The microservices approach

Scales by cloning the app on multiple servers/VMs/Containers Monolithic application approach Microservices application approach A microservice application separates functionality into separate smaller services. Scales out by deploying each service independently creating instances of these services across servers/VMs/containers A monolith app contains domain specific functionality and is normally divided by functional layers such as web, business and data App 1 App 2 App 1

Single monolithic database Tiers of specific technologies State in Monolithic approach State in Microservices approach Graph of interconnected microservices State typically scoped to the microservice Variety of technologies used stateless services stateless services with separate stores stateful services stateless presentation services

Demo: Building reliable actor applications

Build stateless services using existing technologies such as ASP.NET, node.js, EXEs etc Manage concurrency and granularity of state changes with transactions in stateful services. Communicate with services using the technology of your choice (e.g Web API, WCF, [web]sockets, etc).

Reliable collections make it easy to build stateful services. An evolution of.NET collections for the cloud.

Data is replicated and durably stored on multiple replicas. Atomically update one or more collections using transactions. Supports LINQ. Reliable Collections IReliableQueue IReliableDictionary
