Load Balancers


Load balancers are setup in front of multiple servers to distribute the load between each server. It does require file replication because each server needs to have the exact same information.

An example of this would be two dedicated web servers and a database server. The load balancer would split traffic in half to not overwhelm one web server. The web server would then talk with the database server. Database servers can't be replicated so they can't be a part of the load balancer group.

Load balancing is used when one web server cannot handle all the traffic the site(s) are getting. We always recommend upgrading to a larger server before moving to load balancing because of cost. But some customers have enough traffic that even the largest servers can't handle which is where load balancing comes in. Load balancing is also an option for high availability because it ensures if one server goes down the site remains up.

Simply put, work gets done more efficiently when resources are not used to their capacity and as a result user response times are generally better. The best reason is often times failover. Failover refers to the ability of a system to remain operational while one or more components have failed or gone down.

People opening a new connection to your website will not notice because the load balancer will realize that the one node is not responding and will route all requests to the other two nodes until the first one is responsive again. Failover is also useful for maintenance.

If something has to be upgraded across all nodes, then one node can be taken down at a time to be upgraded without any downtime for whatever service the cluster may be hosting.

Allow your network administrators to have some peace of mind and users to keep on working with our powerful load balancers here at MacMall!
