## Introduction
2+
<!-- DOCS_DESCRIPTION_CN -->
3+
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。

7+
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).
