Computer system and search method for environment

A search method for an environment in which an object is to be deployed, which is executed by a computer system,

• the computer system including at least one computer including a processor, a storage device coupled to the processor, and a network interface coupled to the processor,
• the computer system being coupled to a plurality of infrastructure systems each of which provides the environment,
• the search method for an environment including:
• a first step of receiving, by the at least one computer, a search request including an environmental requirement being a condition required for the environment in which the object is to be deployed and a constraint being a condition to be complied with in deployment of the object;
• a second step of searching, by the at least one computer, for the environment that satisfies the constraint and the environmental requirement;
• a third step of changing, by the at least one computer, the environmental requirement in a case where the environment in which the object is deployable does not exist;
• and
• a fourth step of searching, by the at least one computer, for the environment that satisfies the constraint and the changed environmental requirement.
