Accelerating SOA performance via transport optimization
[by Srinivas Padmanabhuni, Ph.D]

XML has emerged as the lingua franca of service-oriented
infrastructures, forming the basis for all the SOA standards in
vogue. However, the performance gaps in SOA deployments due to
verbosity and voluminousness of XML, combined with chatty transport
protocols is a cause of concern. Different approaches have been
suggested and adopted to deal with this performance bottleneck, key
among which are:

-XML compression including compact intermediate representations
-Caching
-Offloading via accelerators
-Transport-level optimization
-Optimized XML processing like specialized parsers for specific
schemas, etc.

While the first three approaches listed above are already mainstream
in commercial deployments in different products and custom
implementations, the latter two strategies of transport level
optimization and optimized XML processing are still to get the
attention of the SOA product community. We believe the experimental
results from these two approaches in the field are encouraging and
these approaches will become mainstream for tackling the SOA
performance challenge.

The notion of optimizing transport level protocols for better SOA
performance is important, given that SOAP, the fundamental SOA
protocol, rides on top of underlying transport protocols and is
transport agnostic. In these approaches, for end-to-end optimization
special attention is paid to optimize the transport protocol (e.g.
HTTP) to handle Web service payloads. To date, HTTP has emerged as
the prominent protocol to carry Web service payloads. In the recent
past, special attention has been paid to optimizing HTTP and HTTPS
protocols to get optimal performance for Web services.

The Economics of SOA
As service-oriented architectures (SOAs) gain mainstream acceptance,
IT professionals that are looking to implement them into their
infrastructure will ask the question: Will a SOA actually save me
money? This case study describes how a telecom company calculated and
compared costs of a traditional EAI approach to an Enterprise Service
Bus solution and which solution yielded the most efficient cost
savings.

* SOA and EDA: Using events to bridge decoupled service boundaries
[by Jack van Hoof]
The distinction between service-oriented architecture (SOA) and
event-driven architecture (EDA) can be traced to message patterns.
Understanding the implications of common exchange patterns, such as
request-and-reply and publish-and-subscribe, helps determine both
fundamental differences and commonality in these two complementary
architectural models.
