Performance analysis in loosely-coupled distributed systems

摘要: A great deal of work is currently underway to develop infrastructure for supporting a loosely-coupled computational model over the Internet. This based on standardization Web Services interfaces and protocols allow application-to-application communication interoperability using XML messaging[1]. An example an existing Service Google search API programmatic access Google’s service[2]. Another Microsoft Passport which maintains online identity users that can be accessed by other applications purposes authentication[3]. With introduction comprehensive standards, it expected will become more common. Consequently deployment aspects remain significant challenges service provider need addressed, including, among others, performance, configuration, management, security dependability. paper considers some performance-related issues must tackled in order potential provide truly global distributed system achieved.
