High-Level Design

Describe the overall system architecture. Identify the main components needed to solve the problem end-to-end. Use the diagramming tool to create a block diagram.

When the client sends a request for a first time fetching of shortened url, it is sent to cdn for faster access, if its a request for new shortened url, its sent to load balancer

if cdn has the original url, it returns or else its sent to load balancer

now the load balancer uses a round robin to select a server for the task(new shortened url), but if its just fetching, it goes on directly to db server to fetch original url and return it to client

server 1 and server 2 can fetch data and return but load balancer does the task for now, but if its for creating a new url, they can handle

db server is used to shard data around a n databases, so that fetching can be faster

server 1 and server 2 can be used to add analytics and other kind of dashboard services (there can be n servers)
