Application Delivery Controllers \ Load Balancers Vendor List
The job of a load balancer is to distribute traffic across multiple servers. For example you can place a load balancer in front of multiple web servers or email servers. When traffic such as a web request or an email is destined for these servers, the load balancer sends the first email or web request to the first server then the next email or web request will be redirected to the 2nd server by the load balancer and so on. This will enable high availability, better performance and scalability.
Load balancers can also use other clever algorithms in order to distribute traffic. An example is If a network consists of two email servers where one is old and slow and the other is new and powerful, a load balancer can be configured to send more emails to the powerful server.
Load balancers can detect when a server has gone down and come back online again which is a feature known as server health monitoring. Some load balancers come with built in IPS and other application layer security features as well as SSL off-loading, compression and caching functionality. The combination of a load balancer and these other features built in is now termed as Application Delivery Controllers.
