  "account": "Request-Response is a widely used communication model in backend systems where a client sends a request, and the backend processes it before sending a response. This model is prevalent in various technologies such as HTTP, DNS, SSH, SQL, and APIs. The client specifies the request, which could be a continuous stream of data, and the backend must parse it to identify the start and end of the request. The server then processes the request, such as executing a GET request to fetch data from a database or sending a response back to the client. The request-response model is essential in understanding how data flows in network communication, as it helps engineers optimize the cost of parsing and processing requests. The model's versatility is evident in its application in various protocols, including REST, SOAP, and GraphQL. However, it does have limitations, such as its incompatibility with notification services, where the client does not need to make a request, and the backend already has the necessary information. To gain a deeper understanding of this model, building a custom HTTP web server from scratch and using tools like curl and trace can provide insights into the exact steps involved in request-response communication.",
  "summary": "Request-Response is the most famous communication design pattern for the backend, and it is literally everywhere if you think about it. You make a request; the backend processes the request and responds to you. I can keep on writing about it because there is so much going on in this request-response; you might need to kind of remove the layer and discuss it more. So, in a request-response model,…",
