Comparison with Self-built NAS and Conventional NAS

Alibaba Cloud NAS has many advantages over a self-built NAS on the cloud and conventional NAS products.

Overview OverviewAlibaba Cloud Network Attached Storage (NAS) On-cloud Self-built NAS Conventional NAS
Reliability 99.999999999% data reliability Uncertainty in reliability. Data may be lost during data synchronization between master and slave nodes. 99.9%-99.99% data reliability
Availability No Single-Point-Of-Failure. 99.9% availability. SLA-guaranteed. Uncertainty in stability. Storage services become unavailable during server downtime. Single-Point-Of-Failure
Elastic Storage capacity is elastically scalable and may reach a maximum of several petabytes. Elastic resizing is not supported. Limited storage hardware capacity and long hardware upgrades
Throughput The throughput capacity is horizontally scalable and has a linear relationship with the storage volume. Low throughput which cannot be horizontally scaled. High-end NAS storage devices and a large volume of hardware are required.
Security Supports end-to-end permission management Only supports protocol-level permission management. Supports end-to-end permission management.
Simple Alibaba Cloud NAS is available for use immediately after simple creation, mount and other operations, and can be seamlessly integrated with other Alibaba Cloud products. Self-built NAS on the cloud requires investments in establishing and maintaining file servers, which can be a complicated process. Conventional NAS requires manual management of numerous resources including hardware, storage pools, file systems and protocols. It requires complicated and error-prone operations for a service to use the NAS.
Low costs Alibaba Cloud NAS supports both Pay-As-You-Go and Subscription storage packages and charges fees fully based on the storage volume, without other costs. For disks of self-built NAS ,you need to plan and pay for the maximum usage in advance. Additional server and maintenance costs are also required. Hardware is offered in whole sets regardless of the actual usage, and a large amount of hardware O&M costs are required.

Customer Scenarios

  • Local and Cloud File Sharing
  • Cloud Data Processing
  • Cloud-based NLE System
  • High Performance Website

Local and Cloud File Sharing

Local and Cloud File Sharing


Business system A is deployed in a local data center while business system B is deployed on the cloud. The business data generated by business system A needs to be uploaded to the cloud and used as the input for business system B. Every day 8 TB of data needs to be uploaded.


  • Standard NAS

    The standard NAS provides elastic storage capacity based on the actual business need. The same NAS file system is mounted on both business system A and B to allow file sharing.

  • 1 GB Leased Lines

    The local data center is connected to Alibaba Cloud through 1 GB leased lines. The data generated by business system A can be uploaded to the cloud smoothly.


  • The local data center no longer needs to upgrade storage capacity. Local data is elastically uploaded to and stored on the cloud.

Cloud Data Processing

Cloud Data Processing


Because of the rapid business growth, the logs that are generated every day can fill up the 2 TB disk. Therefore, it is necessary to migrate disk data and expand disk capacity. Data migration causes service interruptions and makes it difficult to perform data analysis.


  • Performance NAS

    Using the performance NAS, hundreds of Web servers can write the business logs into the shared file system without capacity limits. The same file system is mounted on multiple data analysis clusters to perform dynamic analysis.


  • Log migration is no longer needed.

    Dynamic data analysis is supported. The client can obtain the results of data analysis in 10 minutes, instead of waiting 24 hours.
