In today’s world, microservices are essential to building scalable and modular software systems. However, communication between microservices can be complex - that’s where LavinMQ comes in. LavinMQ is a new lightweight message broker that’s anchored on ease of use and performance. By leveraging LavinMQ, you can easily build faster, more resilient, and more efficient Python microservices-based applications. In this presentation, to begin, we will explore the basics - covering the fundamentals of LavinMQ, its strengths, and how to install and configure it. Next, we will walk you through how Python/FastAPI can be used to spin up a rudimentary microservice architecture using LavinMQ as the medium of communication between the services. Lastly, we will briefly talk about how the rudimentary microservices can be improved to meet more real-world requirements - while touching on when to and when not to adopt a message broker/LavinMQ in your architecture.
