The Virtualization Practice

Tag Archive for VMotion

On 9/8 was held the Virtualization Security Podcast featuring Phil Cox, Director of Security and Compliance at RightScale, to discuss the impact of and need for automation of cloud security. Given that we create clouds by automating deployment of workloads we also need to automate the security of those workloads during the same deployment. This podcast delves into that need, and touches on where over automation is also a problem.

Chad Sakac mentions on his blog that VNXe “uses a completely homegrown EMC innovation (C4LX and CSX) to virtualize, encapsulate whole kernels and other multiple high performance storage services into a tight, integrated package.” Well this has gotten me to thinking about other uses of VNXe. If EMC could manage to “refactor” or encapsulate a few more technologies, I think we have the makings of a killer virtualization security appliance. Why would a storage appliance spur on thinking about virtualization security?

The question of whether and how to replace DRS is really a part of the question of what is in the virtualization platform and what is not. Clearly the virtualization platform consists of much more than the hypervisor. VMware would like to define the virtualization platform as all of vSphere Enterprise Plus, and then suggest that vCloud Director and its own performance management solutions are logical extensions of that platform. Enterprises need to be careful about where they draw their own lines in this regard. As VMware is a clear market leader both in terms of product functionality and enterprise installations, VMware needs to be given full credit for the quality of vSphere and its success. However full credit does not need to imply that one is 100% locked in to VMware solution as there is room to pursue third party IT as a Service, Performance Management, and Service Assurance strategies as well as replace/augment components in vSphere.

vSphere 4.1 Released – More Dynamic Resource Load Balancing

With the release of vSphere 4.1, VMware has added to their Dynamic Resource Load Balancing (DRLB) suite of tools that I hinted at in my post on Dynamic Resource Load Balancing that I wrote last week as well as providing new memory over commit and other functionality. In essence, vSphere 4.1 is more than a point release, this update includes many features that aid in security, reliability, and is a direct response to customer requests.
