Migrating to the Cloud: OpenStack or vCloud?

April 24, 2012
By
CloudComputing

We, here at The Virtualization Practice, are getting ready to have a cloud presence. Since we 'eat our own dogfood' with a 100% Virtual Environment, we are gearing up to move some of those workloads into a hybrid cloud. We already use some cloud resources, but now is the time to look at other workloads.…

Virtualization Security is NOT Cloud Security!

January 31, 2012
By

I and others look at Virtualization Security constructs with an eye towards Cloud Security, but they are not necessarily the same. Granted for some clouds, virtualization security can lead to cloud security but this really depends on how the cloud's architecture. Even so, what we know from Virtualization Security WILL apply to Cloud Security and…

Is Gluster the answer to Scalable Cloud Storage and the Amazon Outage?

Amazon failed because of simultaneous failure of its EBS in two Availability zones. If you were dependent on one of these (or mirrored across the two) you lost access to the filesystem from your Instances. It may be sensible to move to the use of the S3 mechanism (or some portable abstraction over it) for…
