The demand for reliable, high-performance Online Transaction Processing (OLTP) systems has been skyrocketing in recent years as more and more people migrate to the Web for services that formerly needed face-to-face interaction as well as geographical and temporal proximity. Whether renewing vehicle registration, purchasing books, participating in online communities, or collaborating in global projects, users expect online services to be available and responsive, no matter when or from where they are accessed. Sun systems with CoolThreads™ technology deliver scalability, high reliability, and breakthrough OLTP performance. This helps ensure that organizations using these systems deliver the best possible customer experience while at the same time minimizing their administrative overhead and reducing costs.
