English text:AWS Launches Application Load Balancer

Amazon has released its new load balancer products,Application Load Balancer (ALB). ALB is a new intelligent load balancer, for those who run the user-based HTTP services, it can significantly reduce the cost of load balancing.

ALB is located on the seventh layer of the OSI model load balancer so that it can based on the content of the network packet network packet routing to a different back-end services. Existing load balancers are mostly located on the fourth layer of the OSI model for TCP / UDP equalizer. These equalizers difference is, ALB will check the content of network packets, and sends the packet to the appropriate network services. Currently, ALB support URL for routing traffic based on independent rules defined up to 50 of the.

For users who run a fine-grained backend services, the use of ALB is a benefit. Unlike for each service to run an elastic load balancer, a plurality of back-end services that ALB can balance network traffic. For example, it contains & ldquo; / api & rdquo; URL and contains a & ldquo; / signup & rdquo; URL will be routed to different back-end services.

In future updates, ALB will very likely have a routing function according to any HTTP header information. Jeff Barr from Amazon suggests such improvements. He mentioned that, & ldquo; Over time, we plan to provide additional routing method. & Rdquo;

In addition to support for standard HTTP route, ALB also supports WebSockets and HTTP / 2.
