The requirements for a Service Oriented Architecture (SOA) Infrastructure are:
Availability : Process and service isolation from hardware and communication failure. Distribution : Process interaction with services located within the enterprise as well as outside. Flexibility : Modification of processes, relationships between applications, rules, data mappings, etc. with minimal effort and downtime. Heterogeneity : Loosely coupled architecture consisting of both existing legacy applications and new service-enabled applications. Scalability : Enterprise system-level performance ready to accommodate on-demand changes. Visibility / Control : Auditing, managing and monitoring of processes and services deployed.
