Abstract

The Equipment Installment Plan (EIP) was a game changer in telecom industry and is an integral part of T-Mobile2019;s Un-carrier strategy. The EIP system is a home-grown system based on Java/J2EE and a combination of client-server and SOA architecture principles. The application runs on Bea Web Logic servers with Oracle DB with multiple batch jobs. As the system grew in size, operational challenges surfaced which includes multiple physical server security updates and maintenance cost. (DTT)201D; was the answer to address these challenges. The method employed PaaS Pivotal Container Services (PKS). Enterprise PKS uses the latest stable OSS distribution of Kubernetes2014;with no proprietary extensions. PKS is widely expansible to other applications in T-Mobile ecosystem as PKS can be deployed On-premises as a PaaS.
