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.
August 11 this year, organized by theAWS Summit in New YorkOn, Amazon CTO Werner Vogels noted that the new load balancer is significantly better:
We use some of the earliest closed beta users there heard was, ALB AWS only than the original Classic Load Balancer faster, and you will see a significant reduction in costs. Generally it can reach 10% or more.
Of course, other cloud service providers has also been a similar product. Microsoft's Azure providesApplication Gateway (Application Gateway)Products, Goole also provides aBased on HTTP and HTTPS equalizer.
ALB has with other AWS products Auto Scaling, ECS, CloudFormation, CodeDeploy and Certificate Manager, etc. with the use, with the Elastic Beanstalk and AWS Config integration is implementation. Original Elastic Load Balancer equalizer, now known as Classic Load Balancer, is still available. be usable Load Balancer Copy Utility Existing Classic Load Balancers migrate to ALB.
