CV is one of the best minds on messaging-oriented communication and distribution I know. Highly recommended reading.

"Why would I care?"

Generally, if you are building software that requires more than one computer to do its job, you should know about asynchronous messaging concepts.

"Asynchronous" means here: Your application sends a message or event and then carries on doing something else. It does not sit around waiting for an outcome.

For many developers, that is the first giant mental hurdle, since we've all been raised on "imperative" programming models. You make a function call and cause some work to happen and only once that work has been reported as done (or failed) your own code continues with its work.

Yet, we all use asynchronous messaging every day in the physical world. If we want to send a gift to someone in a different city, we will go to the post office and entrust the postal service with the package. The postal service takes care of getting it to the destination and also tracks and reports whether the package has been delivered successfully. Once the package has been delivered, your friend might then call you and excitedly thank you for the gift you sent. If you ask for it you will get feedback, but maybe on a different channel and after however long the handling and delivery took and usually with a clear reference to the package you sent.

That is what asynchronous messaging infrastructure does, but for your apps.

Definitions: Messaging or eventing infrastructure

"Message broker", "queue", "service bus", "event router", "event stream engine", "event aggregator", are all names for asynchronous messaging and eventing infrastructure elements and the list is by no means exhaustive. I will give you a brief definitions for all the words in those names for orientation.

Introductions and Patterns

Open Standards

Books

An incomplete list of books about product-/project-neutral messaging and
eventing principles and patterns. I am an impatient book reader and prefer going
straight to authoritative documents, therefore I am happy to take PRs for this
section from readers who've been helped by particular books.

Products & Cloud Services

Apache

The Apache Software Foundation hosts several popular open source projects that
produce message and event broker infrastructures.

CNCF

The Cloud Native Computing Foundation also hosts a few messaging and eventing
centric projects.

Eclipse

The Eclipse Foundation has a strong IoT focus and hosts various MQTT-related
projects. It is also hosting the Jakarta Messaging project that carries forward
the popular JMS standard.
