¿Qué es Private endpoint, network load balancer?

También llamado: private endpoint · network load balancer

Definition 18.2 Networks, Hardware and Trading Infrastructure · Capítulo 18 — Private Connectivity to Crypto Venues

A private endpoint is a network interface that a provider places in a customer’s virtual network, in chosen zones, through which the customer reaches another party’s service privately, without routing between the two networks. A network load balancer is the provider’s service that receives connections on one address and spreads them over target machines, at the level of TCP or UDP; a private-endpoint service is typically exposed through one.

Three ways from a firm’s instance to a venue in the same cloud region, schematically: peering between the two virtual networks, a private endpoint (an interface in the firm’s network, a load balancer in front of the venue’s gateways), and the public endpoint through an edge network.

The endpoint in the wrong zone, schematically: the venue’s gateways in az1, its endpoint’s interfaces in az1 and az2, the firm’s instance in az4; the firm’s packets enter the interface in az2 and cross to the gateways through the load balancer. No placement of the endpoint keeps this path in one zone (); moving the instance to az1 does. Zone labels are identifiers, not names.

No placement of the endpoint keeps this path in one zone (Proposition 18.3); moving the instance to az1 does. Zone labels are identifiers, not names.
