For more information about Alibaba Cloud storage services, including detailed descriptions, use cases, and solutions, see Alibaba Cloud Storage Family.
Object Storage Service (OSS) is a secure, low-cost, and highly reliable cloud storage service for massive amounts of data. Its capacity and processing power are scalable. OSS provides multiple storage classes for different scenarios, from hot to cold data. This helps you fully optimize your storage costs. | |
Block Storage provides high-performance, low-latency block devices for Elastic Computing Service (ECS) instances. It supports random read and write operations. You can format a block storage device and create a file system on it, just as you would with a physical hard drive. | |
File Storage NAS is a reliable, high-performance distributed file system for compute nodes, such as ECS instances, E-HPC, and container services. It provides shared access and is scalable. Because NAS is based on the POSIX file interface, it is natively compatible with standard operating systems. | |
Cloud Parallel File Storage (CPFS) is a parallel file system. Data is stored on multiple data nodes in a cluster, and multiple clients can access the data at the same time. CPFS meets the high input/output operations per second (IOPS), high throughput, and low latency data storage requirements of large-scale high-performance computing (HPC) clusters. | |
Apsara File Storage for HDFS is a file storage service for compute resources like ECS instances and container services. It meets the distributed storage requirements for performance, capacity, and reliability from distributed computing applications, such as Hadoop. | |
Tablestore is a structured data storage service developed by Alibaba Cloud. It stores massive amounts of structured data and provides fast query and analysis services. Tablestore supports petabyte-scale storage, tens of millions of Transactions Per Second (TPS), and millisecond-level latency. | |
Cloud Storage Gateway is a gateway that can be deployed in on-premises data centers or on Alibaba Cloud. It uses OSS as its backend storage. The gateway provides industry-standard file services (NFS and SMB) and block storage services (iSCSI) to applications running on-premises and in the cloud. |
