Special thanks to Naomi Rampersad for this entry.
AWS has different instance types (T2,M4, M3,C4,C3,X1,R4,R3,etc). The M4 instances are the latest generation of general purpose instances providing a balance of compute, memory, and network resources, and it is a good choice for many applications. We typically stick to the M4 series for our EP and FP builds. You can use m4.2xlarge or m4.4xlarge or go higher and then provision your storage accordingly.
Hope this helps!
