While the press and blogs are buzzing about cloud computing, VMware has made probably one of the most significant cloud-related announcements ever made; and with : vShield Zones has added even more distance between rivals when it comes to data center and cloud security. Last year at VMworld in Cannes, VMware announced the VMsafe VMware security partner ecosystem. The virtualization security "industry" had been notably silent (other than a colorful row between security blogger/expert Chris Hoff and Citrix CTO Simon Crosby) for the rest of 2008. Virtualization expert Rich Miller even mentioned the sound of security silence at VMworld Las Vegas in September: The theme I noted most at VMworld 2007 a year ago was "security."  This year, it seemed noticeably absent.  My sense is that the industry has yet to catch up and capitalize on VMsafe. Because all of the "next gene... (more)

Nick Carr's Cloud-Network Disconnect

Virtualization and cloud computing are promising to change the way in which IT services are delivered and, in effect, transform computing as we know it today.  I think the promises are likely to come true, if and only if critical technology issues are addressed. Nicholas Carr told a recent audience at IDC Directions that "Cloud computing has become the center of investment and innovation."   While he is not a technologist, his sometimes shocking insight into the transformation of IT have been prescient, even if he doesn't sweat the details of how complex IT infrastructures can mo...

Specialty Cloud and the Rise of the Green Data Center

Last week I had a brief meeting with Yoram Heller of hot cloud player Morphlabs and we talked about the next wave of cloud innovations.  Of particular interest was the concept of specialized software suites that ride on top of the commoditized cloud platforms that have so far captured most of the popular interest in cloud computing. It is possible, if indeed likely, that most forms of dedicated hardware or appliances in the network will be replaced by powerful instances, workloads and or/ boutique platforms that transcend the physical and technical boundaries that have been in p...

Outages and the Weakonomics of Public Cloud

The latest Amazon outage again begs whether or not Amazon’s customers are technology leaders or laggards simply trying to reduce IT costs to their bare minimum.  Certainly some enterprises are properly using the public cloud for key projects where a non-critical application or service needs to be created quickly and within a low budget.  Yet some companies seem to be using the public cloud for even predictable workloads, with the idea of minimizing costs even to the point of accepting higher risk.  This comment from Michael Lee at ZDNet: “What this has means, though, is that sever...

Are You Stuck in a Cloud?

Today public and private cloud operating models offer islands of IT operating efficiency that can be highly desirable for applications and services specifically designed for the cloud or which are already virtualized.  Yet for the vast majority of multi-tier applications the cloud is still a pipe dream of promises and expectations.  The problem isn't with the cloud service providers per se, but rather with the vast gulf of manual processes required to migrate and operate apps (and their services) into and between data centers, colocation facilities and various public clouds.
