Simon Willison argues that default hard budget caps should be applied to nearly all cloud and infrastructure spending to prevent runaway costs. The article suggests that without strict limits, engineering teams often exceed budgets due to lack of immediate visibility or friction in stopping resource consumption. This approach aims to enforce financial discipline by design rather than relying on voluntary adherence.
- Shift from soft limits to hard caps by default to enforce spending discipline
- Reduce friction in stopping resource consumption to prevent runaway costs
- Design infrastructure controls that prioritize financial safety over convenience
- Encourage teams to monitor usage closely when hard limits are in place
