Terms in this definition
- App Service
Managed PaaS hosting for web apps and Web App for Containers, run in a sandbox without OS access. Deployment slots and autoscale start at the Standard tier.
- FIRST
A DAX function available only inside visual calculations. It fetches the value at the start of one axis of the visual's matrix, which makes it handy for comparing each point with the first; its opposite is LAST.
- LSDOU
The sequence in which Group Policy is processed: the local policy first, followed by site, domain and organisational unit policies. The nearest, last-processed setting takes effect unless Enforced or Block Inheritance alters that.
- Authentication
Checking an identity claim made by a person, device or app, for instance by asking for a password plus an extra factor. Authorisation only happens once this step has succeeded.
