I know we can find the max connections by {DBInstanceClassMemory/12582880}(12582880 is the magic number for my AWS resources). However, for db.m4.large (8 GB RAM) I checked online at many places that the maxConnections are 648. However, when I made the calculations, I found
8 * 1000000000/12582880 = 635.7844944877
8 * 1024 * 1024 * 1024 / 12582880 = 682.6684027822
Similarly for db.t2.small
2 * 1000000000/12582880 = 158.9461236219
2 * 1024 * 1024 * 1024 / 12582880 = 170.6671006955
acc to the internet: 150
Please help with finding the correct number. I cannot open MySQL console on the AWS instance due to some restrictions.
