gVisor intercepts container syscalls through a user-space kernel called runsc, delivering strong isolation with surprisingly low overhead. This post examines its architecture, syscall interception strategy, and real-world production tradeoffs.
gVisor reimagines container isolation by implementing a minimal Linux kernel in userspace, intercepting syscalls to create a secure sandbox without sacrificing performance.
How to choose gVisor for isolation-heavy container workloads, covering architecture, production patterns, and practical migration steps.
How gVisor reimplements the Linux kernel in user space to safely sandbox containers, and what the trade-offs look like in real deployments.
gVisor moves the Linux kernel into userspace to sandbox containers at the syscall boundary, trading raw throughput for a dramatically smaller attack surface.
