BigData (and Hadoop) are buzzword and growth areas of computing; this article will distill the concepts into easy-to-understand terms. As the name implies, BigData is literally "big data" or "lots of data" that needs to be processed. Lets take a simple example: the city council of San...
This is the third episode of the mini-series on e-commerce performance management. Our client TescaraHats (name changed for commercial reasons), a European market leader in manufacturing customized hats, did not achieve the expected sales increase with its new e-commerce site. It offer...
Knowing what Big Data is, is one; knowing what a Big Data strategy is two; knowing how to implement that Big Data strategy is even more difficult. At least, that is how a lot of organizations perceive it. It must be said, in large process-directed organizations, what most of the large ...
In my recent article, "Five Steps to Improve E-Commerce Performance for Increased Sales: Introduction” I discussed problems encountered by our client TescaraHats (name changed for commercial reasons), a European market leader in manufacturing customized hats. The company quickly realiz...

Complexity is the new reality of web and mobile applications with almost no new release going out without the addition of services and applications spread across many different companies. But the reality of this new interrelationship is still the same: If a third-party Internet outage ...
The saying “if it doesn’t exist on the Internet, it doesn’t exist”[1] is ringing truer every day. Nowadays, it is hard to imagine most businesses without an e-commerce platform, let alone without a web presence at all. Since e-commerce is becoming the new standard, e-commerce performan...
Cloud service providers store data all over the globe, and are constantly moving that data from one datacenter to the next for reasons as wide-ranging as cost considerations and redundancy requirements. Does this mean that the requirements outlined in varying data residency laws and pr...
Software-defined networks are all the rage these days – and why not? They offer the promised benefit of making networks far more agile and responsive to dynamically changing application requirements. Consequently, in theory, the entire networking-computing-storage-applications ecosyste...
