Ask HN: What is the state of ESB?
Traditionally ESB is the centerpiece of an architecture. How relevant is it these days. Do people still start grand projects to unite all systems and what are the tools and OS projects taking its place? Kafka is the 'cool' thing to build stuff with.I assume people can get a lot of mileage with pub-sub and use grpc where they can. What mordern OS tools are filling a similar gap?
