Microsoft Azure Service Fabric Traditional vs Microservices approach Microsoft Build 2016 9/18/2018 3:33 AM Microsoft Azure Service Fabric Traditional vs Microservices approach Traditional application approach A traditional app contains domain specific functionality and is normally divided by functional layers such as web, business and data. Scales by cloning the app on multiple servers/VMs/Containers. 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. App 1 App 1 App 2 © 2016 Microsoft Corporation. All rights reserved.

Microsoft Azure Service Fabric Service type Services types are composed of code/config/data packages. code packages define an entry point (dll or exe) config packages define service specific config information data packages define static resources (eg. images) Packages can be independently versioned. Service Type 1 Code Config Data <ServiceManifest Name="QueueService" Version="1.0"> <ServiceTypes> <StatefulServiceType ServiceTypeName="QueueServiceType" HasPersistedState="true" /> </ServiceTypes> <CodePackage Name="Code" Version="1.0"> <EntryPoint> <ExeHost> <Program>ServiceHost.exe</Program> </ExeHost> </EntryPoint> </CodePackage> <ConfigPackage Name="Config" Version="1.0" /> <DataPackage Name="Data" Version="1.0" /> </ServiceManifest>

Microsoft Azure Service Fabric Service Fabric Programming Models Guest executables and Containers Reliable Services Reliable Actors Bring any exe. Any language. Any programming model. Packaged as Application or as a Container. Gets versioning, upgrade, monitoring, health, etc. Stateless and stateful services. Concurrent, granular state changes. Use of the Reliable Collections. Transactions across collections. Full platform integration. Stateless and stateful actor objects. Simplified programming model. Single Threaded model. Great for scaled out compute and state.
