In this lesson, you have learned:
在本课中，您已学到：

• Deployment models indicate where the infrastructure resides, who owns and manages it, and how cloud resources and services are made available to users. There are four main deployment models available on the cloud—public, private, hybrid, and community.
  部署模型表明基础设施的存放位置、所有权和管理者，以及云资源和服务的可用方式。云上提供四种主要的部署模型——公有云、私有云、混合云和社区云。
• In the public cloud model, the service provider owns, manages, provisions, and maintains the physical infrastructure such as data centers, servers, networking equipment, and storage, with users accessing virtualized computing, networking and storage resources as services.
  在公有云模型中，服务提供商拥有、管理、配置和维护物理基础设施，如数据中心、服务器、网络设备和存储设备，用户以服务的形式访问虚拟化的计算、网络和存储资源。
• In the private cloud model, the provider provisions the cloud infrastructure for exclusive use by a single organization. The private cloud infrastructure can be internal to the organization and run or on-premises. Or it can be on a public cloud, as in the case of Virtual Private Clouds (VPC), and be owned, managed, and operated by the cloud provider.
  在私有云模型中，提供商为单个组织提供云基础设施，仅供该组织专用。私有云基础设施可以是组织内部的，并在本地运行。或者它可以在公共云上，例如在虚拟专用云（VPC）的情况下，由云提供商拥有、管理和运营。
• In the hybrid cloud model, an organization’s on-premise private cloud and a third-party, public cloud are connected as a single, flexible infrastructure that leverages the features and benefits of both Public and Private clouds.
  在混合云模型中，组织的本地私有云和第三方公有云连接成一个单一、灵活的基础设施，该基础设施利用了公有云和私有云的特点和优势。
• In the community cloud model, the provider provisions the cloud infrastructure for use by a community of organizations with shared concerns. One or more of the organizations in the community, a third-party provider, or both are responsible for the ownership, management, and operation of this infrastructure.
  在社区云模型中，提供商为具有共同关注点的组织群体提供云基础设施供其使用。社区中的一个或多个组织、第三方提供商或两者共同负责该基础设施的所有权、管理和运营。
