Are 2GB the max amount of RAM per server?
Yes, the C1 server is a 4-core CPU with 2GB of RAM and a 1 Gbit/s network card. Other variation of servers are coming, including x86-based CPUs.
So it's a Raspberry Pi 2 with 1GB of extra RAM and 1Gb/s Ethernet connection or an average smartphone without a display... times 10?
