Most customers are going with Oracle's cloud deployment option for Fusion Applications, according to Leone. And customers are typically employing a "co-existence strategy," running some Fusion modules alongside their existing Oracle applications, rather than ripping and replacing, he said.

Still, some customers are weighing "full-suite deployments" of Fusion, Leone added.

Oracle is planning "a lot of new product introductions" for Fusion over the next year, Leone said.

Some of those will involve additional features for social networking. While some social features were built into Fusion from the start, recent acquisitions by Oracle in the area of social software will allow those capabilities to grow, Leone said. "You'll see social is a key tenet of our road map going forward."

Oracle is eager to show that Fusion Applications are clicking in the marketplace, both to help increase the return on its large investment and to prove that the was worth the effort.
