Quite honestly, I am a little fascinated at the preponderance of focus the industry sometimes puts on the cloud attribute of elasticity. Sure, it is important, and in fact, a necessary attribute to truly consider something a cloud. It also makes for cool reading in case studies where companies have successfully harnessed elasticity in the cloud to reap business value. However, in my experience with enterprise users, many would benefit from a couple of less sexy, but equally important attributes of cloud: standardization and automation. When I am out talking with middleware application users (administrators, developers, operators, etc.), I hardly ever pass up the opportunity to ask ‘What are your biggest pain points?' While I sometimes get answers that indicate the need to more effectively and rapidly scale systems up and down, those pale in comparison to the number... (more)

Something You May Not Know About IBM and Cloud

Ask someone to associate IBM and cloud computing, and that person will probably come back with something about solutions to help build private clouds. I know because I ask... all the time. On the surface, this is a fair association. After all, it is true that IBM offers quite a few different solutions that help users to build both private clouds and on-premise clouds that they then offer up to others (i.e. enabling service providers). However, it does not participate in this cloud delivery model at the expense of other delivery models. In fact, IBM has a wide-breadth of cloud so... (more)

Introducing WebSphere CloudBurst 1.1

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 con...

Declarative Programming in the Cloud

Earlier today I read an interview with fellow IBMer Andrew Spyker that touched on the use of declarative programming models in the new WebSphere XML Feature Pack. I think most of you are probably comfortable with what a declarative programming model is, especially in comparison to imperative programming models, but I really like Andrew's explanation in the interview: ... declarative programming asks the user what they want to do. This is as opposed to imperative programming (ex: Java code working with the DOM or JAXB APIs) which asks the user how they want to do what they want to ... (more)

What Does Elastic Really Mean?

Normal 0 MicrosoftInternetExplorer4 In terms of cloud computing in application environments, elasticity is perhaps one of the more alluring and potentially beneficial aspects of this new delivery model. I'm sure that to many of those responsible for the operational and administrative aspects of these application environments, the idea that applications and associated infrastructure grows and shrinks based purely on demand, without human intervention mind you, sounds close to a utopia. While I would never dispute that such capability can make life easier and your environments muc... (more)
