Microservices in .NET Core: Introduction
Over the past few years microservices have proven to be a very useful architectural approach for a great many systems. Microservice systems can enable continuous delivery and great business agility, be highly robust, scalable and maintainable. On the other hand microservices come with their own complexities and also requires a certain level of maturity technically and organizationally. In this workshop you will get an introduction to microservices, you will learn how to succeed with them and what the pre-requisites to working with microservices are. On top of that, you will get an introduction to a lightweight .NET based tech stack well suited for building microservices - consisting of .NET Core, Nancy and few other things.
This course is built in part on my Microservices in .NET Core book and of course on real world experience building microservices.

Duration: 3 days


Event Sourcing and CQRS with .NET Core
Event sourcing is an approach to data persistence that is safe and flexible at the same time. It safely stores data in log over all changes ever made. Nothing is lost. At the same time, event sourcing give us tremendous flexibilty to changes the business rules that govern how the data is used. These are some of the reasons that event sourcing has become increasingly popular over the past years.

Command-query responsibility segregation or CQRS for short is an architectural style that allows for a high degree of separation of concerns that makes a good fit for complex collaborative domains. Furhtermore CQRS fits well with event sourcing, which I will show in the course where we start from event sourcing and evolve the software to a CQRS design.

In this workshop participants will get a hands-on introduction to event sourcing and CQRS. We will expand on that introduction to show how event sourcing tends to introduce a need for "readmodels". Along the way there might be an anecdote or two from using event sourcing and CQRS in the real world and under heavy load.

Duration: 2 days
