Application Load Balancer : external IP outside VPC ?

Hi

I understand that you would like to use AWS load balancer with servers hosted in another providers, The answer is Yes, Here are the steps:

Application Load Balancing via IP Address

1. You can use AWS ALB to route the traffic to the Web Server by IP address of servers IP addresses

• Supports load balancing to VPC and on-premises resources.
• Facilitates routing to multiple IP addresses and network interfaces on the same instance.
• Offers flexibility with microservice based architectures, simplifying inter-application communication.
• Supports IPv6 targets, enabling end-to-end IPv6 communication, and IPv4-to-IPv6 NAT.

2. These addresses can be in the same VPC as the ALB, a peer VPC in the same region, on an EC2 instance connected to a VPC by way of ClassicLink, or on on-premises resources at the other end of a VPN connection or AWS Direct Connect connection.

How to proceed ?

• Create Target Grouo for the Load balancer [ALB]
• Select target type is** IP addresses type**
• Select your VPC in the dropdown
• in the next step you need add the IP adress of your web server [Private IP] that must meet the IP ranges in the VPC, for this you can use site to site connection or Direct connect from the location of servers to AWS VPC
