Load Balancing is a technique (usually performed by load balancers) to spread work between many computers, processes, disks or other resources in order to get optimal resource utilization and decrease computing time. A load balancer can be used to increase the capacity of a server farm beyond that of a single server. It can also allow the service to continue even in the face of server down time due to server failure or server maintenance.
If you use multiple CDNs to serve your content, you are well aware of the benefit of quick content delivery. However, what happens if one of your CDNs goes down? Without load balancing, that fast load time can turn into downtime in an instant. Luckily your trusty DNS provider is here to help.

There are more people on earth than total IPv4 addresses, and they're expected to run out by the end of 2011. Preparing for the transition now can help you maintain business continuity during the changeover while taking advantage of immediate business benefits.
If your organization's servers run applications that are critical to your business, chances are that you'd benefit from an application delivery solution. Today's Web applications can be delivered to users anywhere in the world and the devices used to access Web applications have become quite diverse.
At a projected market of over $4B by 2010 (Goldman Sachs), virtualizationhas firmly established itself as one of the most importanttrends in Information Technology. Virtualization is expectedto have a broad influence on the way IT manages infrastructure.Major areas of impact include capital expenditure and ongoingcosts, application deployment, green computing, and storage.
The idea of load balancing is well defined in the IT world: A network device accepts traffic on behalf ofa group of servers, and distributes that traffic according to load balancing algorithms and the availabilityof the services that the servers provide. From network administrators to server administrators to applicationdevelopers, this is a generally well understood concept.
Application Delivery Controllers understand applications and optimize server performance - offloading compute-intensive tasks that prevent servers from quickly delivering applications. Learn how ADCs have taken over where load balancers left off.
Internal testing only allows you to see potential issues from within your own controlled environment, and does not test for the countless different scenarios in which a customer could be accessing your site. Find out the benefits of external load testing.
