What media should I use to keep backup? Which packages should be on my server? Who monitors my App? What size of servers should I buy? How often should I backup my server? How can I increase server utilization? How can I scale my app? Who has physical access to my servers? Which OS should I use? Do I need secondary network connection? Are my server in a secure location? What happens if the power goes out? Who monitors my Servers? Do I need a UPS? What storage I need to use? How many servers do I need? How can I dynamically configure my app? It takes how long to provision a new server? How often should I patch my servers?

Ways to Run Functions Azure Stack Consumption App Service Plan 1/3/2019 9:40 AM 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. © Microsoft Corporation. All rights reserved. MICROSOFT MAKES NO WARRANTIES, EXPRESS, IMPLIED OR STATUTORY, AS TO THE INFORMATION IN THIS PRESENTATION.

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.

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
