Use Multipart Upload to upload parts of a file in parallel to speed up the upload process

Multipart Upload is usually used when the size of the file to be uploaded is large

If the upload fails due to an accident during the uploading of fragments, you need to upload all the fragments again

After an upload is interrupted, the portions of the file which have successfully uploaded prior to the interruption will be saved in the OSS bucket

RAM users can be created under a single Alibaba Cloud account, corresponding to employees, systems, or applications.

RAM users do not "own" the resources that they create (those belong to the Alibaba Cloud account itself), and RAM users cannot generate and pay their own individual bills (costs accrue to and are billed to the master Alibaba Cloud account).

RAM users belong to an Alibaba Cloud account, but they can also operate as independent accounts with their own private resources, not visible to the primary Alibaba Cloud account.

RAM users must be authorized by the Alibaba Cloud account to log in to the console or use the API to manage the resources owned by the Alibaba Cloud account.

A snapshot is a backup file of the cloud disk data state at a certain point in time. The first snapshot of the cloud disk is a full snapshot of the ac usage. Empty data blocks are not backed up. All subsequent snapshots are incremental snapshots, and only changed data blocks are stored.

Snapshots can be created manually through the web console or command line tools, or automatically according to a schedule.

In the event of a system failure, you can use a snapshot to roll back the Cloud Disk to an earlier point in time.

Snapshot rollbacks can be performed while the ECS instance is running.

RDS realizes real-time synchronization between the master instance and the remote disaster recovery instance through Data Transmission Service (DTS)

When an outage occurs in the area where the primary instance is located, and neither the primary instance (Master) nor the standby instance (Slave) can be connected to, the remote disaster recovery instance can be switched to the primary instance

When the database deletion operation is performed on the master instance, the operation will also be synchronized to the disaster recovery instance

Alibaba Cloud provides a wealth of block storage products for ECS, including Cloud Disks (virtualized storage) and Local Disks (physically attached to the server(s) that host your ECS Instances).

Both Local Disks and Cloud Disks use a multi-copy distributed storage mechanism, which has low latency, high performance, durability, and high reliability, and supports creation, expansion and release at any time.

Cloud Disks come In several different varieties: ESSD (Enhanced Solid State) Cloud Disks. SSD (Solid State ) Cloud Disks, and high-efficiency Cloud Disks.

Two types of Cloud Disks can be attached to an ECS: System Disks and Data Disks. System Disks host the ECS instances operating system.
