Microsoft, Google, Cisco, Red Hat, and VMware also rank high up on a survey by IT consulting firm BTC Logic

Amazon and IBM are the "cloud champions" according to a new report, but Microsoft, Google, Cisco, Red Hat, and VMware are also among the list of heavyweights in the emerging cloud computing field.

All tech vendors are embracing the cloud. Even those that don't provide public cloud services are fighting to become the top builders of infrastructures to support emerging cloud networks.

A new quarterly report from BTC Logic, an IT consulting firm, attempts to rank the top cloud players, and puts them into seven broad categories: cloud foundations, infrastructure, network services, platforms, applications, security and management.
