Niche Player: Fujitsu

Fujitsu is an IT outsourcing leader in Asia. The Japanese electronics giant has offered cloud infrastructure services to its global customer base since 2010.

In 2016, Fujitsu rolled out a new, OpenStack-based platform called K5, one intended to deliver a consistent service across public cloud, hosted private cloud and outsourced private clouds.

The predecessor offering, S5, is still available, though. Fujitsu also has legacy offerings in certain parts of the world that use different technologies.
