    • A-E
      availability zone

      A physical region where resources use independent power supply and networks. AZs are physically isolated but interconnected through the internal network. To enhance application availability, you are advised to create instances in different AZs.

        File System

        A file system provides users with shared file storage service through NFS. It can be used to access network files remotely. After users create shared directories in the management console, the file system can be mounted to multiple ECSs and is accessible through the standard POSIX interface.

          Network Attached Storage

          NAS is a method of file sharing. With NAS, a storage system has its own file systems inside and provides the file access service through Network File System (NFS).

          Network File System

          Network File System (NFS) is a distributed file system protocol that allows different computers and operating systems to share data over a network. Application programs on client computers use NFS to access data on server disks. NFS is a method for sharing disk files between UNIX-like systems. SFS supports NFS v3 currently.

          • R

            Regions are divided from the dimensions of geographical location and network latency. Public services, such as Object Storage Service (OBS), Virtual Private Cloud (VPC), and Image Management Service (IMS), are shared within the same region. Users can select a region closest to them to reduce access latencies.

            Scalable File Service

            Scalable File Service (SFS) is high-performance file storage that is scalable on demand. SFS file systems support standard file access protocols and can be mounted to Elastic Cloud Servers.
