What is Axon Framework and Axon Server for?

Question

Web development

Now I'm studying how https://axoniq.io/
works. As I understand it, this is actually a CQRS framework that allows you to send commands and requests, and route through the entire microservice architecture of the project. Am I correct in my understanding that this is so?
And the second point, for which it is usually required (used). And if not Axon, then what is it usually replaced with? Those. I want to understand the user case (problem) when to use axon.

Answer 1

Judging by the description, this is a regular enterprise service bus.
To communicate microservices.
The most popular options are RabbitMQ or Apache Kafka.
