Load Balancer with Consistent Hashing

1. Setup: 4 Origin Servers and 1 load balancer for routing requests to the origin servers.

2. Routing Logic: Use consistent hashing. Storing servers in the hashspace using their name. We store the keys on the rightmost node.
   Sample Implementation

3. Data Handling:

   • Simulate saving data to the appropriate origin server based on the hashed key.

4. HTML Form in Router: Created a web-based interface to:

   • Submit keys for routing and saving.
   • View server health.
   • Add or remove origin servers dynamically.

5. Health Monitoring: Display load on each origin server, at :8080/health.

6. Data Migration on Server Removal: TODO

Form to enter data

Health Server :8080/health

Adding New Server F, and sending data

Remove Server A, and migrate data
