Release Notes: F5 DNS Load Balancer Cloud Service

Product description

The DNS Load Balancer Cloud Service will provide a highly performant global DNS based load balancing platform in the cloud. Customers are able to configure a DNS based load balancer that receives incoming requests for a fully qualified domain name, and redirects those requests to a host or application address that lives inside a public or private cloud or data center. The service can make intelligent decisions about where to direct these requests based on things like availability of the hosts in the configured server pools, the performance of those hosts, or the geographic location that the particular request was sourced from. The supported protocols for performance and availability monitoring are HTTP/HTTPS, UDP, and TCP.


This release of the F5 DNS Load Balancer Cloud Service is considered a “Preview Service” under the F5 Cloud Services Subscription Terms. As such, the DNS Load Balancer Cloud Service is provided on a Preview Service-basis for a limited time for your internal demonstration, testing, or evaluation purposes only and not for use in a production environment. This also requires that you not submit any personal information (such as a person’s name or identification number or location data) to the Preview Service. For more details, please refer to the F5 Cloud Services Subscription Terms.
