Which service is primarily used for data storage in Alibaba Cloud?

The Alibaba Cloud Object Storage Service (OSS) is the primary service used for data storage in Alibaba Cloud. OSS is designed to store and manage large amounts of unstructured data, such as images, videos, backups, and log files, in a highly durable, available, and scalable manner. It supports various operations such as uploading, downloading, and managing data through a simple and flexible web interface or API access.

OSS provides features like data redundancy, multiple storage classes for cost optimization, and integration with other Alibaba Cloud services, making it ideal for businesses that need reliable and efficient data storage solutions. It is particularly beneficial for applications that require access to large datasets or need to store data for long periods.

Other services listed serve different purposes: Function Compute is a serverless computing service for event-driven applications, the Data Transmission Service is focused on data migration and transfer, and the Server Load Balancer distributes incoming traffic across multiple instances to ensure availability and reliability. These services complement the ecosystem but do not provide the core data storage capabilities that OSS does.
