I will talk about approaches of queue usage and key parameters worth looking at like scalability, durability, guaranteed delivery, availability vs consistency and throughput.

Most microservice architectures and distributed applications require some kind of messaging service. It is called message broker or message queue as an inevitable element of system design.

There are quite a few of them, with their own pros and cons. The wrong choice of this component could lead to problems with scalability or fault tolerance in your application.

In my talk I point out key moments in choosing a queue, as well as guide you through the comparison of RabbitMQ, Kafka, NATS and other candidates.
