First, let's look at the three major virtualization vendors to see what they have been up to over the past several months:
Also in the first half of this year they put out an iPad version of their View virtual desktop app and released version 7 of its email software Zimbra.
They released a bunch of scripts to help troubleshoot XenServer and boosted the feature set in a new v9.3 of NetScaler Firewall. Finally, they recognized that Amazon's Web Services (AWS) is an important place to provide integration with its Xen lineup, since, after all, Amazon makes use of Xen to provide its many services.
Speaking of AWS, perhaps the most notable event of the past several months was a major outage there caused by a router mis-configuration. The outage rippled through sites that use AWS for their operations, including Quora, Foursquare and Reddit, and was a good lesson to understand what your cloud provider can and can't do in terms of providing failover operations.
Dynamic memory allows for memory on a hypervisor to be pooled and dynamically distributed to virtual machines as needed, all without interrupting services to the VMs. There have also been additional improvements to enhance scalability and high availability when using DirectAccess in building large server networks.
One of the ways around the issues of security and control that make some businesses wary of cloud computing is to build a private cloud -- one that remains within the corporate firewall and is wholly controlled internally. Private clouds also increase the agility of IT an organization's IT infrastructure and make it easier to roll out new technology projects.
