Openstack平台的构建与实施

任何技术的产生,都离不开人类生产的实际需求。IT信息发展的第一阶段实现将分散的各类IT资源进行物理集中,形成具有一定规模IT基础设施建设。第二阶段,随着企业IT基础设施需要扩充,需要进行硬件设备的升级、安装以及应用软件的部署运维等过程,此过程建设周期长,而且经济成本高,资源重复利用率低。到达第三阶段时,企业的IT系统历经一段时间后,基础硬件面临老化,系统软件面临升级等。

The production of any technology is inseparable from the actual needs of human production. The first phase of IT information development will realize the physical concentration of various types of IT resources and form a certain scale of IT infrastructure construction. In the second phase, as the enterprise IT infrastructure needs to be expanded, the hardware equipment upgrade, installation, and application software deployment and operation and maintenance processes are required. This process has a long construction period, high economic cost, and low resource reuse. When the third stage is reached, the enterprise's IT system will face aging after a period of time, and the system software will face an upgrade.
