Nova Destinations are highly available DNS endpoints for you to direct traffic to. They serve several purposes, from ease of use to allowing you to deploy highly available systems.
Destinations are Nova managed DNS addresses (FQDNs) which point to one or more IPs, Nodes or Tags on your system.
They are designed to allow you to easy and powerfully scale your DNS and provisioning by using the Nova network to serve DNS, and to set destinations based on Tags and Nodes instead of statically.
This serves several purposes, from ease of use to allowing auto-scaled Nova Nodes. Additionally, it allows you to route traffic to multiple datacenters, or to a DR site in the event of a primary failure.
Destinations allow you to route traffic to nodes that are online - meaning that if you have a datacenter, Node, or backend failure we can move your traffic off the datacenter.
You are also able to run active/active in multi-cloud or multi-AZ environments, and use a primary/backup configuration to route traffic to disaster recovery centers.
This is all dynamic, meaning Nova takes care of it automatically for you.
Destinations also allow you to send traffic to a tag group, which can automatically scale. In this way you can have many active Nova nodes that dynamically scale out and in to handle your incoming traffic.
Alternatively you can use Destinations to send active traffic to multiple endpoints at once.
Nova provides a 100% uptime SLA on Destination DNS queries, via our DDoS-protected DNS service provider.
This is delivered via an extremely high performance DNS network, with instant global propagation, across a wide-spread, global, anycasted DNS network.
The network is powered by NS1, the same network powering LinkedIn, Dropbox, Salesforce and many more.
