Running Microservices on Azure Service Fabric by Michele Tedesco

Running Microservices on Azure Service Fabric by Michele Tedesco

Modern Cloud Applications and Microservices are a trending topic among Development Teams, as they are supposed to enable innovation, digital transformation, and reduce time to market of business capabilities.

Azure Service Fabric is Microsoft's microservice platform and has seen rapid uptake with customers as well as internal Microsoft teams.

In the session I would like to cover the latest updates and capabilities for developing microservice applications with Azure Service Fabric, whether you bring an existing executable, or use the "Reliable Services and Actors" programming model.

  20. Queues Storage Stateless Services Pattern Front End (Stateless Web) Stateless

    Middle-tier Compute Cache • Scale stateless services backed by partitioned storage • Increase reliability and ordering with queues • Reduce read latency with caches • Manage your own transactions for state consistency • More moving parts each managed differently Load Balancer
  21. Stateful Middle-tier Compute Stateful Services Pattern Simplify design, reduce latency

    Front End (Stateless Web) • Application state lives in the compute tier • Low Latency reads and writes • Partitions are first class at the service layer for scale- out • Built in transactions • Fewer moving parts • External stores for exhaust and offline analytics Load Balancer Cold Data Stores For Exhaust (Optional)

    (Services) • 1 service instance per VM • Slow deployment & upgrades • Slow scaling of roles up/down • Emulator for development • Many microservices per PC/VM • Fast deployment & upgrades • Fast scaling of microservices up/down • OneBox cluster for development
