The word “isolation” gets used loosely. A Docker container is “isolated.” A microVM is “isolated.” A WebAssembly module is “isolated.” But these are fundamentally different things, with different boundaries, different attack surfaces, and different failure modes. I wanted to write down my learnings on what each layer actually provides, because I think the distinctions matter and allow you to make informed decisions for the problems you are looking to solve.

Debris actually pelts the ISS all the time, and noticeable dents and cracks line the exteriors. But should something fully breach the station, cabin atmosphere will seep into the vacuum of space and alarms will go off. Pressure gauges will confirm to astronauts that the station has, almost certainly, been hit, and the speed of the seepages may indicate how much time the crew has to respond. According to one NASA estimate, a 0.6-centimeter-wide hole leaves 14 hours to plug the leak. A 20-centimeter hole leaves less than a minute.
