Online stores are the new, next-generation, "revolutionize the world as we see it today" way of doing business. In the context of business transactions, online stores use the global Internet to facilitate purchase and sale of goods and services. The ability to support online sales is an essential component of the new e-commerce paradigm for Internet-based businesses today. Putting together an enterprise-level application for an Internet store involves design and integration of various technologies that play specific roles in a distributed computing environment. A distributed topology is a prerequisite for building such Internet applications since the Internet is inherently distributed in nature. Due to the plethora of alternative technologies available in the computing arena today, designing an enterprise application involves choosing between technologies based on f... (more)

The Digital Consumer: Big-Data-Enabled-Cloud's Final Destination

I used to be a regular presenter at SYS-CON's tech.conferences. After a hiatus of a few years, I thought of presenting at the Cloud Expo conference in New York. I was wondering which track to participate in.

I have helped incubate one of the strategic focus areas within Infosys - digital transformation, which is powered by Cloud. The a... (more)

Java in the Middle Tier

This month the Java platform segues into the new millennium. These are very exciting times; 1999 was a crucial year in the acceptance of Java in the enterprise as one of the key drivers of e-business.

During the year gone by, the focus was on server-side Java, as predicted last year by several industry pundits ­ more precisely, on Java in the middle tiers of distributed computing.... (more)

J2EE Design Patterns: The Next Frontier

We live in a world where abstraction is the name of the game. I used to be an avid reader of Asterix comics, and thinking of abstraction reminds me of a couple of panels in the "Obelix & Co." comic book. A Roman emissary tries to explain to the (simpleton) Obelix the intricacies of Roman economy in simple words: "Make much menhir, get much gold," or something to that effect. I don't mean to say that we developers are simpletons. But, as my colleagues in marketing say, the presentation needs to be "dumbed-down" for the appropriate crowd. As an enterprise architect, I don't want to ... (more)
