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 secrets (with optional KMS encryption). Azure App Configuration focuses on app settings and feature flags (secrets typically go in Azure Key Vault). GCP Secret Manager and OCI Vault primarily manage secrets; for non-secret configuration, teams often pair them with separate config services.
