Subsystems and crosscutting

We recommend an architecture for IoT applications that's cloud native, microservice, and serverless based. The architecture also supports a hybrid cloud and edge compute strategy as some on-premises data processing is expected. To scale individual subsystems horizontally, we recommend the use of an orchestrator, such as Azure Managed Kubernetes or Service Fabric, or PaaS services that offer built-in horizontal scale capabilities, like Azure App Services.
