Here is the component of the system design framework, it provides a systematic thinking approach to system design.

To simplify the design process, we should design each layer in the following order:

Client -> Load Balancer -> Web Server (API) -> Storage.

• For Read API, we need Cache.

• For Write API, we need SQL Master/Slave.

• For API Async, such as worker -> We need queue.

• For API need service communication, we use grpc DNS, queue, distributed cache.
