Which storage solution in Alibaba Cloud offers low-cost object storage?

The Alibaba Cloud Object Storage Service (OSS) is designed specifically for storing and managing large amounts of unstructured data as objects. It provides a highly scalable, secure, and durable solution for object storage needs. OSS is particularly well-suited for scenarios such as backup, archive, and serving static content like images and videos due to its cost-effectiveness.

OSS delivers several advantages, including a pay-as-you-go pricing model, which ensures that users only pay for the storage they actually use, making it a low-cost option for object storage. Additionally, it offers high durability and availability, ensuring that data is reliably stored and easily accessible.

In contrast, Alibaba Cloud File Storage is typically aimed at file storage needs, offering a file system interface, while Block Storage is designed for use with cloud-based virtual machines and is optimized for high IOPS performance. Local SSD is meant for applications requiring very high-speed data access, but it is more expensive and less suited for large-scale data storage when compared to OSS.

Therefore, OSS stands out as the most appropriate and cost-efficient solution for object storage within Alibaba Cloud's offerings.
