Trade-offThe trade-off versus gVisor is that microVMs have higher per-instance overhead but stronger, hardware-enforced isolation. For CI systems and sandbox platforms where you create thousands of short-lived environments, the boot time and memory overhead add up. For long-lived, high-security workloads, the hardware boundary is worth it.
There are plenty of free versions of popular VPNs, and free trials of VPNs with full access to everything you get with a premium plan. The catch is that free versions usually come with limited data usage, meaning you can't really do any streaming or downloading. Free trials come with everything you get in a paid plan, but they obviously don't last very long. Trials are great for testing out a service before committing, but this isn't a long-term solution.
