Terms in this definition
- Traffic Manager
A global traffic router working purely through DNS, with methods such as priority, weighted, performance and geographic, for any protocol. HTTP traffic never passes through it and it caches no content.
- DNS
The system that turns names into addresses. In Azure, private endpoints depend on private DNS zones, which are queried through 168.63.129.16.
- ALL
A DAX function that ignores any filters and gives back every row of a table or every value of the named columns. Used within CALCULATE, it works as a modifier that clears filters, although REMOVEFILTERS states that intent more clearly where it is available.
