In this talk, I will demo how we can build deploy and monitor a couple of (micro) services using the .NET platform. On the Java platform, we have a LOT of options to implement micro services, this is not the case on the .Net platform, let's look how we can do this using .Net tools like NServiceBus and Octopus Deploy

1. Building (micro)
Services On .Net

2. Why Microservices?
Break down the monolith

3. Fallacies of
Distributed Computing
1. The network is reliable. (Bill Joy and Tom Lyon)
2. Latency is zero. (Bill Joy and Tom Lyon)
3. Bandwidth is infinite. (Bill Joy and Tom Lyon)
4. The network is secure. (Bill Joy and Tom Lyon)
5. Topology doesn’t change. (Peter Deutsch)
6. There is one administrator. (Peter Deutsch)
7. Transport cost is zero. (Peter Deutsch)
8. The network is homogeneous. (James Gosling)

5. Why SOA /
Microservices?
“Address coupling in our software
design by building loosely coupled and
highly encapsulated components”
Udi Dahan

6. Coupling
• Synchronous communication
(Request Response)
• Resource sharing (data, code)
• Coupling Aspects (Temporal, Spatial,
Platform )

7. Decomposition
• Breaking down functionality into small
autonomous components (vertical
slicing)
• CQS/CQRS
• Inter components communication?
• Messaging

8. Tools in .Net
• Akka .net/ Orleans (actor frameworks)
• MassTransit
• Re-bus
• NServiceBus (particular.net)
• Build your own

9. Functionality
• Submit Order
• Wait for Buyer’s Remorse
• Ability to Cancel Order (within buyer’s remorse)
• Process Order (charge credit card)
• Provision Download
• Make Customer preferred
• Send Welcome Email
• Send Limited Time Offer

10. On Premise Sample
Demo

11. Components
Submit Order Notify: Order Placed
Buyer’s Remorse
Optional: Cancel Order
Process Order Provision Download
Make Customer
preferred
Send Limited Time
Offer
Send Welcome
Email

12. Sample code
