In old Japan, anyone crossing a forest or a marsh at night might see small lights floating above the ground: flames, usually bluish, about the size of a candle, appearing in silence, often in groups, drifting apart only to come back together. Today they are explained as gases that ignite spontaneously in damp ground. In the West they are known as will-o’-the-wisps.
This way of working starts from that image: a light that appears where no one looks. In infrastructure, what no one looks at is precisely what ends up failing or growing expensive: the bill nobody reviews, the backups that have never been restored, the permissions nobody audits.
That is why the work combines current methods (infrastructure as code, automated deployments, continuous review) with the Japanese tradition of work done well: one principle that guides everything and four practices that make it possible.
