Press Release Summary = Service-Oriented Architecture Makes IT a Strategic Partner
in Achieving Business Objectives by Decreasing Dependencies, Improving Communication
Across Disparate Systems and Enabling Reuse of Existing and Legacy Systems

Press Release Body = Torry Harris Business Solutions (THBS), a global niche
technology services and solutions provider for mission-critical distributed
enterprise computing and middleware, presents six steps to embarking on a
service-oriented architecture (SOA) implementation in a cost-effective offshore
model.

\"Successful enterprise IT managers today understand that SOA is not a luxury, it is
a necessary IT methodology that lends to a flexible infrastructure capable of
adapting to business needs,\" said Thiru Sivasubramanian, country manager USA, Torry
Harris Business Solutions. \"The next step is to select from the many implementation
options available, and this process need not keep decision-makers awake at night as
long as they begin with a clear roadmap. Our attempt is to help de-mystify the
methodology.\"

Torry Harris Business Solutions\' heritage is in middleware and distributed
enterprise computing, which has naturally evolved to become the basis of SOA
methodology. The company has worked and partnered with a myriad of SOA product
vendors, and provides advice on the use of open source software in SOA
implementation. By accessing the following elements, decision-makers can determine
the right path to SOA implementation.

1. Determine which business processes are most frequently changed

Identify the application or sets of applications that are impacted by the most
frequently required changes demanded by the business. This is the first step that
gives an idea of the project\'s scope, though in small segments. A parallel run will
be required during the transition that involves both legacy and different versions,
each incorporating more services, progressively exposed in each iteration.

2. Document use cases that will be impacted by changes to business applications

The documentation should include a study of client-based executables or interfaces,
invoked by each user community. The purpose of this study is to allow a fuller view
of the scope and establish a narrower set of important milestones.

3. Review server-based application code to identify and abstract business processes
from an application\'s functionality

The exercise of parsing business processes apart from an application\'s functionality
helps to form a reasonable estimate of the work and timelines involved, further
defining the scope of work.

4. Expose potential latency issues of re-use and content-heavy XML and the security
issues of opening these assets for access

When business systems operate conditionally, many of the tasks are buried deep
within the rules engines. The process of separating process from systems and making
each discrete will necessarily expose weaknesses. These considerations will
determine the classes and types of products to be used in the enterprise
architecture. Once this is done, the first sketch of the target architecture is made
visible.

5. Build and expose the separate functionality that is identified to be a part of
one or more business processes

At this time, it is important to get started. A registry and/or a repository that
describes the service is necessary, so that incoming messages can find them. The SOA
could initially be made available within the firewall, tested and then subsequently
made available through holes in the firewall that are opened specifically with
relevant security measures to allow access to nominated users.

6. Research and select the right offshore SOA partner

The selection of a SOA partner largely depends on whether a SOA product is purchased
or if a custom solution is desired. Selecting an entity that is knowledgeable in
both open source and proprietary solutions affords cost-sensitive and time-sensitive
options. Knowledge, skill and expertise is of little value without client-centric
support. The following questions should be asked: Is this merely a vendor or a true
business ally with domain-specific expertise? Is there visibility into the process
and is the support team accessible around the clock to meet your needs?
