About the workshop
Matt runs the room through deliberately broken sandboxes, capture-the-flag style. Each fix unlocks the next level, and each challenge runs in its own sandbox, so a mistake resets without breaking anyone else's.
The second half goes from one sandbox to thousands: how long a sandbox should live, how to send each user back to the same workspace, and what a restored snapshot brings back with it. The Q&A covers volumes, storage growth, orchestration and network limits.
