In view of the difficulty of real-time data synchronization between different databases, Ali Cloud recently announced the launch of hybrid cloud data synchronization one-stop solution, which is convenient for the majority of cloud product users to achieve real-time data synchronization hybrid cloud support. More conveniently, this function enables the local Oracle to achieve real-time synchronization with the database on the cloud.
At present, many users have real-time data synchronization requirements between Oracle, MySQL and ali Cloud RDS or ECS self-built databases from cloud or other vendors. The DTS hybrid cloud data synchronization function applies to multiple user application scenarios, including:
1. Business gray scale switching
If the service system is complex, you cannot switch to the Ari Cloud at one time. In this case, services can be switched to the cloud by service module, region, or user. DTS is used to synchronize data between the cloud and the cloud or between cloud vendors. When traffic switchover is abnormal, services can be quickly rolled back to effectively control service migration risks.
2. Data Dr
Even the most reliable service provider, is also likely to encounter bad luck one day, to ensure business continuity, the business can be mixed by DTS cloud syncing, on ali cloud fleetly local business center or other cloud vendor’s business center corresponding data disaster preparedness, when the failure of the business center, rapid disaster will switch to the business center, second grade recovery operations.
3. Service elasticity expansion
Due to the flexibility, scalability and low cost of the cloud, aliyun can flexibly expand and support part of the business traffic in case of sudden traffic promotion. In this case, services can use DTS hybrid cloud synchronization to synchronize data on and off the cloud, ensuring localized service access and effectively improving user experience.
Ali Yunyun BI
Ali Cloud provides a set of low-cost and highly reliable big data products. Users can synchronize business updates of offline databases to Ali Cloud big data products in real time through the DTS hybrid cloud synchronization function, and build their own big data applications and platforms quickly and at a low cost based on Ali Cloud big data products.
For databases under the cloud or cloud vendors, the solution released by Ali Cloud can support data transmission through dedicated lines, giving consideration to transmission performance and data security. Including: Real-time data synchronization between Oracle and MySQL or DRDS. Real-time data synchronization between Oracle and OLAP (MaxCompute, AnalyticDB). Single-directional data synchronization between MySQL instances. Real-time data synchronization between MySQL and OLAP (MaxCompute, AnalyticDB, and Datahub).
The data synchronization architecture diagram is as follows:
It is understood that at present this function is in a leading position in China, and Oracle data synchronization, and two-way data synchronization function, currently only Alibaba cloud data transmission service DTS support.
It is also very convenient to use, only three steps:
- Log in to the data transfer service DTS purchase page to purchase a data synchronization instance
- Enter the DTS console, configure the connection mode of the source instance and target instance to be synchronized, and select the library or table to be synchronized
- After the configuration is complete, the DTS automatically starts the synchronization instance after the pre-check is successful.
