Terms in this definition
- ELT
Extract, load, transform: raw data lands in the target system first and is transformed there. See ETL for the opposite order.
- SKU
The size or tier of a service, for example a VM size or the Premium tier of ACR.
- PATH
Parent-child hierarchies in DAX rely on this function. For each row it builds one delimited text value listing the IDs of the row's ancestors, top level first and ending with the row's own ID, which PATHITEM, PATHLENGTH and friends can then pick apart.
- Azure Load Balancer
Layer-4 load balancer operating within a region, with zone redundancy on the Standard SKU; it has no WAF, doesn't terminate TLS and can't route by URL.
- VXLAN
Encapsulation of layer 2 frames in UDP on port 4789. Gateway Load Balancer chains NVAs with it, and Azure Extended Network uses it to carry a stretched subnet between its pair of appliances.
Related terms
- Public IP address
Resource in Azure for an IPv4 or IPv6 address routable on the internet, attached to a NIC, firewall, gateway, load balancer or Bastion host. Allocation, zone support and default security depend on its SKU.
