A Comprehensive Analysis of Alibaba Cloud OSS Object Storage: Unifying Object Buckets, Vector Buckets, and Table Buckets

Alibaba Cloud OSS has launched a unified "object bucket + vector bucket + table bucket" architecture that consolidates unstructured data, vector data, and structured data onto a single storage foundation. Object buckets support a maximum single file size of 48.8TB and data reliability of 12 nines; vector buckets support trillion-scale vector volumes and millisecond-level similarity search; table buckets natively integrate Apache Iceberg, and concurrent write TPS across 500 tables can reach more than 10 times that of self-built Iceberg solutions. The article also breaks down the four-layer cloud-native architecture and hands-on steps such as creating a Bucket, uploading via SDK, and batch operations with ossutil.
