AWS EC2 instances and 32 bit

Some legacy applications including pre 11 Oracle COTS software only run on 32 bit.  Keep this in mind when moving a 32 bit based application to EC2:   These are the instance types that support 32 bit:

1. m1.small : Memory 1.7 GB CPU : 1
2. m1.medium : Memory 3.75 CPU : 2
3. c1.medium : Memory 1.7 GB CPU : 5 ECU
4. t1.micro : Memory .615 GB CPU: 1 ECU variable

 ON Windows,  WoW64 on Windows Server x64 can be used to run a 32 bit application.
