Which Cloud Services Can Use KMS for Encryption?
Object Storage Service (OBS), Elastic Volume Service (EVS), Image Management Service (IMS), and Relational Database Service (RDS) can use KMS for encryption.
Service Name |
Description |
---|---|
Object Storage Service (OBS) |
You can upload objects to and download them from Object Storage Service (OBS) in common mode or server-side encryption mode. When you upload objects in encryption mode, data is encrypted at the server side and then securely stored on OBS in ciphertext. When you download encrypted objects, the data in ciphertext is decrypted at the server side and then provided to you in plaintext. OBS supports the server-side encryption with KMS-managed keys (SSE-KMS) mode. In SSE-KMS mode, OBS uses the keys provided by KMS for server-side encryption. For details about how to upload objects to OBS in SSE-KMS mode, see the Object Storage Service Console Operation Guide. |
Elastic Volume Service (EVS) |
If you enable the encryption function when creating an EVS disk, the disk will be encrypted with the DEK generated by using your CMK. Data stored in the EVS disk will be automatically encrypted. For details about how to use the encryption function of EVS, see Elastic Volume Service User Guide. |
Image Management Service (IMS) |
When creating a private image using an external image file, you can enable the private image encryption function and select a CMK provided by KMS to encrypt the image. For details about how to use the private image encryption function of Image Management Service (IMS), see Image Management Service User Guide. |
Scalable File Service (SFS) |
When creating a file system on SFS, the CMK provided by KMS can be selected to encrypt the file system, so that files stored in the file system are automatically encrypted. For details about how to use the file system encryption function of SFS, see Scalable File Service User Guide. |
Relational Database Service (RDS) |
When purchasing a database instance, you can enable the disk encryption function of the database instance and select a CMK created on KMS to encrypt the disk of the database instance. Enabling the disk encryption function will enhance data security. For details about how to use the disk encryption function of RDS, see Relational Database Service User Guide. |
Document Database Service (DDS) |
When purchasing a DDS instance, you can enable the disk encryption function of the instance and select a CMK created on KMS to encrypt the disk of the instance. Enabling the disk encryption function will enhance data security. For details about how to use the disk encryption function of DDS, see Document Database Service Getting Started. |
