DNS Traffic Management
Maintainability, availability, and disaster recovery planning are critical elements in today’s Internet-driven industries. Progressive eBusiness companies must have IT infrastructures and business processes to assure IT systems maintain 100% availability, as downtime even in the order of minutes can mean the loss of tens of thousands in revenue dollars. These concerns are well understood in today’s advanced IT operations and successful companies continuously strive to address these needs.
UltraDNS Traffic Management solution provides a set of tools allowing IT administrators to define load balancing configurations for content servers residing in one or more geographic locations. The Traffic Management Solution manages traffic directed to the servers by dynamically changing the responses to DNS requests. Load balancing is performed based on dynamic metrics obtained from the host servers on a continual monitoring basis. The UltraDNS Traffic Management solution is not a single application, but combines the capabilities of several existing UltraDNS systems to control traffic, manage site failures, and optimize web content systems.
The Traffic Management solution is an important tool in distributing and shaping the query responses with UltraDNS geographically distributed nodes. The solution:
- Allows automatic failover to alternative content servers should there be any technical or operational failure or a catastrophic event
- Provides the ability to route user to content servers that are geographically close by
- Improves performance of the existing server resources by preventing “busy” servers from overloading and increasing traffic to “less busy” servers, thus maximizing overall utilization of the content network
The UltraDNS monitoring and automatic IP fail-over service, monitors customers’ mission critical web presence. In the event of a failure, it redirects traffic to a “hot” standby ensuring a customer’s users and businesses are unaffected. Utilizing a network of monitoring servers throughout the Ultra DNS global DNS network mesh, customers are able to select specific records for monitoring and SiteBacker does the rest.
The UltraDNS traffic redirection service provides a tool to enhance Internet site performance and reliability without costly equipment purchases and software/hardware maintenance. Directional DNS service optimizes network efficiency across geographic zones by creating a customized query response that directs traffic to specific locations from each zone of the company's global mesh of replicated fail-safe servers.
Weighted Load Balancing (WLB) service optimizes traffic distribution and network performance at the DNS level. Intelligence at the DNS level allows the network to function in its most effective capacity, distributing internet traffic automatically among multiple servers based on preset parameters. Utilizing advanced DNS based Load Balancing allows enterprises to reap the benefits of traffic management without deploying additional hardware or software. Enterprises use WLB to enhance traffic management patterns to increase service application performance, scalability and resiliency while reducing or sharing costs incurred for multiple data centers typically used as backups.
