Lightweight microservice collaboration using HTTP

on YouTube ↗52m

" summary

Argues that microservice collaboration works well over HTTP, with commands as POST/PUT, queries as GET and a preferred pattern of asynchronous commands queries events implemented via an HTTP event feed (paged GETs with sequence numbers). Shows tiny demos using Nancy on ASP.NET Core, an in-process event store and a shopping-cart example that raises ProductAdded events. Recommends starting with HTTP polling for events, then migrating to queues like RabbitMQ only when scale or ops complexity demands it.
