Emerging Trends in IT

Present trend in Information Technology are Grid Computing and Service Oriented Architecture (SOA).

Grid computing uses technology related to cluster computing. Cluster computing is a tightly couple system with single image (combination of node under one roof) and centralized job management & scheduling system. But, Grid computing is loosely coupled system with distributed job management & scheduling system. Basically, grid computing is superset of distributed computing and it is a combination of many clusters or nodes under globe.

Service oriented architecture (SOA) is a collection of services which are inter connected. SOA facilitates development of modular business service that can be easily integrated and reused. It helps users build composite applications, which are applications that draw upon functionality from multiple sources within and beyond the enterprise to support horizontal business processes.
