Terraform module to add on-premises servers to ALB for Alibaba Cloud

terraform-alicloud-add-on-premises-servers-to-alb

English | 简体中文

This Module designs a cloud-based delivery network for IDC seven-layer applications, including:

1. Building a high-availability dedicated network between the cloud and IDC through ECR （Express Connect Router）
2. Enabling the migration of seven-layer public network entry points of IDC servers to the cloud through ALB (Application Load Balancer).
