Terms in this definition
- WHERE
Limits a SELECT, UPDATE or DELETE to just the rows meeting a condition. Omit it, and the statement hits every row.
- ExpressRoute circuit
The logical link between on-premises and Microsoft, provided by a connectivity partner or through ExpressRoute Direct. A service key identifies it, and it carries both Microsoft and private peering.
- Availability zones
Separate physical datacentre locations inside one region. Placing VMs in at least two of them earns a 99.99% SLA.
Related terms
- Connectivity provider
Telecoms partner that, given the circuit's service key, provisions ExpressRoute at a peering location; with ExpressRoute Direct you connect without one.
- ExpressRoute Local
Lower-cost circuit option whose reach stops at the one or two Azure regions close to its peering location. Unlimited data, with egress bundled, is the only billing choice, and Global Reach is unsupported.
