System Design

In this assignment we created three servers which are listed as follows:

Server_in_memory - This server only uses in memory queue and is not persistant

Server_persistent - This server only uses database to serve user requests and hence is slower compared to in-memory server

Server_backup - This server uses both in memory queue and database to keep backup. It has improved latency over server_persistent

This design is shown in below diagram:

The schema of used database is shown below:
