openHPI consists of 20 Services, all written in Ruby. How can the overall Performance can be improved. Research and work in this field could be done on improving the existing services, improving the service to service communication or the evaluation of new technologies and frameworks.

Topic 3: Monitoring of SOA Web Application

How can the current monitoring Stack (New Relic) be replaced by a local service (maybe using ElasticSearch LogStash) or other technologies.

Topic 4: New Services and Apps

Prototype new services or stand alone tools to extend the openHPI feature set. This could also mean integrating existing or reusing existing apps. Example: Automated Slide detection, Collaboration tools, ...
