Abstract: Provided is a cluster node recommendation system. A method of controlling the cluster node recommendation system includes: inputting user selection information from a user, the user selection information including at least one of a cloud vendor, an Information Technology (IT) resource size, and a free resource size; checking resource requirements of a designated application; outputting a node configuration by inputting the input user selection information and the checked resource requirements of the application to an artificial intelligence module; verifying validity by arranging a container in which the application is executed, in the output node configuration; and providing a final node configuration in which validity verification is made, to the user.
