Storage Capacity Unit

Plan and optimize your storage budget with flexible storage services

Both Cost-effective and Flexible in Use

Storage capacity units (SCUs) can be used to offset pay-as-you-go bills of a variety of cloud storage services to streamline your service purchase process.

SCUs can be used along with ECS reserved instances to make it easy to plan your budget on cloud computing resources. In addition, SCUs decouple computing resources from storage resources and allow cloud disks to be attached to or detached from instances, so that cloud resources can match your business requirements more flexibly.

Cost Optimization

Reduces your costs by up to 67% compared with equivalent pay-as-you-go storage.

Resource Reservation

Provides zone-level resource reservation capabilities to meet business continuity requirements while maintaining flexibility.

Flexibility in Use

Available for sale by region. You can choose a deductible product type and a validity period to purchase an SCU in a region. This SCU is then automatically used to offset your bills in the region.
