In this tutorial, we will look at distributed systems, such as microservices, and how we integrate them. We will understand why we would prefer to messaging, the fundamentals and key concepts of messaging and how to build an event driven architecture. If you have ever been put off moving from HTTP or RPC-based solutions to messaging because of the need to learn how to implement messaging-based solutions, this workshop will get you started. if you have been using messaging but want to gain a firmer understanding of how to build event driven architectures, this workshop will help you understand how to succeed with reactive approaches.



The material is presented in four parts: integrating distributed systems, an introduction to messaging (hands-on exercises), advanced messaging, and event driven architectures.

Hands-on exercises are offered in C#, JavaScript, Python and Go.



Messaging Architectures and Simple Patterns

Insights from Paper Offices and Flow-Based Programming

Commands or Event? Orchestration and Choreography.


We will use Rabbit MQ for examples. You need not have the latter installed on your machine, but you should have Docker installed on your machine, as exercises will use Docker Compose.

This is a Bring Your Own Device (BYOD) course. At BYOD courses delegates are required to bring their own laptop with the necessary software installed.

The exercises are self-paced and you will find it helpful to have headphones to listen to the material that accompanies each exercise (though scripts are provided for those who cannot use headphones).

Increasingly developers are relying on distributed architectures to solve the problems of scaling their applications and their development teams. But that means they now have to consider the problem of getting the parts of their systems to talk to each other.

We believe in a world of work where people can find their true self and achieve their full potential. This not only makes individuals more satisfied and happier, it also makes companies more successful. 
 
Based on this conviction, New Work SE aligns its brands, products and services around its vision – For a better working life. We’re already seeing a paradigm shift in terms of what we call ‘work’. Demographic change is exacerbating the shortage of skilled workers, in turn shifting power away from employers and over to employees.

Digitalisation is not only revolutionising entire industries, it also enables people to work wherever and whenever they want or need to. And younger generations, in particular, are eschewing long-standing values in favour of more modern ones with a clearer focus on a positive work-life balance.
 
All of these aspects are already driving radical change on the labour market. All of the activities undertaken by each New Work Group brand aim to help shape the future of work and gear it more towards people, while assisting companies in the pursuit of success by enabling employees to do what they really, really want to do.
