Load Balancer的6个实用用例

Load Balancer Realistic Use Cases.

Load balancers are inherently dynamic and adaptable, designed to efficiently address multiple purposes and use cases in network traffic and server workload management.负载均衡器本质上是动态的和适应性强的，旨在有效地解决网络流量和服务器工作负载管理中的多种目的和用例。

Let's explore some of the use cases:

1. Failure Handling(故障处理)

Automatically redirects traffic away from malfunctioning elements to maintain continuous service and reduce service interruptions. 自动将流量重定向远离故障元素，以保持连续服务并减少服务中断。

2. Instance Health Checks(实例健康检查)

Continuously evaluates the functionality of instances, directing incoming requests exclusively to those that are fully operational and efficient. 持续评估实例的功能，将传入请求专门定向到那些完全可操作且高效的实例。

3. Platform Specific Routing(特定平台路由)

Routes requests from different device types (like mobiles, desktops) to specialized backend systems, providing customized responses based on platform. 将来自不同设备类型（如移动设备、PC）的请求路由到专门的后端系统，提供基于平台的定制响应。

4. SSL Termination(HTTPS实现)

Handles the encryption and decryption of SSL traffic, reducing the processing burden on backend infrastructure. 处理 SSL 流量的加密和解密，减轻后端基础设施的处理负担。

5. Cross Zone Load Balancing(跨区域负载均衡)

Distributes incoming traffic across various geographic or network zones, increasing the system's resilience and capacity for handling large volumes of requests. 将传入流量分布到各个地理或网络区域，从而提高系统的弹性和处理大量请求的能力。

6. User Stickiness(用户粘性保持)

Maintains user session integrity and tailored user interactions by consistently directing requests from specific users to designated backend servers. 通过一致地将来自特定用户的请求定向到指定的后端服务器，维护用户会话完整性和定制的用户交互。
