This 2-day course covers the fundamentals of Event-Driven Architectures, focusing on scalable, fault-tolerant systems. You'll learn about key tools like RabbitMQ and Kafka, with practical exercises to design and assess architectural solutions.
Introduction
Event-driven architectures can help build autonomous, scalable and fault-tolerant systems. However, like any architecture, it has distinctive features that can cause far-reaching complications if not understood well. Join this training to gain a deep understanding of the fundamental concepts as well as patterns and pitfalls of Event-Driven Architectures. Developers of any programming language can attend, because the focus will stay on a pragmatic understanding of architectures and tools rather than specific implementations. The acquired skills will allow participants to correctly design architectural solutions and perform thorough tradeoff analysis and risk assessments. You’ll also learn how tools like RabbitMQ, Kafka, and Cloud-Native messaging systems differ and how selecting them can impact your architecture.
During the training, you can expect explanations in simple terms, accompanied by suggestive visuals and real-world analogies that will help you easily understand and remember complex topics. The teaching style will be highly interactive, with plenty of debates to engage in. You'll have endless opportunities to discuss issues that are of interest to you, and there will be many simple exercises to apply the concepts you learn.
