Forget about HTTP

Explore various approaches to data exchange between microservices in this comprehensive conference talk. Learn about the limitations of simple HTTP calls and the benefits of adopting messaging or RPC systems for more robust and scalable architectures. Examine different strategies for inter-service communication, including API calls, service discovery, gRPC, and messaging concepts. Discover the advantages of messaging systems, such as increased agility, scalability, throughput, and reliability. Delve into topics like temporal coupling, reactive systems, message brokers, and enterprise integration patterns. Gain insights into the trade-offs between different communication methods and understand why HTTP may not always be the best option for microservices architecture.
