I don't work at a giant company, but I'm curious: > Anyone that has worked on large, complex system knows that the margin of error in uptime and downtime is often whether the right person is within arms’ reach of their laptop. Is this true? Shouldn't giant tech companies obsess about reducing the need for human intervention?
The companies where it was not true, was a pleasure to work in. The management, from C-suits downwards knew what they were doing. In the others, it was a total chaos.
Of course, if everything is fixed with duct tape, you need firemen ready to act. If everything is solid and robust, there can be small outages, but nothing too critical.
