Google announced on Thursday its cloud unit has won a deal to provide computing and networking resources to Elon Musk’s SpaceX, to assist deliver internet service through its Starlink satellites. The space rocket maker will establish ground stations within Google’s data centers that connect to the Starlink satellites, enabling quick and secure internet services via Google Cloud. This service is expected to be available in the second half of 2021 for enterprise customers, Google said on Friday.

The deal is a big victory for Google as it is about to take share from Amazon and Microsoft in the fast-growing cloud computing market. Investors are relying on Google’s cloud business to boost growth in the event that its advertising business slows down. It’s also an unusual kind of deal for Google or any other cloud provider as it depends mostly on Google’s internal network that connects data centers, instead of simply outsourcing functions like computing power or data storage to these data centers.

“This is one of a kind. I don’t believe something like this has been done before. The real potential of this technology became very obvious. The power of combining cloud with universal secure connectivity, it’s a very powerful combination,” said Bikash Koley, Google’s head of global networking “They chose us because of the quality of our network and the distribution and reach of our network,” said Thomas Kurian, CEO of Google’s cloud group.
