Operating system functionality on Azure App Service, which describes the common baseline operating system functionality that is available to all apps running on Azure App Service. This functionality includes file,
network, and registry access, and diagnostics logs and events.
All Azure Web Apps (as well as Mobile App/Services, WebJobs and Functions) run in a secure environment called a sandbox.
Each app runs inside its own sandbox, isolating its execution from other instances on the same machine as well as providing an additional degree of security and privacy which would otherwise not be available.
