1) The article is from May 2021 2) When I checked today the free Ampere instance was a 1 core, 6GB of memory, 1 Gbps network bandwidth, and up to 2 virtual NICs. Edit: I spoke too soon. After selecting it I was able to increase the CPU count to 4 and 24GB of memory. I provisioned with Ubuntu 20.04, logged in and I see 4 CPUs and 24GB of memory. Cool. The free x86 instance is 1 core, 1GB of memory, 0.48 Gbps network bandwidth, and up to 1 virtual NIC.
