# Outdated Azure App Service Plan

## Explanation

Applications running on App Service  V2  plans may incur higher operational costs and degraded performance compared to  V3  plans. V2 uses older hardware generations that lack access to platform-level enhancements introduced in V3, including improved cold start times, faster scaling, enhanced networking options, and eligibility for commitment-based discounts.

This inefficiency often arises from legacy deployments or default provisioning choices that haven't been revisited. Without proactive review, teams may continue running production workloads on suboptimal infrastructure-paying more for less performance and missing available savings.

## Relevant Billing Model

App Service plans are billed based on:

- Instance size and tier (e.g., Premium v2 vs. Premium v3)

- Provisioned capacity (number of instances)

Additional considerations:

- Premium v2  plans do  not  support Azure Reservations or Savings Plans

- Premium v3  plans support both, enabling 1-year and 3-year commitment discounts

- Isolated v2  plans already support reservations and savings plans

As a result, Premium v2 plans may be less cost-efficient both from a price-performance and discount eligibility perspective.

## Detection

- Identify applications hosted on  Premium v2  or  Isolated v1  App Service plans

- Check whether the workload is long-running or steady-state but ineligible for reservations

- Determine whether a V3 compatibility review has been completed

- Look for performance symptoms such as slow cold starts or scaling delays

- Assess whether newer App Service features required by the workload are unavailable on V2

## Remediation

- Evaluate workload compatibility with  Premium v3  or  Isolated v2  plans

- Migrate eligible Premium v2 workloads to Premium v3 to improve performance and unlock reservation or savings plan eligibility

- Consider 1-year or 3-year commitments for predictable workloads after migration

- Update infrastructure-as-code templates and provisioning defaults to prefer V3-based plans

- Periodically review App Service plan usage to align with current Azure best practices
