OpenStack:
IaaS Cloud Stack, Cloudos
Private Cloud (built-in for company use)
Public Cloud (leased cloud provider)
Hybrid cloud (rental and self-built)

    IaaS（OpenStack，CloudStack，PaaS（Docker，Openshift），SaaS）    DBaaS（数据库及服务），FWaaS（防火墙及服务）    IaaS按需提供VM

OpenStack Components:
Dashboard:horizon,webgui;
Compute:nova, manage the entire life cycle of VMS, the main responsibility is to create, schedule and launch virtual machine instances;
Networking:neutron, earlier called Quantum, before independence for Nova-networking, to start network connectivity and services, to provide users with on-demand network connectivity API, plug-in design, support more network services Provider Network framework, Support Openvswitch;
Object Storage:swift, which provides storage and retrieval of unstructured data objects through restful interfaces, is a highly tolerant data replication and scaling architecture, distributed storage;
Block Storage:cinder, early risers are provided by Nova, code for Nova-storate, providing a persistent block storage capability for virtual machines;
Identify Service:keystone for all OpenStack services and access to end-of-service services;
Image service:glance for storing and retrieving disk image files;
Telemetry:cilometer for the realization of monitoring and metering services;
Orchestration:heat, for multi-component linkage
Database Service:trove, to provide DBAAS service implementation;
Data processing Service:sahara for the management of Hadoop in OpenStack;
