This thread  was started more than a year ago, asking for when Amazon Web Services will add support for HTTP/2  into their ELB. In addition to that, people are also asking, how to configure ELB to support multiple SSL certificates. AWS support team has been reluctant on giving out any specific details on when both of these features will be available, citing: I've verified that the ELB team is aware of the interest in ELB supporting HTTP/2. Please keep an eye on What's New from Amazon Web Services: http://aws.amazon.com/new/ for any updates. What is HTTP/2? HTTP/2 is a replacement for how HTTP is expressed “on the wire.” It is not a ground-up rewrite of the protocol; HTTP methods, status codes and semantics are the same, and it should be possible to use the same APIs as HTTP/1.x (possibly with some small additions) to represent the protocol. HTTP/2 protocol is supported by major modern browsers including IE11, Edge 13, Firefox 47, Chrome 52, Safari 9.1, Opera 38, ...

Amazon Web Services announced cross-zone load balancer, which supposed to further improve distribution of requests amongst all the instances behind the load balancer. If you enable cross-zone load balancing, you no longer have to worry that clients caching DNS information will result in requests being distributed unevenly, resulting more even load. I went ahead and tried it out myself. Enabling the Cross-Zone Load Balancing goes through the command line, you need to download and configure the tool on your computer before proceeding. Read the instructions how to download, install and configure ELB command line tools here .

Amazon Web Services announced this long-time waited update to its OpsWorks by adding support to Elastic Load Balancer . During AWS Summit 2013 New York it was mentioned several times that ELB support will be added soon  - I am glad they kept their word. Until now, developers taking advantage of Amazon OpsWorks were forced to bring up one instance as HAProxy; but you can now add Elastic Load Balancing (ELB) to your OpsWorks application stacks and get all the built-in capabilities ELB is known for, including automatic scaling across availability zones. Combining this feature with Amazon Route53 latency based routing , and you have highly available, redundant, scalable application. Related article: AWS OpsWorks supports t1.micro instances
