New region support
I modified CloudFormation template to support newer AWS region. I added support for two missing regions:
Change NAT AMIs to use HVM virtualization type
I changed NAT AMIs to use HVM Virtualization Types, since PV(Paravirtual) virtualization type is not supported in new regions.
Change instance type
I changed instance type to
m4.large
since M3 type is not supported in new regions. Since it's almost twice expensive compared to existingm3.medium
, I thought about using cheaper instance type liket2.medium
, but since it doesn't have a consistent performance I decided to use standard M4 instance type instead. Feel free to modify it to another instance type.
