Hi,
for this years GSoC, I think it would be interesting to have students evaluate some ideas.
For Push Server:
* Apache HBase database model for UPS + migration of data from SQL (MySQL/Postgres) to HBase
* Apache Kafka for centralized messaging in UPS
* Apache Spark for realtime processing of our push metrics
Some of the above ideas are already capture in this larger/raw JIRA:
For Jenkins-Digger:
* Windows containerized Docker builds
