Challenges
- Integration of 20+ systems to create a Services Oriented Architecture (SOA) layer and developing applications leveraging it. Current challenges faced were:
- Not systematic communications
- Billing, provisioning, in-house, third party applications
- Duplication of efforts
- Complicated & time consuming
- Operational instability & security risk
- Unfamiliarity within developer community of various technologies
Solutions
- Created a WebLogic/Aqualogic-based SOA layer providing refined coarse-grained services:
- Multiple back-end integration including fine-grained, Java, .Net, MQ, file based, DB based
- 3 versions of the services for consumer
- SOAP/ REST interface
- Built-in security
- Throttling for consumers integrations with multiple systems of record and data sources, including multiple legacy billing systems
- A customer care application integrating 20+ back end created without the hassle of dealing with the complexity of various systems
Tools & Technologies
Java, Microsoft .NET
Key benefits
- The new customer care application was easy-to-use and maintain and resulted in savings in millions of dollars by improving efficiencies in the process for triage and Tech dispatch
- A web-based interface was created on top for the customer care application with around 30,000 users for the UI and 100 millions transactions in the SOA layer
- $35 million / yr. reducing avoidable truck roll and AHT
- The SOA enabled easy development of applications at lesser costs
- A scalable, high-availability, high-performance, secure architecture
