In any case, when choosing architecture, it is useful to study someone else's experience of moving from a monolith to a set of services.
 
 
We asked to share our development and delivery case for Alexey Bayitov, a leading engineer of the 2GIS. Let's talk about the architectural solutions, deploy and scalability. We will ask about trend and simple ...

RabbitMQ versus Kafka: application of Kafka in event-oriented applications

In the previous article we looked at the templates and topologies used in RabbitMQ. In this part, we turn to Kafka and compare it with RabbitMQ to get some idea of ​​their differences. It should be borne in mind that the architecture of event-oriented applications will be compared rather than data processing pipelines, although the line between these two concepts in this case will be rather blurred. In general, this is more a spectrum than a clear division. Simply, our comparison will be focused on a part of this spectrum associated with event-driven applications.
