MoviesRatingApp

it is an application where users can rate movies and give feedback. It has been created using microservices architecture where services communicate between each other to get the desired data.

Features

Service Registry to check all the services status
Config server is used to get common configurations from github
API Gateway created for calling any services endpoint from only one port number
Secured API Services with security using Okta
Rate Limiter implemented to reduce pressure on server and fallback method created for dummy data in that case for services
Actuator health status
Using sevice names instead of port number to call other services

API Reference

POST: Create a new Movie or User or Rating
GET: get according details

Optimizations

Implementation of security at Userservice,MovieService and Ratingservice are in progress...
