Has gvisor ever been popped? Has there ever even been a single high-profile compromise caused by a container escape? Shared hosting was a thing and considered &amp;quot;safe enough&amp;quot; for decades and that&amp;#x27;s all process isolation.&lt;p&gt;Can&amp;#x27;t help but feel the security concerns are overblown. To support my claim; Well, Google IS using gvisor as part of their GKE sandboxing security..</text><parent_chain><item><author>eddythompson80</author><text>Google is moving away from gvisor as well.&lt;p&gt;The &amp;quot;process sandbox&amp;quot; wars are over. Everybody lost, hypervisors won. That&amp;#x27;s it. It feels incredibly wasteful after all. Hypervisors don&amp;#x27;t share mm, scheduler, etc. It&amp;#x27;s a lot of wasted resources. Google came in with gvisor at the last minute to try to say &amp;quot;no, sandboxes aren&amp;#x27;t dead. Look at our approach with gvisor&amp;quot;. They lost too and are now moving away from it.</text></item><item><author>monocasa</author><text>Does google?
