Join Brandon Rich for an in-depth discussion in this video Understand AWS elastic load balancers, part of Amazon Web Services: Deploying and Provisioning.
- [Narrator] Let's take a look at how AWS…can distribute traffic across multiple instances…using elastic load balancers.…Imagine you have a web application on one instance.…The security group exposes web traffic ports to the world.…When your app starts to receive more traffic…than it can handle, you may wish to distribute the traffic…across multiple instances of your web server.…It's time to introduce an elastic load balancer.…An ELB can be configured to evenly distribute web traffic…across each instance.…Now, instead of making HTTP requests directly…to an EC2 instance, new users make requests…to the address of the load balancer…which conveys those requests to the underlying instances.…
In terms of network security, the EC2 security group…should be configured to allow only web traffic…from the elastic load balancer.…Meanwhile, the ELB itself has a security group…which should be configured to expose your web traffic.…The app still has a single interface or web address,…the ELB now, instead of the single EC2 instance,…
