Compared to Community Editions of OS Such As Rocky Linux and AlmaLinux, What are the Advantages of TencentOS Server?
As an enterprise-level OS, TencentOS Server surpasses Community Editions of OS in terms of maintenance lifecycle, stability, security, performance, and the integration or support for cloud-native features and virtualization technology.
Currently, TencentOS Server 2 and 3 editions are independently evolved based on the upstream LTS 5.4 version, whereas the mainstream Community Editions of OS on the market are mostly based on 3.x or 4.x version kernels. Compared to these version kernels, the 5.x series has made further improvements and enhancements in areas such as SELinux, Kernel Security Reinforcement, Efficient Memory Management, Scheduler/File System/Network Stack Optimization, and improvement of KVM/Xen Virtualization Platform. These improvements are particularly important for the high availability, data security, performance, and efficiency of cloud computing services.
Community OS is not as stable as RHEL or traditional CentOS versions that have undergone long-term testing and certification, therefore, it is not suitable for production environment applications and users with high requirements for long-term stable operation and compatibility of OS.
