Configuring AWS Elastic Load Balancers


In this lesson, you will learn how to setup an Elastic Load Balancer for your nodejs servers. You will also learn how to configure the load balancer with servers in different availability zones, using nodejs servers that do not require root access to bind to port 80 or 443, and are not publicly accessible via the internet. You will learn how to use health checks to ensure your servers are removed from service when not responding properly and be automatically added back to the load balancer when functional again. Finally, I show you how to understand the metrics provided by the ELB to troubleshoot problems with both your backend servers and the ELB itself.
