This operation is suitable for uploading an object smaller than 5 GB in a single request. For objects larger than 5 GB, you must use the multipart upload method.

In a high bandwidth or weak network environment, if your object is relatively large, for example, over 100 MB, we recommend you use Multipart Upload.

Usage Instructions

Use REST APIs to initiate a simple upload request. For more information, see PUT Object.
