To better handle the incoming traffic from various digital devices, you are planning to implement a new routing system where requests which have a URL of /api/android are forwarded to one specific target group named “Android-Target-Group”. Deleting ELB won’t delete the instances registered to it. AWS Cheat Sheet – AWS Elastic Load Balancing (ELB), Distributes incoming application or network traffic across multiple targets, such as. Metric collection. Listeners per load balancer: 100 †. This is usually done by another AWS service known as Amazon CloudFront. References: Network Load Balancer currently supports 200 targets per Availability Zone. Let’s unwind that example. The nodes of an internal load balancer have only private IP addresses.
