Background
A single mobile tap can trigger a number of events behind the scenes — API calls to microservices, messages/events sent through queues, writes to databases, and retries on transient failures — all before it returns with a success… or an error toast. The user doesn’t see this complexity. They don’t know about your autoscaling policy, cache hit ratios, or dependency graphs. They only know whether their ride was hailed, their payment went through, or their food order was confirmed.
And when things go wrong, it’s that hidden complexity that determines how gracefully your system recovers. That’s why reliability can’t just be the SRE team’s job anymore. It’s a shared responsibility — one that should be embedded in the day-to-day decisions of every back-end engineer. From the way we design systems to how we write alerts, ship code, and handle incidents, reliability is engineered — not wished into existence.
