Aircel : Aircel Transformation Initiative

Aircel initiated a Transformation initiative along with Wipro to transform

itself from a regional operator to the one having a pan-India presence in mobile

operation. So, Aircel decided to build a new end to end IT stack and expand its

newer businesses on the OSS/BSS and other periphery systems and gradually

migrate the legacy business on it. Aircel architecture and services have been

framed using the SOA concepts and framework with an Enterprise Service Bus layer

coordinating and orchestrating all the interactions between any two systems in

the OSS-BSS ecosystem. All systems (like CRM, order management, inventory,

billing, provisioning, prepaid-IN, SDP) expose their services via the Enterprise

Service Bus. These services are registered in an enterprise wide registry of

business services, promoting easy service discovery. The process of registration

of new services requires documenting the design, data model updates, and

contract documents with details of the message structure and interface. All the

service artifacts related to design, contract documents, data models, WSDL

files, XSD documents are managed in an enterprise repository which is linked

with the enterprise registry to manage versioning of services. Aircel now has a

library of business services, provided by various systems in IT ecosystem, which

are used by all consumers of the services, promoting re-use of the services and

reducing the headache of maintaining multiple versions of services for

accomplishing the same task.
