Adoption of XTP (eXtreme Transaction Processing) leveraging grid-enabled Federated Enterprise Service Bus
Shivaji. Sarkar, Peter Mendis · 2011
predicts that By 2011, more than 20% of new TP application projects will require support for more than 10,000 concurrent accesses or more than 500 transactions per second, up from less than 10% in 2006 (0.7 probability). To avoid vertical scaling on expensive and proprietary hardware and software, eXtreme Transaction Processing applications are architected to scale horizontally to minimize initial deployment costs and optimize the cost of scaling up. One such foundational technology for XTP is Enterprise Service Bus (high-performance interaction with distributed resources) given the distributed, service- oriented and event-driven nature of most new transactional applications. However, the shortfall of scalability and performance even with the combination of Enterprise Application Servers (EAS) and ESB technology to meet the requirement of the most extreme scenarios, forces enterprises to adopt incremental (Computing Appliances e.g. Xi150) and emerging technologies (Enterprise Grid Architectures) without forcing substantial application redesign. This article aims to establish the options of adopting the optimum solution for eXtreme Transaction Processing leveraging service virtualization, federated enterprise service bus and grid-architecture.
