Azure 可用性区域

针对任务关键型应用程序和数据的高可用性

使用 Azure 可用性区域确保复原能力和高可用性

将 Azure 可用性区域作为全面的业务连续性和灾难恢复策略的一部分,通过内置的安全性和灵活的高性能体系结构利用高可用性。

提高虚拟机 99.99% 运行时间 SLA 支持的应用复原能力和可用性。

为支持多站点双控 (active-active) 缩放的应用程序启用高级可伸缩性。

满足关键应用程序的合规性和法规要求。

改进恢复时间目标 (RTO) 和恢复点目标 (RPO)。

防范基础结构中断

Eliminate any single point of failure through a regional network design that connects at least three physically distinct strategically placed datacenters in each region, taking into consideration more than 30 viability criteria and risk factors. Maintain synchronous replication, withstand datacenter failures, and ensure customer impact is minimal to none with a latency perimeter of less than two milliseconds between Azure availability zones.

确保高可用性和业务连续性

确保高可用性和业务连续性

在所有可用的 Azure 区域中实现高可用性和业务连续性,而不影响数据驻留。即使主数据中心出现故障,也能访问数据,同时可满足高可用性需求并支持备份。使用区域冗余服务自动实现复原能力。

实现所需的缩放和高可用性

提高缩放能力,确保快速恢复,维护所有应用程序的数据完整性。利用区域冗余服务,从站点故障中无缝恢复,同时降低可用性问题的复杂度。利用自动数据复制功能降低站点恢复的成本,同时利用低延迟数据复制功能实现双控 (active-active) 缩放。

实现所需的缩放和高可用性

安全地满足解决方案要求

借助内置的安全性获得针对可用性区域设计和配置的多区域支持。从包括区域冗余存储 (ZRS) 在内的各种 Azure 服务中进行选择,以便在发生故障时提供整体复原能力。保护可用性区域内和 Azure 区域间的数据传输。

Azure 可用性区域定价

Azure 可用性区域随 Azure 订阅提供。但是,在区域间移动时可能会产生费用。

常见问题解答

  • Azure availability zones are physically and logically separated datacenters with their own independent power source, network, and cooling. Connected with an extremely low-latency network, they become a building block to delivering high availability applications. Availability zones ensure that if there's an event impacting a datacenter site—for example, if someone cuts the power, or there are issues with cooling—your data will be protected. Learn more.
  • Azure 运营区域所在的每个国家/地区都提供可用性区域。了解有关 Azure 地理位置的详细信息。
  • 我们可确保可用性区域之间的延迟时间小于两毫秒,从而将对客户的影响降至最低,甚至没有影响。
  • 可以。区域内或区域间的数据遍历已加密。
  • 在设计过程中,我们利用 30 多项可行性和基于风险的标准来评估每个可用性区域的位置。此过程可识别出显著的个体风险以及可用性区域之间的集体共同风险。
  • Azure services that support availability zones fall into three categories: zonal, zone-redundant, and non-regional services. Customer workloads can be categorized to utilize any of these architecture scenarios to meet application performance and durability.

    • Zonal services: A resource can be deployed to a specific, self-selected availability zone to achieve more stringent latency or performance requirements. Resiliency is self-architected by replicating applications and data to one or more zones within the region. Resources can be pinned to a specific zone. For example, virtual machines, managed disks, or standard IP addresses can be pinned to a specific zone, which allows for increased resilience by having one or more instances of resources spread across zones.
    • Zone-redundant services (ZRS): With zone-redundant services, replication of data is performed automatically to protect resources from single points of failure. Zone redundant storage, for example, replicates the data across three zones so that a zone failure won't impact the high availability of the data.
    • Non-regional services: Services that don’t depend on a specific Azure region, making them resilient to zone-wide outages as well as region-wide outages.

  • 如果应用基于区域冗余服务构建,则无需处理构建应用的复杂性。仅当应用程序同时使用区域级和区域冗余体系结构时,才需要处理复原能力问题。Azure 架构良好的框架是一组可用于提高工作负载质量和详细了解如何构建应用程序的指导原则。
