Tencent Distributed Cloud uses public cloud technology and products. Compared with traditional private cloud products, it has great advantages in upgrading.
Although traditional private cloud products, although a highly available architecture provides high -available architecture, can support online upgrades. However, due to the operation and maintenance management capabilities of customers, it is often impossible to upgrade with the versions of the cloud products. After iterates in private cloud products, the risk of cross -generation upgrades has increased. Therefore, the private cloud rarely upgrades after construction, which will also lead to the security vulnerabilities in private cloud products. It is easy to exist in the customer environment for a long time, which will cause customers to use the private cloud time and the higher the risk of security.
Tencent Distributed Cloud uses public cloud technology and products. When designing and implementing product design and implementation, the online upgrade ability and compatibility with the old versions are considered. The software update and deployment of CDC/CDZ are exactly the same as the public cloud scheme. By the dedicated line or VPN that is opened with the region, the upgrade package can be automatically pushed to the local area and automated the upgrade. Like the public cloud, based on the strategies such as full links, full components, and blue -green upgrades, the upgrade process is performed online, which will not cause any interruption of customer workloads. Because the TENCENT Distributed Cloud will upgrade with the public cloud synchronous versions, the transmissions upgrades rarely occur, the upgrade risk is acceptable, and there is a comprehensive plan to reduce the risk of upgrade, and it can quickly solve or return when problems occur. Therefore, the components used in the Tencent Distributed Cloud product, even if there is a safe loophole, will be quickly repaired with the iteration of the product version, and the safety is high.
