Welcome
Introduction
Service oriented architecture (SOA) is a conceptual description of the structure of a software
system in terms of its components and the services they provide, without regard for the
underlying implementation of these components, services, and connections between components.
Loosely coupled integration applications that are based on SOA provide flexibility and agility
Performance modeling of SOA-based workloads is of particular interest because of certain
characteristics of such workloads:

Performance modeling of SOA-based workloads is of particular interest because of certain
characteristics of such workloads:
- SOA is often deployed to build business-critical applications. Serious considerations need to be put into response time/scalability.
- SOA workloads can be distributed. The implication of this is that the impact of any performance issue will propagate.
- SOA workloads can be dynamic and heterogeneous. The implication of this is that one might never have enough empirical data to help predict the performance of an application. What would help is a modeling tool that has built-in probability models.
