Ethernet to Cloud

I am new here. I would like to start a new project. I have a device which has Ethernet slot. The data from this device is available at this Ethernet slot. I have also Ethernet to USB cable.
My aim is to take the data from the device via Ethernet to USB and put it in to the cloud.
What is the best way to or which boards are best to use to send data from Ethernet to Cloud?. Also from cloud to Ethernet also supported.

Please suggest me some boards which can fulfill this goal. Thank you.
