Abstract image


Most on-premises DNS solutions don’t scale nearly enough to support today’s flourishing number of applications and burgeoning application footprints.


Time-consuming to deploy

Traditional load balancing can be laborious for organizations to set up and scale to support all applications—especially those running in cloud or edge locations.


Difficult to integrate

Maintaining load balancing functionality for modern apps is burdensome and not easy to integrate into CI/CD pipelines and critical development workflows.


Lack of reliability

Organizations with more complex environments—distributed apps and workloads, numerous locations and endpoints—struggle to deliver reliable app experiences and performance.

No redundancy

Traditional DNS lacks zero-touch failover and the ability to dynamically fail applications over to designated or available instances.

Why F5 Distributed Cloud DNS Load Balancer?

Speed and simplicity

Seamlessly integrate into critical development workstreams and DevOps pipelines, allowing for configuring of critical DNS load balancing services in just a few clicks.
