DNS Load Balancing is one of those DNS Hosted Services that provide a more efficient means for users to access the Internet. Through the use of DNS management tools, DNS security and DNS uptime are optimized.
DNS stands for Domain Naming System, the hierarchical system that links domain names of Internet entities to the numbers that tells network equipment the network address of the relevant device somewhere in the world.
Load balancing is the provision of even work distribution over redundant computer servers. The purpose is to create optimal throughput, maximize resource use, avoid server overload, and minimize server response time. The combination of load balancing with multiple computing components also increases system reliability.
So, DNS load balancing combines these two concepts to perform one integrated function that takes a domain name entered by the user in text format, redirects the request to a DNS server that is free to handle the request and returns the numerical response to allow the user to access the device that represents that domain. DNS uptime is maximized, DNS security is improved, and DNS management tools allow the DNS Services to be monitored and fine-tuned, all within one set of DNS Hosted Services.
An organization that makes use of a DNS Load Balancing solution benefits in many ways. Network traffic management for DNS Services allows improved delivery of information to users and to data centers elsewhere in the organization. DNS Load Balancing can be implemented via a round-robin method, where DNS requests are delivered to DNS servers in order by a queue, or by a geographical scheduling method, where network traffic levels and geographic location are the factors used by DNS Management Tools to determine the routing of a DNS request to a DNS server.
Persistent DNS routing can also be set up, so that all additional related DNS requests from the same user are processed by the same DNS server, a process that takes advantage of the DNS cache on a server to quicken the processing of the requests. This DNS service can also be used to store on email servers details about emails from or to certain domains, a feature which also enhances DNS security.
Customers who take advantage of these DNS Services for DNS Load Balancing will find that they will then have networks that provide optimal delivery of services to the users across the globe, while ensuring optimal levels for both DNS security and DNS uptime.
