AWS Parameter Store
AWS Parameter Store is a secure, hierarchical storage service for configuration data management and secrets handling, part of AWS Systems Manager. It allows developers to store parameters such as database connection strings, API keys, and configuration values as plain text or encrypted data. It integrates with AWS services like Lambda, EC2, and CloudFormation for dynamic configuration retrieval.
Developers should use AWS Parameter Store when building applications on AWS that require centralized, secure management of configuration and secrets, especially for microservices or serverless architectures. It is ideal for scenarios needing versioning, audit trails, and fine-grained access control via IAM policies, such as in CI/CD pipelines or multi-environment deployments.
