The Application Load Balancer Cloudlet enables you to define several data center configuration scenarios to balance traffic among combinations of cloud and physical data sources, and quickly switch among them with the click of an activation button or API call. Requests for particular content can be directed to various data sources, by IP and geography or several http header attributes including: URL path, device characteristics, request method, and many more. Traditional methods of load balancing that focus solely on DNS (layer 3) requests lack the flexibility and control to provide seamless load balancing for more modern application architectures that require HTTP layer (Layer 7) controls. Hardware-based load balancers not only require maintenance, are limited in their ability to scale, but can also introduce inefficient management processes and delay time to market. Existing cloud-based approaches are often useful only for the IaaS services on which they are built and sometimes lack reliability that could take your app offline completely.<\/span><\/p>\n
