WebAssembly - Isolation without Containers

Explore the concept of isolation without containers in this 27-minute conference talk from the inaugural WebAssembly SF Meetup. Delve into topics such as safety, resource isolation, fault detection, isolation, and recovery as presented by Fastly's Tyler McMullen. Examine the fundamentals of processes, virtual memory, and syscalls, and compare them to container technologies. Investigate in-process isolation techniques, including bounds checking and bounds check elision. Gain insights into the potential of WebAssembly for achieving isolation without traditional containerization methods, and witness a live demonstration of these concepts in action.
