Tencent distributed cloud uses public cloud technology and products. Compared to traditional private cloud products, it has significant advantages in upgrades.

Although traditional private cloud products provide high availability architecture and support online upgrades, customers' Ops and management capabilities often prevent them from synchronizing with cloud product versions. After private cloud products iteration, the risk of cross-generation upgrades increases. As a result, upgrades are rare after a private cloud is built, leading to security vulnerabilities in private cloud products. These vulnerabilities can exist long-term in customer environments, causing the longer customers use the private cloud, the higher security risks will be.

Tencent distributed cloud adopts public cloud technologies and products. During product design and implementation, online upgrade capability and compatibility with older versions are considered. The software updates and deployment of Cloud Dedicated Cluster (CDC)/Cloud Dedicated Zone (CDZ) are identical to those in public cloud solutions. Through direct connect or VPNs activated regionally, upgrade packages can be automatically pushed locally and upgraded automatically. Like the public cloud, based on full linkage, full components, and blue-green upgrade policies, the upgrade process is carried out online without causing any interruptions to customer workloads. Since Tencent distributed cloud upgrades in sync with the public cloud version, transfer upgrades are rare. The upgrade risk is acceptable, and comprehensive plans are in place to mitigate upgrade risks. In case of issues, they can be quickly resolved or rolled back. Therefore, the components used in Tencent distributed cloud products, even if they have security vulnerabilities, will be quickly patched with product version iterations, which ensures high security.
