Project Description

The Fixed Access Rollout Orchestration (FARO) system is a cloud native software platform whose main task is the automation of business processes. FARO is based on a microservice architecture written in C# .NET. It provides process control (so called MissionScheduler) and connects to 3rd party systems in the environment of the processes (so called connectors). In the future FARO will enable our new process platform Camunda with connectors. The team in addition to developing connectors for FARO will also be responsible to develop templates and APIs for Camunda.
