At SC17 Huawei unveiled Xilinx FPGA-Powered Cloud Server to North America. See the PR here.  We were part of a video transcoding and machine learning demo which was running on the Xilinx booth at SC17. We also took part in the Heterogeneous High Performance Reconfigurable Computing Workshop (H2RC) as well as the Xilinx Developer Lab: Accelerating Applications on AWS

Xilinx is clearly the market leader when it comes to public Clouds with FPGAs. See the picture below showing 6 public Clouds (source: Xilinx booth at SC17):
