CPU value       Memory value (MiB)
256 (.25 vCPU)  512 (0.5GB), 1024 (1GB), 2048 (2GB)
512 (.5 vCPU)   1024 (1GB), 2048 (2GB), 3072 (3GB), 4096 (4GB)
1024 (1 vCPU)   2048 (2GB), 3072 (3GB), 4096 (4GB), 5120 (5GB), 6144 (6GB), 7168 (7GB), 8192 (8GB)
2048 (2 vCPU)   Between 4096 (4GB) and 16384 (16GB) in increments of 1024 (1GB)
4096 (4 vCPU)   Between 8192 (8GB) and 30720 (30GB) in increments of 1024 (1GB)
