An information processing system comprising an information processing device and a portable information terminal that allow communication therebetween, each of said information processing device and said portable information terminal using a cloud service provided by at least one service providing server over a network, wherein said portable information terminal includes: an application detection part for detecting a running application (31, 32, 33); wherein said portable information terminal further includes: a management part for managing said running application (31, 32, 33) and the cloud service to which said running application connects, associated with each other; a destination information generation part for generating destination information required for said information processing device to use the cloud service to which said detected running application connects based on the information managed by said management part; and a information transmission part for sending said destination information to said information processing device while the communication with said information processing device by a short-range wireless communication, which is a different way from a communication way taken by said portable information terminal to use the cloud service, is available, and said information processing device includes: an information receipt part for receiving information from said portable information terminal while the communication with said portable information terminal by a short range wireless communication, which is a different way from a communication way taken by said information processing device to access the cloud service, is available; a destination setting part for automatically configuring the destination to connect to the same cloud service as that used by said running application on said portable information terminal in accordance with said destination information received from said portable information terminal while the communication with said portable information terminal is available; and a data processing part for connecting to the cloud service over the network to send and receive data based on the destination configured by said destination setting part. an application detection part for detecting a running application (31, 32, 33); wherein said portable information terminal further includes: a management part for managing said running application (31, 32, 33) and the cloud service to which said running application connects, associated with each other; a destination information generation part for generating destination information required for said information processing device to use the cloud service to which said detected running application connects based on the information managed by said management part; and a management part for managing said running application (31, 32, 33) and the cloud service to which said running application connects, associated with each other; a destination information generation part for generating destination information required for said information processing device to use the cloud service to which said detected running application connects based on the information managed by said management part; and a information transmission part for sending said destination information to said information processing device while the communication with said information processing device by a short-range wireless communication, which is a different way from a communication way taken by said portable information terminal to use the cloud service, is available, and said information processing device includes: an information receipt part for receiving information from said portable information terminal while the communication with said portable information terminal by a short range wireless communication, which is a different way from a communication way taken by said information processing device to access the cloud service, is available; a destination setting part for automatically configuring the destination to connect to the same cloud service as that used by said running application on said portable information terminal in accordance with said destination information received from said portable information terminal while the communication with said portable information terminal is available; and a data processing part for connecting to the cloud service over the network to send and receive data based on the destination configured by said destination setting part. an information receipt part for receiving information from said portable information terminal while the communication with said portable information terminal by a short range wireless communication, which is a different way from a communication way taken by said information processing device to access the cloud service, is available; a destination setting part for automatically configuring the destination to connect to the same cloud service as that used by said running application on said portable information terminal in accordance with said destination information received from said portable information terminal while the communication with said portable information terminal is available; and a data processing part for connecting to the cloud service over the network to send and receive data based on the destination configured by said destination setting part.
