Red Hat (NYSE:RHT) is helping the European Space Agency (ESA) reach the cloud.

The enterprise software company said Tuesday that it has developed an on-premise, private cloud infrastructure with advanced IT services that includes its open-source Linux operation system for the space agency’s user communities.

Red Hat is the No. 1 provider of Linux, which has become a preferred alternative to the Unix systems that Microsoft (NASDAQ:MSFT) and Apple (NASDAQ:AAPL) have used. The company also has been growing in several other areas, including middleware, storage and virtualization software.
