Recently, Ali cloud officially released OSS city of redundant storage products. This is currently the subject of cloud storage products available on the city multi-AZ deployment capabilities covering the most extensive redundancy, you can achieve double-live city cloud storage, enterprise-class customers for the "event of a disaster during the engineering level data is not lost, services are not interrupted "requirements. Relative to the user self-built city disaster recovery room, OSS city redundant storage, can greatly reduce the construction costs. At the same time, with the current OSS "cross zone transfer" capability, you can easily build cloud storage "three centers in two" architecture. At this point, Ali cloud OSS can provide different services with the engine room, city, cross-regional full service multi-level disaster recovery capabilities.
Due to limited IT capabilities, costs and other factors, a considerable number of enterprise customers critical business data does not have the same city disaster recovery capabilities. Off the network data center room, power outages, equipment damage and other events may cause business disruption, and even loss of data. Therefore, how to help business-critical system data to build a more secure, reliable, flexible disaster recovery system, has become a domestic enterprise-class customers a very urgent need.
Today, Ali cloud released OSS "city redundant storage" products. It is possible to upload user data stored in the same local dispersion (Region) of three different available areas. Even in the face when one of the available area in extreme cases the overall destruction still be able to ensure that users of business data can be used normally, ensure business continuity.
The release of the OSS "city redundant storage" products, has the following three characteristics:
- Room-level disaster recovery capability provides: OSS "city redundancy memory" products provide 99.9999999999 percent (12 9) of the data reliability. When the service terminal or catastrophic event resulting in a room is not available, is still able to ensure continued strong consistency of service capabilities, the entire failover process without user awareness, services are not interrupted, data is not lost. For mission critical systems meet RPO = 0, RTO = 0 ultimate requirements.
- Higher availability SLA indicators: OSS "city redundant storage" provides 99.95% availability SLA indicators, compared to the current standard storage type single AZ, SLA availability index 2 times increase.
- A key to open: based on OSS "city redundant storage", the city can build a cloud disaster recovery service capabilities easily. Users only need when creating Bucket, open the "city area redundant" storage attribute. OSS multi-copy user data is automatically stored in dispersed dozens of kilometers away from the city's three different available areas.
Currently OSS "city area stores" has been published on line in Beijing, Shanghai, Shenzhen local Chinese stations, the recent Hangzhou, Singapore is also planning to publish on-line.
Ali cloud OSS again changed the construction mode cloud storage disaster recovery system and user habits. Pratt & Whitney ability by means of the cloud, so that more businesses to build on the "elasticity, stability, security," the city disaster recovery cloud-based business systems Ali cloud OSS.
