RESTful Dockerized Expense management system Features Developed a simple expense management system that provides RESTful endpoints for CRUD operations using python flask. Achieved fault tolerance by implementing active replication of docker instances which increases availability. Implemented round robin load balancing for traffic distribution which eliminates overloading of a single replica instance. Implemented Redis routing table which routes requests to available replica instances and maintains it for upcoming requests. Achieved quick failure detection by implementing circuit breaker, preventing routing requests to failed replica instances. Implemented sharding using consistent hashing (configurable to use HRW/Rendezvous hashing) which improves scalability.
