SYNOPSIS

az appservice subcommand [options]

az appservice is a subcommand of the Azure CLI that manages Azure App Service plans and environments. App Service plans define the compute resources and pricing tier for hosting web apps, API apps, mobile backends, and function apps.
Plans determine the region, number of VM instances, instance size, and pricing tier (Free, Shared, Basic, Standard, Premium, Isolated). Multiple apps can share the same plan, sharing the allocated compute resources.
App Service Environments (ASE) provide fully isolated, dedicated environments for running App Service apps at high scale, with direct VNet integration and private endpoints.

PARAMETERS

plan list

List all App Service plans.

plan show

Get details of a plan.

plan create

Create a new App Service plan.

plan update

Modify plan settings or scale tier.

plan delete

Remove an App Service plan.

list-locations

List regions supporting App Service.

ase list

List App Service Environments.

ase show

Get ASE details.

ase create

Create an App Service Environment.

--name name

Plan or ASE name.

--resource-group rg

Resource group containing the resource.

--sku sku

Pricing tier (F1, D1, B1, B2, B3, S1, S2, S3, P1v2, P2v2, P3v2, etc.).

--is-linux

Create a Linux plan.

--number-of-workers count

Number of instances to allocate.

--location region

Azure region.

CAVEATS

Deleting a plan fails if it still contains apps. Free and Shared tiers cannot scale out. Linux and Windows apps cannot share the same plan. App Service plans in different tiers have different feature availability (custom domains, SSL, deployment slots). Scaling operations may take several minutes.

HISTORY

Azure App Service evolved from Azure Web Sites, which launched in June 2012 as Microsoft's first PaaS web hosting service. It was renamed to Azure App Service in March 2015 when it unified Web Apps, Mobile Apps, Logic Apps, and API Apps. App Service on Linux was introduced in 2017. App Service Environment v3 launched in 2021 with improved performance and simplified networking.
