How-to guides

The user can enter the required information for Object Storage through the Samsung Cloud Platform Console, select detailed options, and create the service.

Creating an access key

To create and use the Object Storage service in the Samsung Cloud Platform Console, you need to generate an authentication key in advance.

Authentication key creation can be done from My Menu > My Info. > Authentication Key Management > Create Authentication Key. For more details, see IAM > Create Authentication Key.

Reference
  • The authentication key (Access Key, Secret Key) is used when authenticating Amazon S3 utility.
  • The authentication key is used not only for Object Storage, but also for authentication in OpenAPI and CLI.
  • Up to 2 authentication keys can be generated.
Caution
  • If the authentication key expires, access rights to the Object Storage service will be restricted. To ensure smooth service usage, check the authentication key’s expiration period in advance.
  • If you disable the authentication key, access rights to the Object Storage service will be restricted.

Object Storage Create

You can create and use the Object Storage service in the Samsung Cloud Platform Console.

Object Storage Encryption Setup

You can set it to encrypt the data stored in the bucket. After setting bucket encryption, the encryption setting is applied to uploaded data. When using encryption, the SSE‑S3 encryption key method and the AES256 encryption algorithm are applied.

Reference
Object Storage bucket encryption can provide two types (SSE‑S3/SSE‑KMS). SSE‑S3 is server‑side encryption (SSE‑S3) using Amazon S3 managed keys. SSE‑KMS is server‑side encryption (SSE‑KMS) using Key Management Service (KMS) keys.
In this service, server‑side encryption (SSE‑S3) using Amazon S3 managed keys is released as the default method, and server‑side encryption (SSE‑KMS) using Key Management Service (KMS) keys will be provided later according to the service roadmap.

Information

If there is data saved before bucket encryption was set, the encryption settings will not be applied.

  • If you re-upload the file, encryption will be applied.
