AI Technical Summary

Technical Problem

Existing cloud application solutions have problems with slow file access response speed and large storage space usage. Especially in cloud gaming scenarios, pre-installed solutions are complex and have limited storage space, while free-installation solutions have slow network access speeds and the storage server becomes a performance bottleneck.

Method used

Combining bind mounts in the host with network mounts of remote directories, access requests are judged through the virtual file system, and remote directories are mounted on demand to decouple file access, reduce storage space usage, and improve access speed.

Benefits of technology

It reduces storage space usage, avoids complex file copying operations, improves file access speed and cloud application startup and running speed, saves bandwidth, and enables cache sharing among different cloud applications.

Abstract

The invention provides a file access method and device.The method comprises the steps that when a cloud application running in a container accesses files under a cloud application directory in the container, if a virtual file system in a host receives a first file access request, whether a first directory in the host has a first identifier or not is judged; if the first directory has the first identifier, judging whether the first directory has a second identifier; if the first directory has the second identifier, the virtual file system sends the second file access request to the first file system for processing; or if the first directory does not have the second identifier, the virtual file system notifies the second file system to mount the remote directory to the first directory through the first file system, and sends the second file access request to the first file system for processing after mounting is completed, at least one of the two problems of low file access response speed and large storage space occupation in the existing scheme can be solved.
