The term GRID started in the mid 1990s to describe a distributed computing structure for scientific research (in particular on the field of particle physics). The concept underlying the GRID technology is co-ordinated resource-sharing and problem-solving in dynamic, virtual organisations. Today GRID technology is encroaching on a spectrum of new application fields such as meteorology, biology and also medicine. Health GRID isintelligent and innovative use ICT in order to support broad access to rapid, costeffective and high quality healthcare. GRID Computing wants to provide a global ICT infrastructure that will enable a coordinate, flexible and secure sharing of diverse resources, including computers, applications, data, storage, networks and scientific tools acoss dynamic and geographically dispersed organizatives communities (so called Virtual Organizations). As WWW transformed the way we exchange information, GRID concept takes parallel and distributed computing to the next level, providing an unified, resilient and transparent infrastructure, availableondemand in order to solve increasingly complex problems.
