AzureDeprecations & retirementsTeam planSeverity: highazure.spring-service-instance

All Azure Spring Apps plans (Basic, Standard, Enterprise) retire on March 31, 2028; migrate to Azure Container Apps or AKS

What LeftSize checks

Detect Azure Spring Apps service instances. All plans (Basic, Standard, Enterprise) entered a three-year retirement period on March 17, 2025 and are retired on March 31, 2028. After that date you no longer have access to your workloads. Migrate to Azure Container Apps (recommended) or AKS.

Why it matters

Missed retirement and end-of-support dates turn into forced upgrades, outages or extended support charges at a moment you did not choose.
