This can occur when applications are deleted, migrated, or retired, but the associated App Service Plan remains active. Without ongoing workloads, these idle plans become silent cost contributors - especially in higher-cost SKUs like Premium v3 or Isolated v2. In large or decentralized environments, unused plans can accumulate quickly if cleanup is not automated or routinely enforced. These idle plans offer no functional value but continue to consume compute resources and generate operational expense. ## Billing model The pricing dimensions that drive this cost. - App Service Plans are billed based on: - Instance size and tier (e.g., Premium v3, Isolated v2) - Provisioned capacity (number of instances) - Charges apply even if no applications are deployed to the plan - Shared tier plans (e.g., Free or Shared) are not affected, but most production workloads use dedicated SKUs ## How to detect 4 checks to find it in your estate. - Identify App Service Plans with zero deployed applications - Determine whether the plan was previously associated with a workload that has been deleted or migrated - Review tagging, naming, and ownership metadata to validate whether the plan is still in use or intended for future deployments - Flag plans in higher-cost tiers without active utilization ## How to fix 4 ways to remove the waste. - Decommission App Service Plans with no active applications unless a future use case is explicitly confirmed - In cases with low utilization, consider consolidating multiple lightly used plans into a single plan to reduce spend - Establish governance practices to routinely identify and remove orphaned plans after application lifecycle events - Update provisioning workflows to clean up unused plans automatically or via policy ## Documentation Vendor references for pricing and configuration. - [Azure App Service Plans Overview learn.microsoft.com](https://learn.microsoft.com/en-us/azure/app-service/overview-hosting-plans) - [App Service Pricing azure.microsoft.com](https://azure.microsoft.com/en-us/pricing/details/app-service/) ## Related inefficiencies [Browse the library](https://www.pointfive.co/efficiency-hub) - Azure App Service CER-0306 ### [Non-Production App Service Plans Running Higher Tiers During Off-Hours](https://www.pointfive.co/efficiency-hub/inefficiencies/non-production-app-service-plans-running-higher-tiers-during-off-hours) Azure App Service Plans define the compute resources allocated to web applications and are billed continuously based on their pricing tier - regardless of whether the hosted apps are actively serving traffic.
