I Replaced Kafka, Redis, and RabbitMQ with One Tool – A Deep Dive into NATS

The guide is very detailed, so I've saved some for later. I've been using NATS I think since around 2018-2019 (can't recall). I've only used its pub:sub feature as it was MUCH lighter than Kafka.

It's interesting that the platform has grown so much. I paused reading at the inbox feature, so there's more to dig in to. I enjoyed reading the topic guide, and I think it was pretty intuitive when I started using it.

Outside of work projects, I maintain a public transit info site, where I either estimate or process telemetry feeds to generate trip updates, alerts, vehicle positions. NATS pub:sub works so well for me (along with tidwall:tile38 for geofencing). The site isn't that large, but a large volume of messages pass through NATS every few seconds. It's really been a great reliable small piece of technology.

It's very interesting topic, too bad it's an ai;dr for me
