Reuven Cohen's "ElasticVapor" Blog Over the last few weeks I've been engaged in several conversations about the need for a common, interoperable and open set of cloud computing standards. During these conversations a recurring theme has started to emerge. A need for cloud interoperability or the ability for diverse cloud systems and organizations to work together in a common way. In my discussion yesterday with Rich Wolski of the Eucalyptus project he described the need for a "CloudVirt" API similar to that of the Libvirt project for virtualization. For those of you that don't know about libvirt, it's an open source toolkit which enables a common API interaction with the virtualization capabilities of recent versions of Linux (and other OSes). I would like to take this opportunity to share my ideas as well as get some feedback on some of the key points I see for the cre... (more)

Virtualization Is Not Cloud Computing

Reuven Cohen's "Elastic Vapor" Blog Recently I've been frequently asked; "Is virtualization...cloud computing?" So this next bit may sound a little odd coming from someone who has built a cloud computing platform on the basis of server virtualization. Although virtualization is an ideal building block for a cloud environment, saying that "virtualization" is the only basis for cloud computing is wrong. Notably Google uses little to no virtualization technology and is seen as the poster child for the cloud computing movement. They recognized that cloud computing is about the move ... (more)

Cloud Computing Viewpoint: Is Salesforce For or Against Vendor Lock-in?

Reuven Cohen's "Elastic Vapor" Blog It's been an interesting week for Salesforce.com Chief executive Marc Benioff. The Salesforce chief called for the creation of cloud interoperability standards for moving data between applications in rival clouds. Which on the surface appears to great step forward. Problem is he was very quick to contradict himself. Marc's stance on cloud interoperability is almost as confusing as trying to follow the recent back and forth between Hugh MacLeod, Nick Carr and Tim O'Reilly's wildly crazy epic on cloud monopolies. It's been an interesting week for... (more)

Semantic Cloud Abstraction

The CCIF and it's members have recently focused on creating a common cloud taxonomy and ontology. I find it's starting to sound a lot like semantics, Cloud Semantics. We are in a sense defining what cloud computing is by describing it's "components" and their relationships to one another. One that is capable of expressing cloud computing and its subsequent parts in terms of a consensus data model. So in this effort we may actually be defining a dynamic computing model that can, under certain conditions, be 'trained' to appropriately 'learn' the meaning of related cloud & infrastr... (more)

VMware's vCloud API Still Hazy, Ambitions Are Clear

VMware continues to make noise around its forthcoming vCloud API initiative. According to an announcement last week VMware has developed a new API aimed at offering service providers with the ability to easily migrate between public and private VMware-based clouds. Like the previous announcement, details are sketchy other than to say "select group" of partners are using it. When asked to comment or share a copy of the vCloud API, the companies involved indicated they were covered by an NDA. Those companies include SAVVIS, SunGard, Telefonica, Telstra and Terremark. According to m... (more)
