Terms
This topic describes the basic terms for this product.
Region
A region is the physical location of an IVPD service. You can choose a region based on factors such as cost and the source of your requests. A region that is closer to your request source provides faster access. For more information, see available IVPD regions.
Endpoint
An endpoint is the domain name used to access the IVPD service. IVPD provides services through HTTP RESTful APIs. Each region has a unique endpoint. For example, the public endpoint for the China (Shanghai) region is ivpd-cn-shanghai.aliyuncs.com.
AccessKey
An AccessKey pair, which consists of an AccessKeyId and an AccessKeySecret, is used for identity verification. IVPD authenticates a request using symmetric encryption with the AccessKeyId and AccessKeySecret. The AccessKeyId identifies the user. The AccessKeySecret is the key used to encrypt the signature string. IVPD uses this key to verify the signature string. You must keep your AccessKeySecret confidential. You can obtain AccessKey pairs for IVPD from the following sources:
An AccessKey pair that is requested by the owner of the IVPD service.
An AccessKey pair that the IVPD service owner grants to a third-party requester using Resource Access Management (RAM).
An AccessKey pair that the IVPD service owner grants to a third-party requester using Security Token Service (STS).
For more information about AccessKey pairs, see AccessKey.
