My money is on the Suites

About two months ago, I contacted a number of CIOs from large firms about their recent SaaS (Software as a Service) implementations. One of the things I heard from several of these executives was that they would implement more SaaS products only when SaaS vendors develop more applications. Why? These software buyers want an integrated suite of products and not have a bunch of best of breed SaaS applications that the customer must integrate.
Integration in the SaaS world is different than what one finds in the on-premise world.

Dell Corporation (Thailand) grasps the opportunity of virtualisation and cloud computing trend to pioneer launch its broad portfolio of Software as a Service (SaaS) applications through cloud-based services.

According to Anothai Wettayakorn, Dell Thailand managing director, technology has transformed from mainframe to mini computer, PC and client server, Internet to today's era of virtualisation and cloud computing where it's no longer an option, but is a must.

Citing Merrill Lynch, Anothai said cloud computing will triple by 2012, with current worldwide spending of around $42 billion, or 25 percent of overall IT spending, increasing to $95 billion in 2015. The growth of cloud computing in Thailand will coincide with the global trend.

On the face of it, business process management (BPM) and Software as a Service (SaaS) seem like the ultimate power couple. Each succeeds at bringing more agility and productivity to businesses and business process management systems, and SaaS can make sure resources are deployed efficiently. But integration and some centralized control are key to making BPM as a Service work.

"Due to the nature of our economy, business processes need to be adjusted on a more regular basis," said Jeff Kaplan, founder and managing director of ThinkStrategies Inc., a consulting firm in Wellesley, Mass. "Legacy systems are cumbersome and not designed for that continuous change."
