Requirements

Functional Requirements:

• Create a short URL for a given long URL.
• Return the long URL associated with a given short URL.

Non-Functional Requirements:

List the key non-functional requirements (eg low latency, scalability, reliability, etc.)...

API Design

Define the APIs expected from the system. This is your chance to analyze and define the read and write paths so that you can come up with the high-level design...

POST /v1/shortUrl

{

"longUrl":"https://codemia.io/system-design/designing-a-simple-url-shortening-service-a-tinyURL-approach"

}

GET /v1/getUrl

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.

Client first call load balancer and then from load balancer it first call redis database. if data present in redis database then return long url.

else go to the DB and return long url.

Detailed Component Design

Deep dive into 2-3 key components. Explain how they work, how they scale, discuss tradeoffs, capacity, and any relevant algorithms or data structures.
