This paper discusses successful operational management of the emergent technologies represented by the adoption of Web Services for application integration. To set the stage, it is important to recognize that the next few years will be marked by significant trends in the packaged and custom
> Alignment, convergence, and consolidation among application logic, application integration, and application servers.
> Adoption of service-oriented architectures (SOAs) to design, architect, and implement business applications as a set of discrete business services.
> Adoption of Web Services as the preferred standardsbased integration technology across the architecture layers for SOA-based (and non-SOA) applications, and to drive the reuse of standards-based components.
> Increased use of programmable business process languages to describe business processes, workflows, and services — and as a macro driver for SOA implementations.
> Integrated and complete management of this emerging environment will depend on capabilities (discovery, security, availability, performance, change, etc.) at all layers within the technology stack and at all points in the operational process lifecycle.
These developments will enable a more direct modeling of the business environment and its processes, with the creation of technology objects that model the discrete business services that make up a company’s business processes. SOA design principles, enabled through Web Services, will
drive this new wave of enterprise software architecture, with business processes realized through loosely coupled, but semantically integrated composite applications.
