(Is it time to learn gRPC?) I love REST, I think in REST. Truly. It’s been the reliable workhorse of web development for two decades. Simple URLs, JSON payloads you can read in Notepad, and an army of Stack Overflow answers at your fingertips. REST won the web and for good reason. But inside a modern data centre? It’s starting to feel like we’re turning up to a F1 race in a Volvo estate and no-one has ever got a winch driving a Volvo.
