VMware Vcenter_API

介绍

本文主要通过调用Vcenter_API,获取其中的数据中心,集群,主机,网络,存储,虚拟机信息。

安装:

pip install pyvmomi
pip install pyVim

自己总结的调用API:

Twitter的分布式自增ID算法snowflake (Java版)
概述分布式系统中,有一些需要使用全局唯一ID的场景,这种时候为了防止ID冲突可以使用36位的UUID,但是UUID有一些缺点,首先他相对比较长,另外UUID一般是无序的。有些时候我们希望能使用一种简单一些的ID,并且希望ID能够按照时间有序生成。而twitter的snowflake解决了这种需求,最初Twitter把存储系统从MySQL迁移
