Overview

• Azure service fabric is microservice framework and container orchestrator.
• Solves following problems:
  • Service instance communication
  • Service discovery
  • Telemetry
  • Provision, rolling upgrade
  • Testing locally
  • Manage downtime and instance failure
  • Scaling in and out

Kubernetes vs Service Fabric

• SF only runs Linux experiment as of now.
• Kubernetes is container only. vs SF can run containers, Native services, Guest Executables.
• Both are language agnostic.
• SF allow programmatic control using java and .net
• SF provide out of box programming model. SF support actor programming model.
• Handling state in SF is easy. Support stateful applications.
• SF recovers failed nodes in 10 to 15 seconds vs Kubernetes takes 5 minutes.
• Cost of both system is same.

Azure Functions

We can write microservice with Azure Functions as well.

• React to external events
• Can be called as REST service
• Run on a scheduke
• Event driven
• Good alternative for ASF and AKS
• Easiest to start with
• Easy to perform background tasks
