Gaining insight into the health of SOA infrastructures
by R. N. Chang,
and N. C. Wadia
As service-oriented architecture (SOA) is evolving from theory to
practical applications, the demand for deriving actual benefits from
the infrastructure flexibility it enables is increasing rapidly.
However, an SOA implementation often poses capacity and
performance management challenges for the IT (information
technology) delivery organization, particularly when dispersed
business applications run on heterogeneous systems and various
internal and external infrastructure components are used to
complete business service transactions. To help organizations that
are considering or have engaged in SOA infrastructure
implementations, IBM has developed innovative and non-intrusive
capabilities to help determine the optimal infrastructure
architecture for a particular SOA project and identify areas of
performance improvement for running an SOA infrastructure.
These capabilities are provisioned as infrastructure Healthcheck
services for SOA, reflecting a trusted IT service management
approach that focuses on prevention or a solution to an IT
infrastructure capacity and performance management problem.
This paper presents the development rationale for the key service
delivery components, including the analysis process, the use of
global (i.e., worldwide) delivery capabilities, and the proprietary
assets and patented technologies used in performing the services.
Insight into how these services can lead to significant positive
results is exemplified via several commercial client engagements.
