Há muitas práticas de SRE neste livro, mas esta é a única que tem o seu próprio capítulo. Aprender com o fracasso é o nexo de uma prática SRE ativa que procura levar-nos ao nível adequado de fiabilidade que desejamos. Para explicar melhor, vamos olhar para as estradas que se encontram nesta encruzilhada.
Em primeiro lugar, tens a monitorização/observabilidade - anteriormente descrita como a coisa mais crucial para se ter solidamente implementada quando se inicia o trabalho de fiabilidade. Esses dados dão-nos clareza sobre o estado atual dos nossos sistemas, o que é.
Em segundo lugar, tens os processos de planeamento do trabalho, como os SLIs/SLOs, que nos permitem especificar com um grau razoável de clareza as nossas intenções e objectivos para o que deve ser.
E, finalmente, tens os incidentes/interrupções (com as práticas de resposta que os acompanham). Estes fornecem (quer queiramos quer não) dados sobre a forma como o que existe pode divergir ou divergiu do que deveria existir.
As práticas em torno da aprendizagem com o fracasso situam-se nesta encruzilhada. Permitem-nos criar e alimentar os ciclos de feedback que nos ajudarão a iterar de onde estamos para onde queremos estar, utilizando a informação que temos sobre como divergimos. Mas isso só acontece se formos intencionais, daí este capítulo.
