SLOs, error budgets and the engineering of trust.
How we translate uptime commitments into release cadence, on-call structure and architectural pressure — without pretending reliability is free.
Reliability is not a promise, it's a budget. Every nine you add costs an order of magnitude more effort than the last one. Pretending otherwise is how teams end up over-investing in the wrong parts of the system.
From SLO to release cadence
An SLO is a decision about how much risk the business is willing to accept. Once written down, it drives everything else: how often you can ship, how much automation you need, how the on-call rotation is shaped, and where the architecture must be hardened first.
Error budgets as a conversation
Error budgets are how engineering and the business have honest conversations about tradeoffs. Burn the budget on a bad release, and the next sprint is reliability work — no debate required. That's not bureaucracy, it's an operating agreement.
