Availability Zone
A concept in cloud data center architecture referring to a cluster of facilities within the same region that are physically isolated and have independent power and cooling systems, used to achieve highly available deployments.
Timeline (last 90 days)
Milan adds two new availability zones, bringing the region to three availability zones, and the resulting service is officially called enterprise-grade resilience.
The industry generally regards three availability zones as the baseline for production-grade deployment: when an application is redundantly deployed across three availability zones, it can both fail over automatically on a single point of failure and maintain acceptable replication latency across the zones.
In mainstream cloud platform architectures, a "region" refers to a geographically independent major area, and each region is divided internally into several "availability zones," which are usually physical data center clusters tens of kilometers apart with independent power and cooling systems.
一个云服务区域通常包含多个地理上相互隔离的可用区，彼此通过低延迟专线连接
跨多个可用区部署应用可在单一数据中心故障时自动切换，满足高可用性要求
When data is written to the S3 Standard storage class, the system automatically replicates the data redundantly across multiple devices in at least three availability zones within the same region and continuously performs checksum verification.
