This topic describes how to configure HTTPS for Application Load Balancer (ALB ) to achieve encrypted communication.
As a large number of enterprises migrate their services to the cloud, high security of cloud services is demanded, especially by governments and financial enterprises. To ensure service security, more and more enterprises require encryption for both frontend communication and backend communication. This requires ALB to ensure communication security when clients send requests to ALB and when ALB forwards requests to backend servers.
ALB supports HTTPS encryption to ensure communication security when clients send requests to ALB and when ALB forwards requests to backend servers.

- In the top navigation bar, select the region where the ALB instance is deployed.
