What each one is
The product in its own terms, so the numbers below have context.
HashiCorp Vault
A system for securely storing and controlling access to secrets like credentials, API keys, and certificates. It generates temporary credentials on-demand, automatically revokes expired secrets, and provides encryption without persistent storage, enabling applications to access secrets through a unified interface with comprehensive audit logging.
Prometheus
A pull-based monitoring platform that periodically scrapes metrics from instrumented targets over HTTP and stores them in a time-series database. It provides PromQL for querying metrics and integrates with Alertmanager for rule-based alerting and incident notifications.
