Inbound Link Balancing and Failover Using DNS. You can use DNS to balance inbound traffic among multiple links. Associate your domain name (or names) with multiple IP addresses, each of which represents an external interface. When the DNS request for the domain name is resolved, all of these IP addresses are included in the answer.

For advanced DNS load balancing techniques, see . Advanced DNS traffic management using the BIG-IP LTM, on page 2-1. Overview of DNS. At the most basic level, Domain Name System, or DNS as it is commonly known, is an Internet service that maps domain names into IP addresses and is an essential component of any network. There are two types of DNS Cloud load balancing is the process of distributing workloads across multiple computing resources. Cloud load balancing reduces costs associated with document management systems and maximizes availability of resources. It is a type of load balancing and not to be confused with Domain Name System (DNS) load balancing. When BIG-IP DNS considers a resource unavailable, BIG-IP DNS attempts to select the next resource based on the current load balancing method. About virtual server dependency Within BIG-IP DNS, you can configure a virtual server to be available based on the availability of other virtual servers. DNS Failover – negatively impacts RTO. DNS-based Failover solutions suffer from the same limitations as DNS-based Load Balancing solutions. However, in disaster recovery scenarios, the effects of the inherent latency of DNS-based solutions are even more severe—markedly lengthening RTO (Recovery Time Objective, or the amount of time a business can function without the system’s availability). Jul 10, 2018 · DNS Server Load Balancing is an architecture where Domain Name System (DNS) servers are placed behind a Server Load Balancing system. DNS requests are distributed, or load balanced, across a group of DNS servers. This provides a highly available and high performing DNS infrastructure. DNS technologies provide a built-in load balancing solution based on the DNS protocol specification. Multiple Scaling DNS Services with BIG-IP DNS for Service Providers F5 offers a hyperscale and secure DNS solution for service providers that allows for faster web browsing and reduced latency. This improves subscribers’ user experience and leads to reduced churn and increased revenues.

DNS Load Balancing distributes your query traffic across multiple resources based on resource availability and performance. Load balancing is commonly used to manage traffic flow between redundant systems, such as web servers or CDN services. All systems in the configuration are always “live” and each handles a share of incoming traffic.

Feb 19, 2020 · How to improve DNS load balancing. The best way to improve DNS load balancing and avoid such corner cases, is to “teach” it about your network topology. Instead of routing based on geographical “closeness,” we would use routing based on latency/network topology “closeness,” (the lower latency to the PoP → the closer it is). DNS Services provides managed DNS and geographical load balancing services on a global DNS network.

Figure 2. Load Balancing DNS Servers Entity Model. To configure a basic DNS load balancing setup, see Setting Up Basic Load Balancing. Follow the procedures to create services and virtual servers of type DNS, naming the entities and setting the parameters using the values described in the previous table.
