Probability 策略的基本原理

标题：深入解析 Kubernetes Service 负载均衡策略之 Probability

在 Kubernetes 中，Service 是一种抽象概念，用于提供对一组 Pod 的稳定网络访问，而负载均衡策略则决定了如何将流量分配到这些 Pod 上，Probability（概率）策略是一种较为灵活的负载均衡方式，它允许为每个后端 Pod 分配一个概率权重，从而实现基于概率的请求分发。

Probability 策略的基本原理

Probability 策略的核心思想是根据每个 Pod 被选中的概率来分配流量，Kubernetes 会根据每个 Pod 的权重计算出其被选中的概率，然后通过随机数生成器来决定将请求分发到哪个 Pod 上，概率权重的计算方式如下：
