When a new server comes online in the data center, a load balancer will proportionately remove load from other servers and increase the utilization of the new hardware. Software-based load balancing services allow a CDN to scale load balancing capacity quickly without the bottlenecks present when using physical load-balancing hardware.

Cloudflare Load Balancing runs at each of our data centers across 200 cities worldwide and is powered by our DDoS-resilient DNS — the fastest Authoritative DNS in the world. Our global Anycast network is 15x bigger than the largest DDoS attack ever recorded and ensures that traffic continues to get routed even under stress. Traffic Manager is a DNS-based traffic load balancer that enables you to distribute traffic optimally to services across global Azure regions, while providing high availability and responsiveness. Because Traffic Manager is a DNS-based load-balancing service, it load balances only at the domain level. set load-balance group G sticky proto enable. Troubleshooting. Back to Top. You can verify the Load-Balancing configuration and status with the following commands: show load-balance status show load-balance watchdog show load-balance config. The main and Load-Balancing routing tables can be displayed with the commands below: show ip route show Cloud-based DNS providers usually offer load balancing services for free or at minimal cost. You can be up and running in a matter of minutes, with limited maintenance. DNS load balancing doesn’t require any extra lookups, because it happens through your authoritative DNS provider. Round robin DNS uses a DNS server, rather than a dedicated hardware load balancer, to load balance using the round robin algorithm. With round robin DNS, each website or service is hosted on several redundant web servers, which are usually geographically distributed.

Jan 06, 2020 · Internal Load Balancing: Internal load balancing is nearly identical to network load balancing but can be leveraged to balance internal infrastructure.

Definitely use the multiple NS records, as TCP becomes more common for DNS just let it load-balance itself. Re-inventing the wheel is painful for a reason. – cpt_fink Feb 18 '15 at 4:34 Multiple DNS servers do offer redundancy and prevent total failure, but a downed DNS server would still cause name resolution delays. – 200_success Feb 18
