The document discusses microservices and Azure Service Fabric, explaining that microservices break applications into small, independent processes that communicate through APIs and Service Fabric is a platform for building and managing microservices applications both on-premises and in the cloud. It provides an overview of Service Fabric concepts like service types, the service lifecycle, and reliable collections.

- 6. @ITCAMPRO
- 7. @ITCAMPRO Software architecture style in which complex applications are composed of small, independent processes communicating with each other using language-agnostic APIs Microservices
- 8. @ITCAMPRO WHY WE SHOULD USE MICROSERVICES?
- 9. @ITCAMPRO If we need a system that has components that are… High decoupled Small Easy to replace Focus on doing a small task Independent deployment units Symmetrical architecture
- 10. @ITCAMPRO Evolution Maintenance is hard Adding new features is slow Changes are expensive Technology becomes the obstacle rather than enabler App Modernization
- 12. @ITCAMPRO • Service Fabric • Azure Service Fabric Why we have two different things? ?
- 13. @ITCAMPRO Service Fabric | Azure Service Fabric Microservices Cloud Azure Azure Service Fabric AWS Service Fabric On-premises Service Fabric
- 17. @ITCAMPRO Stateless •No state persisted between calls Stateful •‘A’ state is persisted between calls
- 18. @ITCAMPRO
- 19. @ITCAMPRO What can we run in Service Fabric? Service Fabric Web Sites Application Custom logic
- 20. @ITCAMPRO • Multiple programing languages (C# & Java) • Support different commucation mechanisms: –HTTP(s) –WCF –TCP –UDP • Any protocol and communication stack is supported • Capable to run a guest executable How
- 21. @ITCAMPRO
- 24. @ITCAMPRO Reliable Services Actors Stateful Stateless State State … after the call is executed State
- 25. @ITCAMPRO Reliable Services Actors Stateful Stateless State State … when GC is triggered State
- 26. @ITCAMPRO
- 27. @ITCAMPRO One UI for all environments
- 29. @ITCAMPRO • Local debugging like any other .NET application • Attach debugger to any Service Fabric Application (on-premises or cloud) • Diagnostic Events persistent in Cluster • Real time Streaming Traces (Diagnostics Events) Debugging and tracing
- 30. @ITCAMPRO
- 31. @ITCAMPRO • Low latency • High-throughput • Transactional • Can be used only with Reliable Services Reliable Collections Dictionary and Queue Replicat ed Persiste d In- memory <<servic e instance >> Asynchr onous Transacti onal
- 32. @ITCAMPRO Where collection are stored
- 33. @ITCAMPRO • Different instances of the same service can access the same Reliable Collection • Instances from different services cannot access the same collection Reliable Collection – visibility
- 34. @ITCAMPRO
- 36. @ITCAMPRO Timers and Reminders Timers Similar with .NET Called at a specific time interval Reminders Timer with persistence Trigered in all circumstances (deactivations and failovers) Concurrency Turn based concurrency Stateful Actos only
- 37. @ITCAMPRO • Context: Multiple calls to the same Reliable Actor Concurrency
- 40. @ITCAMPRO Execution flow: • Reminder Trigger • SetPrice • SetStock Concurrency
- 41. @ITCAMPRO
- 42. @ITCAMPRO Events • Send events and notifications from services to caller • Allows us be notified at different steps on when an exception occurs • Can be used only for actor-client communication
- 43. @ITCAMPRO • On Actor: – IActorEvents – Trigger our custom events • On source: – Implement callback (Event Handler) – Subscribe our Event Handler Events
- 44. @ITCAMPRO
- 48. @ITCAMPRO Fault Domains and Upgrade Domains
- 49. @ITCAMPRO Where we can control them Application • Partitioning • Replication Cluster • Fault Domain • Upgrade Domain • Naming Service • Resource Balancer • Failover Manager
