SOA Reference Architecture for large Electric
Utilities Company |
Leveraging SOA best practices, Patni helped a leading Electric Utilities company create a
blueprint for adopting an organization-wide SOA framework.
The Client
The client is one of the largest investor-owned electric utilities company, providing power to over 11 million consumers, and 5,000 large businesses.
The Challenge
Operating in a marketplace that demanded agility, the client's IT landscape
consisting of multiple technologies and architectures from mainframes to
client server, was hampering the client's competitive ability, as most
technology architectures were inflexible and expensive to maintain. To
standardize tools, technologies and technology architecture used in the
organization by various units, the client had formed a Strategic Integration
(SI) group.
This group had created a conceptual and logical architecture which was
meant to guide every IT team for adopting best practices for creating an open
standards based architecture, and streamline the organization's diverse
technology initiatives for adoption of SOA across the organization.
However, with non-availability of well defined implementation specific
guidelines, libraries of reusable components and ready to use frameworks,
the different IT teams scattered across the organization faced a huge
challenge in mapping the architectural principles as defined by the SI group.
This created a huge disconnect between the SI group and members of the IT
team of different units, as most internal IT projects did not involve
participation of enterprise architects from the SI group. Lacking internal
expertise to create a roadmap for adoption of SOA across the organization,
the client decided to partner with Patni.
The Solution
Leveraging experiences and knowledge gained from internal SOA initiatives, Patni helped the
client create a blueprint for adoption of SOA. The blue print laid down the major tasks like
creation of SOA reference Architecture, creation of Technical Solution Architecture, Tools
evaluation, creation of Architectural Prototype and establishing guidelines and standards for
adoption of services As a first step in this roadmap, Patni created a reference architecture
that was developed to such a level of detail that project architects could use it effectively for
creating architectures that adhered to architecture principles and SDLC processes of the
client. The objective was to create a reference architecture that promoted reuse, improved
interoperability and reduced integration efforts
Patni adopted a holistic approach for creating a SOA roadmap. This consisted of creating a host
of reference architectures which addressed every aspect of implementing a SOA roadmap. The
following reference architectures were created by Patni:
 |
Business Process Architecture: Reference architecture for modeling business processes
and generating business services from the business processes |
|
Service and Composite Application Architecture: Reference architecture for designing
individual service components participating in SOA and for designing applications composed
from services |
|
Information Architecture: Reference architecture for creating information model for a
service Technology Architecture: Reference architecture for selection and organization of
technology infrastructure required to support services during their entire lifecycle of
operation |
|
Integration Architecture: Reference guide for creating architecture for integration of
applications via services |
|
Security Architecture: Reference architecture for addressing security requirements for
services participating in SOA. |
Patni also conceptualized a governance model that detailed the approach, organization
structure and processes for design and run time. Subsequently, Patni created review and audit
processes for compliance checking, policy management, reuse and technology change
management. To ease implementation, each of the reference architectures articulated the
method for architecture development, aided by guidelines, templates and checklists to help
architects create an architecture that mapped to SOA guidelines. Patni also provided design
patterns, reference technology stacks, along with guidelines and criteria for selecting and
using tools.
Impressed with Patni's expertise in creating a SOA roadmap, the client invited Patni to continue
to guide the former in realizing its SOA vision. Accordingly, Patni has formed a team comprising
of architects and designers based at onsite and offshore locations. This team today serves as a
virtual extension of the client's SI group, and assists the client in core activities such as review
of architecture / design for application development projects, research on new areas as
specified by the SI group, developing proof of concept for new technologies or tools, and
creation of standards and guidelines.
The Benefits
Given the diverse nature of technologies being used, it was very challenging for the
customer to hire and maintain a large team with different skills. Patni's team acts as a
virtual extension to the client's architecture team and has given the latter the ability to
access and leverage Patni's large pool of experienced architects for specific tasks.
By deploying an onsite-offshore based team, Patni has helped the Enterprise
Architecture Group within the customer organization garner multiple tangible and
intangible benefits. Some key benefits include:
|
Ability to ramp up or scale down the team according to peaks and troughs in business
demands |
|
Ability to leverage streamlined processes and standardized technology architectures
from Patni |
|
Significant cost reduction due to offshorization in the high end consulting area which
is traditionally not very prevalent. |
