This topic describes the Alibaba Cloud services that can be integrated with Key Management Service (KMS).
If you purchased an Alibaba Cloud service that can be integrated with KMS and your business requirements can be met by using default keys, you do not need to purchase a KMS instance. A default key can be of the following types: service key and customer master key (CMK).
Workload data encryption
Service | Description | References |
Elastic Compute Service (ECS) | By default, the disk encryption feature of ECS uses service keys to encrypt data. This feature can also use user-created keys to encrypt data. To encrypt data stored on each disk, you must use a key and a data key that are specific to the disk and use the envelope encryption mechanism. The disk encryption feature encrypts the data that is transmitted from an ECS instance to a disk and decrypts the data that is read from the disk. Data encryption and decryption is performed on the host on which the ECS instance resides. During encryption and decryption, the performance of the disk is not affected. After an encrypted disk is created and attached to an ECS instance, the ECS instance encrypts the following data:

Container Service for Kubernetes (ACK) | ACK supports server-side encryption (SSE) based on KMS for the following types of workload data:
|
Persistent storage encryption
Service | Description | References |
Object Storage Service (OSS) | OSS uses the SSE feature to encrypt uploaded data.
OSS can use an encryption system that is dedicated to OSS to implement the SSE feature. This encryption method is referred to as SSE-OSS. The keys used in this encryption system are not managed by OSS. Therefore, you cannot use ActionTrail to audit the use of these keys. OSS can also use KMS to implement the SSE feature. This encryption method is referred to as SSE-KMS. This method allows OSS to use service keys or user-managed keys to encrypt data. You can configure a service key for each bucket or specify a key when you upload an object. | |
Apsara File Storage NAS | By default, NAS uses a service key to encrypt data. To encrypt data stored on each volume, you must use a key and a data key that are specific to the volume and use the envelope encryption mechanism. | |
Tablestore | By default, Tablestore uses a service key to encrypt data. Tablestore can also use user-managed keys to encrypt your data. To encrypt data stored on each table, you must use a key and a data key that are specific to the table and use the envelope encryption mechanism. | None |
Cloud Storage Gateway (CSG) | CSG supports the following encryption methods:
| |
Microservices Engine (MSE) | Configuration data in Microservices Registry of Microservices Engine (MSE) is stored in plaintext. MSE is integrated with Key Management Service (KMS) to allow you to encrypt and decrypt configuration data, such as data sources, tokens, usernames, and passwords. This helps reduce the risk of sensitive data leaks. |
Database encryption

ApsaraDB RDS | ApsaraDB RDS supports the following encryption methods:
|
|
ApsaraDB for MongoDB | The TDE feature is provided. The encryption methods for ApsaraDB for MongoDB are similar to those for ApsaraDB RDS. | |
PolarDB |
| |
ApsaraDB for OceanBase | ||
ApsaraDB for Redis |
Log data encryption
Service | Description | References |
ActionTrail | When you create a single-account or multi-account trail, you can enable encryption for events that are delivered to OSS in the ActionTrail console. | |
Simple Log Service (SLS) | Simple Log Service can be integrated with KMS to encrypt data for secure storage. Static data protection is provided. |
Big data and AI
Service | Description | References |
MaxCompute | MaxCompute can use service keys or user-managed keys to encrypt your data. | |
Platform for AI | You can configure SSE for the cloud services that are used in the architecture of PAI and different data flow stages, such as computing engines, ACK, and data storage services. This protects data security and privacy. | None |
Other scenarios

Alibaba Cloud CDN (CDN) | When an OSS bucket is used as the origin server, you can use OSS-based SSE to protect distributed content. | Grant Alibaba Cloud CDN access permissions on private OSS buckets |
ApsaraVideo Media Processing (MPS) | MPS supports two encryption methods: Alibaba Cloud proprietary cryptography and HTTP Live Streaming (HLS) encryption. You can integrate MPS with KMS to protect video content regardless of the encryption method used. | None |
ApsaraVideo VOD | VOD supports two encryption methods: Alibaba Cloud proprietary cryptography and HLS encryption. You can integrate VOD with KMS to protect video content regardless of the encryption method used. |
