什么是用于 PostgreSQL 的 Azure 数据库？What is Azure Database for PostgreSQL?

Azure Database for PostgreSQL 是 Azure 云中为开发人员构建的关系型数据库服务。Azure Database for PostgreSQL is a relational database service in the Azure cloud built for developers. 它基于开源 PostgreSQL 数据库引擎的社区版本。It is based on the community version of open-source PostgreSQL database engine.

Azure Database for PostgreSQL - 单一服务器Azure Database for PostgreSQL - Single Server

单一服务器部署选项提供：The Single Server deployment option delivers:

  • 没有额外费用的内置高可用性 (99.99% SLA)Built-in high availability with no additional cost (99.99% SLA)
  • 使用非独占预付费定价，实现可预测性能Predictable performance, using inclusive pay-in-advance pricing
  • 根据需要在数秒内垂直缩放Vertical scale as needed within seconds
  • 通过监视和警报功能快速评估缩放的影响Monitoring and alerting to quickly assess the impact of scaling
  • 保护静态和动态敏感数据的安全Secured to protect sensitive data at-rest and in-motion
  • 长达 35 天的自动备份和时间点还原Automatic backups and point-in-time-restore for up to 35 days
  • 企业级安全性和符合性Enterprise-grade security and compliance

所有这些功能几乎都不需要进行任何管理，并且都是在不另外收费的情况下提供的。All those capabilities require almost no administration, and all are provided at no additional cost. 借助这些功能，用户可将注意力集中在如何快速进行应用程序开发、加快推向市场，而不需要花费宝贵的时间和资源来管理虚拟机与基础结构。They allow you to focus on rapid application development and accelerating your time to market, rather than spending precious time and resources to manage virtual machines and infrastructure. 可以使用所选的开源工具和平台继续开发应用程序，不需学习新技能。You can continue to develop your application with the open-source tools and platform of your choice, without having to learn new skills.

“单一服务器”部署选项提供三个定价层：“基本”、“常规用途”和“内存优化”。The Single Server deployment option offers three pricing tiers: Basic, General Purpose, and Memory Optimized. 每个层提供不同的资源功能以支持数据库工作负荷。Each tier offers different resource capabilities to support your database workloads. 可以在一个月内花费很少的费用基于小型数据库构建第一个应用，然后根据解决方案的需求调整缩放。You can build your first app on a small database for a few dollars a month, and then adjust the scale to meet the needs of your solution. 动态可伸缩性使得数据库能够以透明方式对不断变化的资源需求做出响应。Dynamic scalability enables your database to transparently respond to rapidly changing resource requirements. 只需在需要资源时为所需的资源付费。You only pay for the resources you need, and only when you need them. 有关详细信息，请参阅 定价层。See Pricing tiers for details.

数据安全性Data security

Azure Database for PostgreSQL 沿袭了 Azure 数据库服务的数据安全传统。Azure Database for PostgreSQL upholds the Azure database services' tradition of data security. 它的功能可以限制访问、保护静态数据和移动数据，以及帮助你监视活动。It has features that limit access, protect data at-rest and in-motion, and help you monitor activity. 有关 Azure 平台安全性的信息，请访问 Azure 信任中心。Visit the Azure Trust Center for information about Azure's platform security.

Azure Database for PostgreSQL 服务对静态数据使用存储加密，并且符合 FIPS 140-2 标准。The Azure Database for PostgreSQL service uses storage encryption for data at-rest and is FIPS 140-2 compliant. 在磁盘上加密数据（包括备份）。Data, including backups, is encrypted on disk. 该服务使用包含在 Azure 存储加密中的 AES 256 位密码，并且密钥由系统进行管理。The service uses the AES 256-bit cipher included in Azure storage encryption, and the keys are system managed. 存储加密始终处于启用状态，无法禁用。Storage encryption is always on and can't be disabled. 默认情况下，Azure Database for PostgreSQL 服务要求对整个网络的动态数据以及数据库和客户端应用程序之间的动态数据实施安全连接。By default, the Azure Database for PostgreSQL service requires secure connections for data in-motion both across the network and between the database and client application.
