AT&T to move its 5G mobile network to Microsoft's Azure cloud0
Furthermore, Microsoft confirmed that it will purchase AT&T's Network Cloud platform technology, which the carrier's 5G core network runs on. Furthermore, Microsoft will buy AT&T's engineering and lifecycle management software that is typically used to design and deploy network cloud platforms specifically made for carriers.
Regardless of the acquisitions announced today, AT&T will continue to operate its network and manage customer relationships, it's just that it will now use Microsoft's infrastructure.
Naturally, Microsoft will be responsible for deploying both the software development and the carrier's Network Cloud, as well as for bringing AT&T's existing network cloud to Azure over the next three years. The announcement mentions that neither company is disclosing details on financial terms.
