Opis

Swiss Federal Railways operates more than 750 applications on a container platform called OpenShift. As this container platform contains business critical applications - like the main mobile website or the backend of the main mobile app - the platform has an availability goal of 99.99%. The experience of operating the productive platform for two years showed that the main risk for unplanned downtime, is maintenance at the platform itself. Ahead of this master thesis, Swiss Federal Railways had an idea of how to address this problem. To verify this solution idea is the goal of this master thesis. The solution idea claims that in the existing OpenShift setup, only one piece is missing in order to achieve risk free cluster maintenance. The missing component is a smarter load balancer. In the following thesis, the solution idea will be tested using a prototype of that smarter load balancer.
