Verified容器技术（以Docker为代表）利用Linux内核的namespace机制实现进程、网络、文件系统隔离，借助cgroups限制CPU、内存等资源用量79% similarUnverifiedContainerization technology leverages the namespace and cgroup features of the Linux kernel to build isolated runtime environments without relying on full virtual machines.77% similarVerifiedThe essential difference between container technology and virtual machines is that containers share the host machine's operating system kernel and achieve isolation and resource limiting through Linux's Namespace and Cgroup mechanisms.77% similarUnverifiedA persistent Linux virtual machine retains a complete file system, running processes, historical operation records, and installed packages, unlike ordinary sandbox environments that clear state after each conversation.75% similarUnverifiedSandbox technology uses operating-system-level isolation mechanisms (such as Linux's seccomp, namespaces, cgroups, or dedicated virtual machines) to restrict process system-call permissions, but its granularity is binary and it is difficult to express business-level policies.74% similar
