Scaling Applications with Microservices and NServiceBus

##Microservices

Micoroservices is a software architecture style,in which complex applications are composed of small, autonomous processs communicating with each other using language-agnostic APIs.

Properites of Microservices

• Maintainable
• Versioning
• Each their own
• Hosting
• Failure isolation

• Observable

• UI
• Discovery
• Security
• Deployment

NServiceBus

• An implementation of a service bus.
• Written for .NET services.
• Non- .NET services can use other bus implementatations compatible with the same messaging system.

ESB

• Example:Biztalk
• Don’t confuse with our service bus
• Logic in bus

• Micorservices = dumb pipes

• Monoliths are great but become unmaintainable when they get more complex
• SOA with RPC and REST has some distinctive downsides
• Microservices solve these downsides but beware of the complexity
• The service bus facilitates the communication between services through a messaging backend
