Grid computing has been considered a professional technology, but from the most recent development boom, the "application" of mensheng is the most suitable for service is the next generation of applications in the industry - Web services, and becomes SOA pillar technology. Naturally, I am going to enter the corporate environment with my grid, and the idea and argument of her application potential seem to never stop. After the grid is installed, the company's network executives will find that this technology can not only calculate the intensive tasks, but also apply to a variety of applications. Grids can also easily handle high transaction volume or data-intensive application. For users who were earlier in this technology, they were a very powerful next-generation application server, and they were relatively high. Ortega, a vice president of architecture and engineering, pointed out: "More than 700 nodes in our grid constitute virtual application servers, including Windows, Linux, and Solaris / Sun applications. We also have a dedicated application server, but plan Use grid to replace expensive Sun platform servers. "Facts prove that grid is the most suitable" application area "of the most suitable service is the next generation of application -Web services. Peter Lee, CEO of DataSynapse, Grid Middleware, is obviously impossible to transplant the entire enterprise to SOA, and reasonable solution is to let each application software or service run in its own independent environment. Let the grid depend on the service level to allocate hardware resources. Therefore, to implement SOA, the grid is a logical pillar technology. "ORTEGA also agreed to this point. He said: "Initially, the grid is only used to calculate the intensive application software, but now we are positioned as a universal trading environment." Wachovia built its own grid system in 2002, using Datasynapse software, Since then, multiple risk analysis, securities prices, and other applications are used to perform multiple risks. Ortega said that the work to be completed in the past is only 15 minutes. Last year, some IT executives extended the application of the grid and finally developed into a SOA platform running a variety of web services. For example, Wachovia is running so-called "Convert" Web Services on the grid. These transaction information must be converted from a format to another format or converted to a format suitable for application rules. ORTEGA uses web services as middleware between APIs. For example, when an application needs to convert data to a Java JAR file or Windows DLL, by using a web service, data can be converted from a private application to another without having to customize the API. And because Wachovia's system can handle approximately 5,000 conversion information per second, almost unlimited processing capabilities in the grid make this application software design easily. He said: "For each person who wants to establish a J2EE application server, the grid is ideal, it does not differ from the standalone server. Virtual makes the application software will not connect to a specific hardware, and only connect Go to an abstraction layer. "This abstraction layer is Datasynapse software that can assign workloads to each available CPU in the grid and is responsible for collecting results and returning them back. ORTEGA's final concept is to build this application server based on the basis of WACHOVIA public computing facilities, thereby converting IT departments into service providers, so that each department only pays corresponding costs for their own calculations. Foster is the Argonne National Lab Grid Technical Director, and is also the founder of the 2005 Emerging Grid Service Enterprise-UIVA. He is considered to be a top expert in the field of grid computing.
