Microsoft announced GA for Managed Instance on Azure App Service, enabling legacy .NET apps to run on a fully managed PaaS platform with enterprise SLA.
Microsoft has announced the general availability of Managed Instance on Azure App Service, a fully managed platform‑as‑a‑service (PaaS) that allows legacy .NET applications to run with an enterprise‑grade service level agreement (SLA).
What Managed Instance Brings to Azure App Service
Managed Instance extends the familiar Azure App Service environment with deeper integration for classic .NET Framework workloads, providing automatic scaling, patching, and built‑in monitoring while preserving the operational simplicity of a PaaS offering.
Key Benefits for Legacy .NET Applications
- Zero‑touch infrastructure: Microsoft handles VM provisioning, OS updates, and networking without customer intervention.
- Enterprise SLA: 99.95% uptime backed by Azure’s global reliability guarantees.
- Seamless migration: Existing .NET Framework code can be deployed with minimal refactoring using familiar App Service tooling.
The service also supports integration with Azure Virtual Network, private endpoints, and Azure Monitor, enabling customers to meet strict compliance and performance requirements while keeping their legacy codebases operational.
How to Get Started
Customers can provision a Managed Instance directly from the Azure portal, Azure CLI, or ARM templates. The onboarding wizard guides users through selecting the appropriate App Service plan, configuring networking, and linking to existing Azure resources such as databases and storage accounts.
Microsoft recommends running a health check using the new Managed Instance diagnostics to verify compatibility before moving production workloads.
Managed Instance on Azure App Service delivers the reliability of a modern cloud platform without forcing a rewrite of mission‑critical .NET applications.
