Are the Cloud Bambies Waking Up to Enterprise Requirements?

DataCenterVirtualizationGoogle has delivered live migration in its Google Compute Engine cloud offering. Now comes word from Barb Darrow at Gigaom that Amazon is working on live migration as well. Is it possible that the cloud bambies are waking up to the fact that not all applications are stateless and that for many applications, shutting down instances is simply unacceptable? Are the cloud bambies waking up to enterprise requirements for availability and performance management?

Automating Cloud Security

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. Continue reading Automating Cloud Security

EMC VNXe Spurs Thinking Outside the Box

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? Continue reading EMC VNXe Spurs Thinking Outside the Box

Replacing DRS – With What and Why?

DRS is one of the most useful and interesting features of VMware vSphere (to be more specific – feature of versions of vSphere from Enterprise on up). DRS is useful because it prevents workloads (VM’s) that are consuming more than the expected amount of resources, from potentially harming the performance of their neighbors in the same host with this “excess” resource consumption. DRS is interesting because the idea of dynamically balancing the load of a system in order to ensure the performance of the critical workloads running on that system is something that was taken for granted in the days of the mainframe, but has not as yet been well implemented on distributed Intel architecture systems.

vSphere 4.1 Released – More Dynamic Resource Load Balancing

With the release of vSphere 4.1, VMware has added an impressive set of new features. These generally fall in the areas of improved manageability, improved performance and improved scalability. 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.
