IBM's SOA Foundation lifecycle
The IBM SOA Foundation is an
integrated open standards-based set of IBM software, best practices, and
patterns. The key elements of the IBM SOA Foundation are the SOA life
cycle (model, assemble, deploy, manage), reference architecture, and SOA
scenarios. IBM's SOA Foundation lifecycle consists of the following
iterative phases and some of the key activities performed:
When developing SOA-based
solutions, you can adopt the SOA lifecycle by mapping what activities
are performed in which phase and also identify which tools and products
can be used to fulfill activities in that phase. The lifecycle, as shown
in the following figure, outlines the key IBM products that could be
used to fulfill some of the key activities in each phase to deliver the
solution. Products marked in bold are the ones we will be covering in this book.
IBM's BPM enabled by SOA method
As mentioned earlier, SOA
is not a technology but glue that cements the holistic relationship
between IT and business. BPM again is a practice of focusing on the
improvement of operations efficiencies within an organization by
modeling, automating, and monitoring their core business processes. Both
BPM and SOA are an art into themselves. Some of the key concerns,
questions, and topics that arise when venturing into the adoption of BPM
and SOA may include:
How to identify
process metrics and KPIs which are not only aligned with my core
business performance objectives, but also help me constantly improve?
How can I set up and implement a process governance and management framework?
to identify an implementation of a continuous and iterative BPM process
optimization cycle that improves business and process agility?
How to realize the value of applying BPM to deliver business processes?
are the set of phases, associated activities, and deliverables that I
should adopt for the BPM solution development and management?
So when I'm building
solutions with a BPM enabled by SOA approach, what are the lifecycle
phases and what do I typically do in each of the lifecycle phases? Also,
how and where do WPS, WESB, and potentially other products from IBM
apply to each of the lifecycle phases? Let's look at IBM's BPM enabled
by SOA methodology.
IBM's BPM enabled by
SOA methodology provides a structured set of activities that you can
manipulate and use in the build out of SOA and BPM based solutions. By
using the method correctly, you can be assured that the solution
including the business processes and Business Services will be aligned
with business goals and that it creates a framework for continuous
improvement. As shown in the following figure, the BPM enabled by the
SOA method has five primary phases, which are as follows:
