Server load balancing is a method for improving the availability and performance of software applications that are run across multiple servers. This method boosts application availability by routing client request traffic away from servers that are congested or malfunctioning, and elevates performance by balancing request traffic across healthy servers so that no one server is over-burdened.
Server load balancing is especially important for mission critical applications that handle a high volume of requests. In high traffic contexts such as popular websites and web-based applications, request traffic typically must be balanced across servers in multiple geographically dispersed datacenters.
Many of today's leading web properties and online businesses are eschewing conventional hardware-based server load balancing and instead using Akamai's cloud-based server load balancing solution.
Internet-Centric Server Load Balancing from Akamai
Akamai operates the world's largest network for accelerating web content and web application delivery to any device, anywhere. Among the services that we offer is Global Traffic Management, a DNS-based, Internet-centric server load balancing solution for high-traffic web properties that serve content and applications from multiple datacenters. With this cloud-based solution, Akamai's global network of name servers is used to direct end users' requests to the optimal datacenter, based on real-time Internet conditions as well as conditions at our clients' datacenters.
Akamai's intelligent name servers can apply a range of routing logics in real time, from simple failover logic that directs requests to an alternative datacenter when there is a failure at a primary site, to sophisticated performance maximizing logic that applies network optimization algorithms and even allows for server-specific load balancing within a datacenter. The Akamai global network of intelligent name servers is fault-tolerant and backed by a 100% SLA.
