Enclaive Managed Databases with Data-in-Use Encryption is a managed database hosting service that encrypts data across all three states: at rest, in transit, and in use (referred to as "3D Encryption"). Unlike conventional managed databases where the service provider can access plaintext data during processing, this service uses hardware-accelerated encryption to ensure data remains concealed from the infrastructure provider at all times. The service supports multiple database engines including MariaDB, MongoDB, PostgreSQL, and Redis. It handles operational tasks such as software updates, patching, and backups, reducing administrative overhead for the customer. Key security properties include: - Continuous encryption during data processing, storage, and transmission - Infrastructure provider cannot access customer data at any point in the lifecycle - Hardware-accelerated encryption to minimize performance impact - Built-in high availability and fault-tolerant architecture to maintain uptime during hardware failures The service is positioned to help organizations meet regulatory compliance requirements including GDPR, HIPAA, and PCI DSS by ensuring sensitive data is encrypted throughout its entire lifecycle. It also simplifies key management by eliminating the need for frequent key rotations or complex cryptographic re-encryption operations.
