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." Scalability in a system is about the ability to do more, whether it is processing more data or handling more traffic, resulting in higher transactions Scalability poses great challenges to database and transaction systems An increase in data can expose demand constraints on back-end database servers This can be a very expensive and short term approach to ...

Is Cloud Computing Just Virtualization and Automation? No!!

Day and day out, we see every technology vendor attempting to position themselves in the cloud realm and struggling to find a niche in this 'cloudy' topic. I think: 1. Virtualization and Automation are the building blocks of the cloud computing platform. They alone will not solve any problems. 2. Cloud computing is based on the premise that it is a new model that accommodates a new services delivery and consumption model. Now the term 'service' is very elusive, and I think this is what it is exploited by every vendor trying to find that 'fit'. 3. Without a vision and a set expe... (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)

Apache Hadoop and WebSphere eXtreme Scale

Hadoop Apache Hadoop is a software framework (platform) that enables a distributed manipulation of vast amount of data. Introduced in 2006, it is supported by Google, Yahoo!, and IBM, to name a few. At the heart of its design is the MapReduce implementation and HDFS (Hadoop Distributed File System), which was inspired by the MapReduce (introduced by a Google paper) and the Google File System. MapReduce MapReduce is a software framework introduced by Google that supports distributed computing on large data sets on clusters of computers (or nodes). It is the combination of two pro... (more)
