Building Microservices in .NET with NServiceBus

This session introduces the concept of Microservices and explains some of the characteristics of how a system of loosely coupled services should communicate. We then look at how to implement a microservice architecture in .NET with the NServiceBus framework.

3. Agenda
5. User interface Business logic Storage External integration
7. Services as a network of independent parts
9. that’s still Coupling!
10. (reliable) Messaging
11. Loose coupling Share contract and schema, not class Temporal decoupling through queued messaging
12. Event driven architecture Services keep their own state Events are used to notify changes Each service will have its own database Services use events to replicate data
13. Sales Billing Shipping SubmitOrder OrderAccepted OrderBilled OrderShipped
14. Costs Latency in data changes Challenge to reconcile in case of disaster No central control of business logic Event driven architecture

18. NServiceBus a service bus is an architectural style for integration
20. Where is the bus? Like Ethernet, it’s everywhere!

22. What is NServiceBus? A .NET framework to help implement SOA microservices with the Service Bus architectural style
23. Abstracts away transport, threading, queues, transactions What is NServiceBus?
24. Focuses on implementing business logic What is NServiceBus?
25. Highly pluggable What is NServiceBus?
