16. Ways to Run Functions Azure Stack Consumption App Service Plan

Ways to Run Functions
Consumption
Serverless
App Service Plan
Free, Basic, Standard, Premium
App Service Environment
Network Isolation
Azure Stack
On Premises
Azure Functions Runtime (preview)
Functions on your Server
Pay only for what you use! Metering is per execution and per GB Second.
Your own dedicated cloud environment with network isolation for apps, higher scale, and the ability to connect securely to local vNets.
Leverage cloud innovations in on-premises infrastructure. Azure Stack brings the power of Azure to your own data centers.
Run your Azure Functions on your local server (without the rest of Azure)
All the advantages of Functions with the SLA and ‘always on’ features of an App Service Plan.

17. Consumption Plan The Consumption Plan option
Pay for what you use without the need to reserve compute resources.
Function Apps are assigned to compute processing instances that are scaled dynamically by the platform.
Functions can have multiple parallel executions minimizing the total time needed to process requests.
Cost is driven by the number of executions and by accounting for memory size used and total execution time across all functions in a Function App as measured in gigabyte-seconds.
Selection guidance
Good option if your functions run at elastic scale with potentially intermittent executions.

18. App Service Plan The App Service Plan option
Function Apps run on dedicated VMs, just like Web Apps work today for Basic, Standard, or Premium SKUs.
Dedicated VMs are allocated to your apps and they are always available whether code is being actively executed or not.
Selection guidance
Good option if you have existing, under-utilized VMs that are already running other code or
Good option if you expect to run functions continuously or almost continuously

19. What is the “Functions” programming model?
Function as the unit of work
Functions are executed; they start and finish
Functions have triggers
Functions can have inputs and outputs (bindings)
