Oracle has scored some big wins as it takes on larger cloud rivals.

AWS, Microsoft Azure and Google Cloud dominate the US cloud computing market. Oracle, IBM and others continue to fight for market share, leveraging their existing software, services and systems to gain cloud customers.

Oracle has been making significant headway using this strategy. According to Reuters, Oracle has scored contracts with McDonald’s, Albertsons and Humana to move at least some of their business to Oracle’s cloud platform. In addition, Xactly has decided to move the majority of its work to Oracle’s platform.

These are major contracts for one of the underdogs of the industry and should go a long way toward helping Oracle gain ground.
