Abstract
The massive disappearance of data is caused by natural disaster, terrorism, fire accidents and so on. If data is stored on an online storage service, the information system can be resumed speedily. To create web applications, Representational State Transfer (REST)-based APIs are offered in some online storage services. However, to modify the system, we have to migrate application data to the online storage service, and have to change file reading/writing operation to related application codes. In this paper, we propose a conversion method from the operations for local file system into HTTP requests for online storage by converting the source code. In the execution of converted code, the file reading/writing operation through networks causes the access delay. Thus, we present a cache function that stores and operates data on local storage in order to reduce the access delay.
