1: What is openstack

OpenStack is an open source cloud computing management platform project and a combination of a series of software open source projects. It is an open source code project developed and initiated by NASA (National Aeronautics and Space Administration) and Rackspace, and licensed under the Apache License (a free software license issued by the Apache Software Foundation).

OpenStack provides scalable and elastic cloud computing services for private clouds and public clouds. The project goal is to provide a cloud computing management platform that is easy to implement, massively scalable, rich, and has unified standards.

2: The main functional components of openstack

are mainly divided into 5 different levels and 16 different functional modules:

Presentation [Presentation layer] : api module, ui module

Logic (Control) [Logic Control Layer]: Orchestration [Orchestration Service], Scheduling [Scheduling Service], Policy [Policy Service], Image Registry [Image Registration Service], Logging [ Log Service]

Resource [Resource Management]: Compute [Computing Resource Management Module], Volume [Storage Resource Management Module], Network [Network Resource Management Module]

Integration [Integration Layer] ：Billing【Metering module】, Identity【Identity authentication module】

Mabagement【Management】: Admin【Management api】, Monitoring【Monitoring】

How the sub-projects are connected:

Horizon-UI Service: Corresponds to User Dashboard [off-cloud service for operation and maintenance users] and Customer Portal [for cloud users]

Keystone-Identity Authentication: Corresponds to Identity
