We briefly discuss the drawbacks of previous approaches to distributed computing and how they are addressed by service architectures. After presenting the basic service architecture components we discuss current Web service implementations and how grid services are built on top of them to enable the design deployment and management of large distributed systems. After discussing best practices and emerging standards for grid infrastructure we also discuss some end-user tools. We conclude with a short review of some scientific grid projects whose science goals are directly relevant to remote sensing. 183 2008 by Taylor Francis Group LLC 184 High-Performance Computing in Remote Sensing Introduction The concept of distributed computing has been around since the development of networks and many computers could interact. The current notion of grid computing however as a field of distributed computing has been enabled by the pervasive availability of these devices and the resources they represent. In much the same way that the World Wide Web has made it easy to distribute Web content even to PDAs and cell phones and engage in user-oriented interactions grid computing endeavors to make distributed computing resources easy to utilize for the spectrum of application domains 26 . Managing distributed resources for any computational purpose however is much more difficult than simply serving Web .
