Concepts

Elastic File Service provides a highly scalable file system for   sharing file data in   the cloud environment. It offers high availability, durability, and reliability.

Object-Oriented Storage offers high scalability and durability, capable of storing vast amounts of any type of data, and can automatically handle data redundancy,   fault recovery, and data   distribution.

EVSs provide high-performance, low-latency, scalable block storage. EVSs can be   mounted to elastic cloud servers or physical machines, allowing them to   persistently store data.

Storage   Method

Elastic File Service uses a file storage method. File storage organizes data into hierarchical directories and file structures, allowing users to operate on   files and directories through file paths and names.

Object-Oriented Storage stores data as individual objects. Each   object consists of the data   itself and associated metadata (such as file name, file type, size, etc.).

EVSs use block storage. Block storage divides data into fixed-size blocks (usually a few KB or MB) and accesses them via unique block addresses.

Access   Mode

Elastic   File Service is accessed through network sharing. Users   can mount the file   system on the required elastic cloud server   instances or container instances   and access the shared file system  through standard file system interfaces   (such as NFS, SMB, etc.).

Object-Oriented Storage requires specifying a bucket address and   is accessed through   transport protocols such as HTTP or HTTPS.

EVSs  are similar to PC hard drives and cannot be used   independently. They are   typically accessed through mounting (Mount).   It can be mounted on elastic cloud servers or physical machines, making it visible within the operating   system.

Application   Scenario

Such as   configuration files and log files for applications that   need to be shared,   and in containerized applications, it supports data   sharing and   synchronization between multiple container instances.

For   large-scale data storage and analysis scenarios such as big   data analysis,   data lakes, data backup, and archiving; storage for   static website hosting   solutions.

For use   as a data storage medium on ECSs or physical machines   for data storage and   persistence; high-performance computing scenarios   such as large-scale data   processing and distributed computing.

Capacity

Elastic   File Service can dynamically expand or shrink with   business needs, with a   capacity that can reach up to 10 PB.

Object-Oriented   Storage services have no capacity limits, and   storage resources can be   expanded infinitely.

EVSs   support on-demand expansion, with the minimum expansion   increment being 1 GB,   and a single EVS can be expanded from 10 GB to   32 TB.
