AWS service for securely storing and managing configuration data and secrets. Like a secure vault specifically designed for application settings and passwords.
Applications retrieve database connection strings from Parameter Store instead of hardcoding them in source code.
AWS Systems Manager Parameter Store stores configuration values and (optionally) encrypted secrets. Azure App Configuration focuses on app settings and feature flags (secrets typically go in Key Vault). GCP Secret Manager and OCI Vault are primarily for secrets; for non-secret configuration, GCP commonly uses runtime config patterns (e.g., environment variables, config files, or service-specific config) alongside Secret Manager.
