+## Introduction
+<!-- DOCS_DESCRIPTION_CN -->
+本示例用于实现解决方案[ALB 实现跨地域负载均衡](https://www.aliyun.com/solution/tech-solution/alb-acrlb), 涉及到涉及到专有网络（VPC）、交换机（VSwitch）、云服务器（ECS）、云企业网(CEN)、应用型负载均衡（ALB）等资源的创建。
+<!-- DOCS_DESCRIPTION_CN -->
+
+<!-- DOCS_DESCRIPTION_EN -->
+This example demonstrates the implementation of the solution [Implementing Cross-Region Load Balancing with ALB](https://www.aliyun.com/solution/tech-solution/alb-acrlb). It involves the creation, configuration, and deployment of resources such as Virtual Private Cloud (VPC), VSwitch, Elastic Compute Service (ECS), Cloud Enterprise Network (CEN), Application Load Balancer (ALB).
