To identify the correct base servers and their actual server configurations, the IT infrastructure is crawled and various telemetry, connection, and network data is analyzed against data sets of other known servers. The digital twin is created to include these base servers and their particular configurations. Then, the digital twin may be deployed on demand in the cloud-computing environment using executable scripts that mimic the base servers and their particular configurations, creating a replication of the IT infrastructure for various purposes (e.g., redundancy, testing, etc.). ## Claims ### Claim 1 A method for creating a digital twin of an IT infrastructure for replicating a portion of the IT infrastructure in a cloud-computing environment, the method comprising: receiving a request to create the digital twin of the IT infrastructure;
