Monolith vs Microservice

CMU Maps server is a monolith application. You might wonder why we chose to not use a microservice architecture. Indeed, the Path Finding service needs to construct an in-memory graph, which is a very good use case for a microservice architecture. However, with our scope of CMU community, we would never need to scale to more than one server for the path finding service, so it is just simpler to have a monolith.
