1. A method comprising: receiving an indication of at least one node of a plurality of nodes to migrate from an enterprise network to a cloud computing infrastructure, the indicated node comprising a first virtual machine; determining, by a processing device, a network ontology for the indicated node, the network ontology being created for the indicated node using a data collection agent deployed to the indicated node to identify related nodes of the plurality of nodes that have direct and indirect communication relationships with the indicated node, the related nodes comprising the network ontology describing current state of the plurality of nodes and the related nodes, the related nodes comprising a second virtual machine, the network ontology being updated using data collection agents comprised by the plurality of nodes; adding the indicated node and at least one node of the related nodes for the indicated node to a migration group; preparing a migration-configuration file for each node of the migration group, the migration-configuration file comprising service level agreement (SLA) information; deploying a migration agent to each node of the migration group; and migrating the migration group to the cloud computing infrastructure, wherein each node of the migration group is migrated using a corresponding migration-configuration file to generate an SLA for each node of the migration group with a provider of the cloud computing infrastructure in view of SLA information from the corresponding migration configuration file.
