SOA Blueprint: A Toolbox for Architects – article at OTN and Service Technology Magazine
By JuergenKress on Apr 24, 2013
this article introduces the foundations that need to be established in order to implement functional SOA processes. Rather than presenting specific tools, we will define a broadly applicable SOA blueprint whose individual modules can be topped up with commercial products or increasingly available open source offerings.
A Company Blueprint
Upon examination of Figure 1, the vision of adaptive enterprise computing is illustrated as a meta-blueprint for the overall company with three differentiated levels:
- Infrastructure Level - This level is formed by databases, storage systems, application servers, and all other IT resources that are required to run IT systems.
- Application System Level - This level houses entire applications, both individual applications and standard software, as well as services relating to SOA, workflow and BPM systems.
- Process Management Level - Functional requirements are manifested in the process design and then implemented at the lower levels.
An advanced service-oriented architecture is the most effective option for implementing the functional requirements at the application-system level. The more superior the mapping of existing business services to the functional steps in process models is, the more the business-IT gap shrinks.
Various back-coupling loops represent the actual added
value of this meta-blueprint, meaning consistent usage of services and
technical processes enables the measuring of KPIs. This in turn
facilitates process control and ultimately the optimization of
processes. The more progress a company makes in implementing their SOA,
the greater and faster are the effects to be achieved for adaptive
enterprise computing. ... read the full article here
