debate amongst backup vendors on what defines an agent, some consider any amount of scripting to be an agent, while others imply it is what does the data transfer plus any amount of scripting necessary. Is there a need for both Agent and Agent-less within a virtual environment? This also begs the question, who is responsible for properly handling the application whose data you are backing up?

The week before VMworld on 8/25 was the Virtualization Security Podcast featuring Greg Ferro (@etherealmind), CCIE to discuss Cisco VM-FEX and its impact on virtualization and cloud security. VM-FEX is a method by which the fabric of a UCS top of rack switch is extended to the VM, but only if the VM is using VMDirectPath. So does this impact Virtualization and Cloud Security in any way?

Secret Shopper Report – VMware CloudFoundry

To recap the story so far, I’m prototyping an application and deploying it to various PAAS environments. I am not getting any special help from any of the vendors in this exercise – you can think of me as a “secret shopper” for PaaS, although I don’t hide my identity. I am approaching each platform on its own merits, and in these posts I am recounting and contrasting my experiences and reaching some general conclusions about the PaaS market.

VMware Articulates a Compelling Management Vision – Automated Service Assurance

VMware deserves an enormous amount of credit for promising to reinvent IT Operations around automation and the guaranteed performance of applications. VMware either has or is working on all of the building blocks required to execute upon this vision for the vSphere platform. The combination of innovation by VMware, and by the third party ecosystem on this front will create a new compelling benefit to virtualization, that will allow virtualization to comfortably address business critical and performance critical applications.

If there was one thing I saw and heard about at VMworld, was the number of third party collaborations that were taking place. While not explicitly stated by VMware at VMworld, the show floor had many different collaborations that were taking place. This level of collaboration shows a level of maturity within the virtualization and cloud vendor ecosystems. A maturity, that shows that the vendors understand the benefits of leveraging other companies to lower their overall costs while producing better and more attractive products. Some of the collaborations I saw where purely the resale of products, while others were integrations between products.

VMware announced a loosely coupled group of vCloud providers that will use vCloud Connector to loosely couple their clouds, so that VMs can move from vCloud to vCloud without requiring you to renegotiate pricing, capability, and functionality with multiple cloud vendors, just your local one. This announcement is intriguing in that it is a move to push the cloud into the global space, but also fraught with peril if not done correctly.

The challenge for Citrix is to position their VDI portfolio effectively. At the very least there should be a standardised license plan and migration path from (or to) the grid and non-grid solutions. There is potential to remove the reduced functionality versions of XenDesktop. Most importantly – to have a license model that allows organisations to make a choice of technology that fits their need, not their size. Can Citrix FlexCast be truly flexible if it ignores the value that having a grid technology can bring not only to the SMB market – but to any sized enterprise?
