Method, apparatus, and cloud system for executing an application in a cloud system

An apparatus for executing an application in a cloud system, comprising:

• an application request receiving unit for receiving a request from a first user for executing an application in cloud system;
• a user data receiving unit for receiving, from the first user, user data of the first user related to the executing of the application of the request;
• a user data storage unit for storing the user data, of the first user received, in a first storage area of a computing environment of the cloud system;
• an execution unit for, in the computing environment, executing the application of the request based on the user data of the first user stored to obtain an execution result;
• an execution result storage unit for storing the execution result in a second storage area of the computing environment, wherein, access permission of the first user to the first storage area is a write-only permission, and access permission of the first user to the second storage area is a read-only permission.

A computing device comprising:

• one or more processors;
• and
• a memory for storing instructions that, when executed by the one or more processors, cause the one or more processors to
• receive a request from a first user for executing an application in a cloud system,
• receive, from the first user, user data of the first user related to execution of the application of the request received,
• store the user data of the first user received, in a first storage area of a computing environment of the cloud system,
• execute the application of the request received, in the computing environment, based on the user data of the first user stored, to obtain an execution result, and
• store the execution result in a second storage area of the computing environment, wherein, access permission of the first user to the first storage area is a write-only permission, and wherein access permission of the first user to the second storage area is a read-only permission.
