![]() To support the need for these functionalities, other protocols have been built specifically for messaging systems. Inefficient Pub/Sub model: It does not have a direct way of addressing pub/sub pattern to support multiple consumers that can retrieve messages from a single producer.Low Latency: HTTP does not address low overhead messaging in scenarios in cases like IoT environments where demands for low latency and async communication are crucial.Reliability: With HTTP, it is difficult to acknowledge every instance of message delivery when issues such as network failure or system crash arise.Its stateless nature makes it inefficient to handle persistent connections with high throughput and concurrent connections. Scale and efficiency: With HTTP, we have to create a new connection for every request to access the underlying resources.For this reason, HTTP is widely used for communication that mainly involves fetching a resource on a service but fails to address concerns such as: The HTTP standard is a stateless protocol built around the request-response communication model where a client sends a request and the server returns a response. Most of the communication over the internet happens thanks to the HTTP protocol. An application passes the messages to a messaging system with the assurance that the information will arrive at its destination. Just like you would typically hand over a package to a postal service and trust that the carrier will deliver, so is with messaging. Messaging involves the exchange of information between different systems via messages in a loosely coupled manner.
