NATS and Synadia's other tech is easy to understand. You're not the target demographic for the Synadia site. They're targeting enterprise. You can find the NATS site here [1]. NATS is so flexible it's admittedly easy to get lost in what exactly it is or what it's good for. The easy explanation is it's a message broker that can let programs send and receive messages to each other. Unlike a message queue, it has no persistence. Clients can that express "interest" in a topic receive messages to that topic, but messages disappear if nobody listens to them. It's kind of like UDP without addresses. It's clustered and supports complicated topologies where clusters route messages to each other, and has a powerful ACL system for exposing clusters to unprivileged actors that shouldn't be given full access (which means you can easily make it multi-tenant). The closest comparable technology might be MQTT, and indeed NATS offers an MQTT mode. NATS also has a bunch of higher-level stuff built on top of it: A Kafka-like "stream" feature called Jetstream, RPC, a key/value store, an object (blob) store, and so on. The NATS message bus is the core primitive that these features use. [1] https://nats.io/ https://nats.io/
