Description
Individual Edition
TCR Individual Edition provides basic cloud image hosting and distribution services with quota limits. It is designed for personal use or temporary testing by enterprise customers. The services offered by the Individual Edition are shared cloud services, that is, all Individual Edition users share the service backend and data storage, with quota limits on image hosting and upload/download. The TCR Individual Edition is free of charge and can be activated directly. For use of the edition, see Getting Started with TCR Individual Edition.
Enterprise Edition (Basic)
TCR Enterprise Edition (Basic) provides data storage, access, disaster recovery, and security services that are more independent compared to those provided by the Individual Edition, thus more suitable for enterprises.
Enterprise Edition (Standard)
TCR Enterprise Edition (Standard) provides the image deployment blocking feature and more image distribution features, besides those provided by the Enterprise Edition (Basic). Quotas for certain features are also increased.
Enterprise Edition (Advanced)
TCR Enterprise Edition (Advanced) provides all features of the Enterprise Edition (Basic), as well as certain additional features such as image signature verification, container image loading on demand, and multi-region nearby access to the same instance. Quotas for certain features are also increased.

Image upload
Single-concurrency (Single-layer) image upload speed
20MB/s
20MB/s
20MB/s
Benchmark test value. Due to factors such as the client software type (Docker or Skopeo), the number of CPU cores, the disk I/O, and the network bandwidth, the actual speed may be lower than the test value.
﻿
Multi-concurrency (Multi-layer) image upload speed
min(COS bandwidth/Number of concurrent uploads, 20 MB/s)
min(COS bandwidth/Number of concurrent uploads, 20 MB/s)
min(COS bandwidth/Number of concurrent uploads, 20 MB/s)
Before the Cloud Object Storage (COS) bandwidth limit is reached: 20 MB/s
After the COS bandwidth limit is reached: The theoretical value is approximately equal to the COS bandwidth divided by the number of concurrent uploads. For COS bandwidth limits, see COS Specifications and Limits.
﻿
Number of concurrent uploads

10
Benchmark test value for a layer size of 256 MB. The upload rate will decrease when the limit of concurrent uploads is exceeded.
Image synchronization
Synchronization duration
Not supported
30 minutes
30 minutes
This is the normal synchronization duration for images of 1 GB. In rare cases, the duration may be longer. The overall duration is affected by the number of concurrent tasks, and the average duration increases with the number of tasks.
﻿
Number of concurrent synchronization tasks
Not supported
Maximum value of 10
Maximum value of 10
Image synchronization tasks and image replication tasks share the same concurrent task quota pool. When the number of concurrent synchronization tasks exceeds the limit, synchronization efficiency is affected, and the failure rate increases.
Image replication
Replication speed
Not supported
Not supported
Lower than 40 MB/s
Benchmark test value. Limited by the COS bandwidth, the actual speed may be lower than the test value. For details, see COS Specifications and Limits.
﻿
Replication duration
Not supported
Not supported
Image size/Replication speed
The replication duration is affected by the COS cross-bucket object replication rate. The theoretical value is approximately equal to the image size divided by the replication speed. The overall duration is affected by the number of concurrent tasks. The replication duration increases when the number of concurrent tasks exceeds the limit.
﻿
Number of concurrent replication tasks
