When starting with an integration between applications, we can be overwhelmed by the number of protocols available. The criteria "What do I know already?" or "What is trendy?" will often guide us. But are there better criteria for selecting the best protocol for a use case?
In this talk, we will share our approach to categorizing and selecting protocols depending on the integration pattern needed, the business requirements, and suitability.
We will show methodologies like DDD and context maps that can help us find the best-suited protocol; we will include HTTP, gRPC, GraphQL, MQTT, AMQP, WebSocket, SSE, Kafka, NATS, etc.
