IBM Journal on Ulitzer I've written numerous technical entries both here and elsewhere about the WebSphere CloudBurst Appliance. The appliance is a cloud management device that is geared towards those enterprises that for a variety of reasons (security, privacy, performance, customization capability, existing investment, etc.) are looking to benefit from on-premise or private clouds. The initial version of WebSphere CloudBurst, released in June of 2009, introduced the capability for you to create, deploy, and manage WebSphere application environments in a cloud that they retain control over (you can read a short article about the 1.0 version of the product here). While that may seem straight forward enough, this can radically change the way you come to perceive your application environments. By using this appliance-based approach, you can achieve flexibility and agili... (more)

IBM & Cloud Computing: Self-Service Clouds with Fine-Grained Control

A common feature of cloud computing solutions is that they enable self-service access to the services they provide. This enables users to directly procure services from the cloud, and it eliminates the need for more time-consuming, labor-intensive, human-driven procurement processes familiar to many in IT.  That's not to say that a cloud computing solution should provide its services in a free-for-all manner, letting any user take any action within the system. There should be strict controls over the services users have access to and the actions they can perform with those servi... (more)

An Application-Centric View of Cloud Computing

A recent survey from F5 indicates that the cloud computing movement is making significant headway despite what some may see as mere fluff and hype. The survey, comprised of employees from large enterprises (2500+ employees), indicated that 82% of respondents are in some stage of public cloud use/trial and that 83% were in some stage of private cloud use/trial. Apparently, at least for the respondents in this survey, cloud computing has officially arrived. If we are to believe that cloud computing adoption is on a serious up-tick, what should we look to as the next wave or focus in ... (more)

Cloud Computing and Virtual Images

Cloud Expo on Ulitzer A look at several different cloud computing solutions will reveal a technological enabler present in almost each one. The enabler I'm talking about is the use of virtual images. I cannot think of many, if any, cloud computing solutions that provide software elements (i.e. more than just servers, storage, memory, etc.) that do not use virtual images in some form or fashion. Of course, one of the reasons virtual images form the backbone of many cloud solutions is obvious. Virtual images provide the benefits of server virtualization. We can activate many virt... (more)

Standardization and Customization in the Cloud

Maybe it is a misunderstanding, misperception or a myth, but it seems quite a few people make an incorrect assumption about standardization and customization when it comes to services delivered in the cloud. Specifically, the message I hear often from both providers and consumers seems to pit standardization and customization against each other, almost as if you can only have one or the other. This, of course, is wholly incorrect. Seemingly, a lot of the confusion in the standardization/customization arena comes from the rhetoric often delivered around the different cloud delivery... (more)
