autoscaling/v1只支持针对 CPU 指标的扩缩容; autoscaling/V2beta1除了 cpu,新引入内存利用率指标来扩缩容; autoscaling/V2beta2除了 cpu 和内存利用率,新引入了自定义和外部指标来扩缩容,支持同时指定多个指标; v2 版本相较 v1 做了不少扩展,除了增加自义定和外部指标外,还支持多指标,当定义多个指标时,HPA ...
k8s 平台采用了“核心+外围扩展”的设计思路,在保持平台核心稳定的同时,具备持续演进升级的优势。k8s 大部分常见的核心资源对象都归属 v1 这个 core(核心)API,比如Node、Pod、Service、Endpoints、Namespace、RC、PersistentVolume等。在版本迭代过程中,k8s 先后扩展了extensions/v1beta1、apps/v1beta1、apps/v1beta...
然后上游服务器进行响应后再返回数据给客户端。负载均衡的最常见应用是充当反向代理，通过负载均衡，可以大大的提高服务的响应速度、提高并发请求、提高稳定性（防止单点故障）。 负载均衡的基本实现方案，从业界来看，一般分为软件和硬件两大类，软件负载均衡又可以分层如4层、7层负载均衡，如下：
