Process-driven SOAs are using processes to orchestrate services.
Designing a non-trivial process-driven SOA involves many difficult design and
architectural decisions. Examples are: Different kinds of processes exist: longrunning,
business-oriented and short-running, technical processes. How to best
integrate them and how to map them to execution platforms? A SOA has many
different stakeholders, such as business analysts, management, software
designers, architects, and developers, as well as many different types of models
these stakeholders need to work with. How to present each of them with the
best view on the models they need for their work? A realistic process-driven
SOA contains many systems that need to be integrated, such as various process
engines, services, and backend systems, running on heterogeneous technologies
and platforms. How to perform integration in a way that is maintainable and
scalable? This article introduces a pattern language that deals with process
modeling, execution, and integration. Its main goal is to help solution architects,
as well as process and service designers, to master the challenges in designing a
stable and evolvable process-driven SOA.
