This topic describes specific memory instance type families, and lists the specific instance types within each of the instance type families. Specifically, the instance type families to be described are: memory instance type family r5, memory-optimized instance type families with enhanced performance re4 and re4e, memory optimized instance type family with enhanced network performance se1ne, and memory-optimized instance type family se1.
r5, memory instance type family
