Abstract: A non-transitory computer-readable recording medium stores an information processing program for causing a computer to execute processing including: receiving a notification in response to an abnormality in a first system on a cloud; and blocking, in response to the reception of the notification, input and output of the first system by using a serverless function that creates a system by using resources on the cloud, and performing switch processing of creating, on the cloud, a second system to which a function of the first system is shifted.

Abstract: A non-transitory computer-readable recording medium stores a program for causing a computer that operates as an operation node in an information processing system which includes the operation node, a standby node corresponding to the operation node, and a network node which relays communication from a client node to the operation node or the standby node, to execute a process including: acquiring first information that is an output of a serverless function executed by the information processing system and indicates a result of coupling checking by the serverless function for a first service used for monitoring of the network node by the operation node; and controlling whether or not to switch a node of an access destination by the client node via the network node from the operation node to the standby node, based on the first information.
