Message Passing Middleware Resurection
In the olden days of the 1980s, "middleware," including messaging middleware was all the rage. BEA systems, Vitria Systems, Tibco, and a slew of others competed to sell horizontally-scaled messaging middleware to the largest enterprises. eBay's "Business Events Service" (BES) bus is a 1980's based publish/subscribe system based on Oracle and Vitria middleware. There are still many advantages of message-passing middleware system patterns over our current RESTful stateless HTTPS fashion. A few modern, containerized versions of those venerable systems are coming back into vogue. One such system is NATS.io. Malta-based consultant R.I. Pienaar has written a great 5-part series on how NATS.io is applied in his "choria" puppet orchestration system. What is old is new again!
