01Delivery metrics
DORA’s research measures software delivery with four keys: deployment frequency, lead time for changes, change failure rate and time to restore service [1].
02Monitoring and backups
Google’s SRE guidance centres monitoring on four golden signals: latency, traffic, errors and saturation [2]. Its data-integrity chapter stresses that backups only count once restores are tested [3].
03Config and TLS
Configuration lives in the environment, following the Twelve-Factor App [5], and TLS settings follow Mozilla’s recommended configurations [4].
