Portfolio
Description:
This Internet Usage Manager is a middleware platform used by many telecom operators all over the world. Our product team was about 100 people including R&D, QA and support and deliver team. It was a distributed team with different branches in Russia, China, India, Spain, US and other countries.
I was responsible for supporting the management infrastructure of HEP IUM. It included a management server – a separate standalone process to monitor entire deployment and Operations Console – a WEB application to visualize state of deployment.
When I started to work on the central management server of the IUM platform, it had very small features and after several years, it already included services to support FCAPS (fault, configuration, accounting, performance and security) requirements described by ITU-T recommendations.
Currently the management server is a modern application that can be used in classic environments or in containers. It can be deployed in Kubernetes using provided Helm charts.
Technologies used:
Java, Rest Api, Spring, GWT, Prometheus, Grafana.
