They run the same RouterOS as all their other hardware, so if you're familiar with one, you're familiar with the other. To be honest I have no idea what the whole "cloud core" series of products was named for. Maybe I'm missing something. I do know the biggest Cloud Core Router is supposed to be able to do around 28 Gbps LAN to WAN speed. 36 core CPU, etc. Ridiculous. I don't need ANYTHING like that, but the little CRS-125 is only $199 retail so it was kind of a no-brainer.
