简单的轮询负载平衡
以轮询的形式将请求依次发送到不同的服务器，即每次调度执行i=（i+1）mod n
如果需要源代码，可以添加企鹅球：21477756333
随机负载平衡
随机选择UP状态的服务器
加权响应时间负载平衡
根据响应时间分配权重。响应时间越长，权重越小，被选中的概率越低。
区域感知负载平衡
区域感知负载平衡的内置电路跳闸逻辑可以配置为基于区域同源性（区域亲和力，即更倾向于发送呼叫的服务所在的托管区域，这可以减少延迟并节省成本）来选择目标服务实例。它监视每个区域中运行实例的行为，并可以实时快速丢弃整个区域。这有助于我们在面对整个地区的失败时提高灵活性。

从现在起，我将记录最近开发的spring云微服务云架构的构建过程和本质，以帮助更多对开发spring云框架感兴趣的朋友。让我们讨论一下spring云架构的构建过程，以及如何将其应用于企业项目。
