Introduction As the IT operations continue to evolve and transform the business towards agility and adaptability to ever changing rules of marketplace, the efficiency of any IT operation is of paramount significance. The phrase ‘time to market' has a completely new meaning in today's dynamic business environment where the only constant is change. This rapidly changing environment has lead the IT and business leaders alike to re-think the ‘procurement to provisioning' process with one goal in mind - Efficient use of resources. These resources include IT assets such as hardware and software, human capital such as administrators, developers, testers, other IT management staff and facilities employed in hosting the overall IT infrastructure. The efficiency goals are not only towards costs savings but also are defined by the business requirement usually driven by exte... (more)

IBM CloudBurst and WebSphere CloudBurst Appliance Compared

What is a cloud computing platform? Is it simply automated provisioning systems coupled with a resource virtualization, where the workload is policy driven, and resources over committed and any resource contention handled by policy driven resolution? As it turns out technologies that provide provisioning, virtualization and policy enforcement form the building blocks of a true cloud computing platform, but not any one technology is a cloud offering in and of it self. IBM’s CloudBurst family attempts to provide a single cloud solution with an appliance form factor. This paper will... (more)

The Changing Landscape of Middleware

Lately I have been engaged with many clients that are maniacally focused on reduced costs by means of reduced footprint. In this post, I attempt to discuss some of my thoughts and experiences towards this trend: Growth poses a problem: As business grows so does the resulting infrastructure and primarily the middleware which houses the business logic and in some cases this tier shares the presentation or the store front with business logic. So with growth in business either due to larger client base or new business model implies similar growth in middleware. This consistent growt... (more)

Scalable HTTP Session Management with WebSphere Extreme Scale (WXS)

HTTP session management is a function offered by Java Enterprise Edition (JEE) application servers. It allows JEE applications to store state information about a given user across many HTTP requests. The JEE specification provides an API to store and retrieve information specific to the given user. WebSphere application servers and other competing products, provide session replication functionality. This is normally done either by writing to a database or through memory-to-memory replication technology.  These approaches while extensively used today, have operational challenges ... (more)

WebSphere eXtreme Scale Design and Performance Considerations

Fundamentals: How does WXS solve the Scalability problem? Understanding Scalability In understanding the scalability challenge addressed by WebSphere eXtreme Scale, let us first define and understand scalability. Wikipedia defines scalability as a "desirable property of a system, a network, or a process, which indicates its ability to either handle growing amounts of work in a graceful manner, or to be readily enlarged. For example, it can refer to the capability of a system to increase total throughput under an increased load when resources (typically hardware) are added." Scalabil... (more)
