In various embodiments, a method of transferring data between datacenters may be performed. The method may include running a first plurality of host programs and a first plurality of encryption units at a first datacenter. The method may further include establishing, between the first datacenter and a second datacenter, secure communication connections between each of the first plurality of encryption units and a corresponding one of a second plurality of encryption units running at the second datacenter. The method may further include transferring, by the first datacenter, data from the first plurality of host programs to a second plurality of host programs running at the second datacenter.
