- 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.
