【云计算】使用Libcloud屏蔽OpenStack、AWS、AliYun等虚拟化层差异

libcloud 是一个访问云计算服务的统一接口，该项目已经成为 Apache 组织的顶级项目，采用 Python 开发。

Apache基金会于5月25日宣布，Libcloud已完成孵化、成为顶级项目。

One Interface To Rule Them All

Python library for interacting with many of the popular cloud service providers using a unified API.

基本示例：

from libcloud.compute.types import Provider
from libcloud.compute.providers import get_driver

import libcloud.security

# This assumes you don't have SSL set up.
# Note: Code like this poses a security risk (MITM attack) and
# that's the reason why you should never use it for anything else
# besides testing. You have been warned.
libcloud.security.VERIFY_SSL_CERT = False

OpenStack = get_driver(Provider.OPENSTACK)
driver = OpenStack('your_auth_username', 'your_auth_password',
                   ex_force_auth_url='http://192.168.1.101:5000',
                   ex_force_auth_version='2.0_password')
