Earlier this month I attended the IBM Impact conference in Las Vegas.  The core theme of Impact was "Smart SOA" and how cloud computing comes together in the enterprise, with the emphasis on private clouds.  The core notion of private clouds for IBM is really about extending their experience in virtualization, which is vast, into the more modern world of cloud computing.  They hope to sell some hardware and software in the process.  IBM considers private clouds strategic to its platforms.  The movement to private clouds plays right into its hands.  Recently they are announced a new software appliance called IBM WebSphere CloudBurst Appliance which is "A secure appliance that provides speed and repeatability for deploying WebSphere environments into a private cloud."   Or, we can call it virtualization-in-a-box, to be more accurate. IBM and many others define private... (more)

Real-World AJAX

So, what do AJAX and SOA have in common? The answer: Everything. Is AJAX an enterprise technology? The answer: Absolutely. As we move to next-generation enterprise architectures using newer notions such as Service Oriented Architecture (SOA), there's a need for a dynamic Web interface that can layer over services and provide more value to the enterprise. Moreover, the enterprise in general can benefit from the advantages of AJAX; it's just a matter of making enterprise developers as well as the SOA architects aware of AJAX. AJAX is becoming the standard dynamic interface for the W... (more)

The Realities of Cloud Computing

I’m just finishing up a book on cloud computing and SOA, and found the process of writing the book to be a great catalyst for thinking through the issues surrounding cloud computing, as well as assisting my clients with their cloud computing strategies. As I found, there are a few issues to consider with cloud computing: First, cloud computing is not the savior of IT. It’s nothing but a way to deploy your enterprise architecture in such as way that has the potential to be more productive and cost effective. In essence, it’s a tool, not a way of life. It’s not magic, it’s not even... (more)

Leveraging Web Services for Application Integration

Web services holds the promise of moving beyond the simple exchange of information - the dominating mechanism for application integration today - to the concept of accessing application services that are encapsulated within old and new applications. This means organizations can not only move information from application to application, but they also can create composite applications, leveraging any number of back-end application services found in any number of applications, local or remote. Key to this concept is figuring out how Web services fit into the existing application int... (more)

Is Your Client Rich?

As we look to make more practical use of Web services, the need has emerged for a better user interface; one that's neither too fat nor too thin. An interface that allows developers to make the most out of the client's native features, while at the same time, not bogging the client down with services that are better kept at the back end. We call this new hybrid interface a rich client. A rich client is a small piece of software that runs on the client to leverage and aggregate back-end Web services, allowing them to appear as a single, unified, native application. Indeed, a new ...
