AWS AppConfig, a capability of AWS Systems Manager, is specifically designed to manage feature flags, configuration changes, and application toggles safely and dynamically. AWS documentation highlights AppConfig as the recommended service for enabling and disabling application features without redeploying code.
Feature flags in AppConfig allow developers to control visibility, rollout strategies, and gradual releases across environments. AppConfig supports validation, monitoring, and rollback to prevent misconfigurations from impacting users.
Option A is incorrect because AWS AppSync is a GraphQL service and does not manage feature flags. Options B and D misuse data storage and synchronization services for configuration management, introducing unnecessary complexity and risk.
Using AWS AppConfig enables developers to hide features, activate them instantly when ready, and manage them centrally with minimal operational overhead.
Therefore, AWS AppConfig feature flags are the correct and AWS-recommended solution.
