Poster Service
The Poster Service provides an API that serves as an abstraction to the OMDB API. It is based on micro, a library specifically developed for asynchronous HTTP microservices. It is highly performant, simple to deploy, and very lightweight.
Micro — Asynchronous HTTP microservices
The Poster Service is stateless, meaning that it does not store any particular state and can, therefore, be scaled easily should it be necessary. The service only gets an IMDb-ID as a param and queries the OMDB API, after which it returns a high-fidelity poster path. We do not need any data from the OMDB API besides the poster path.
