Amazon Managed Workflows for Apache Airflow (MWAA) VPC Requirements

Question

From the MWAA [documentation][1] there is a provided template for VPC creation that specifies a CIDR range of /16 and each subnet (public & private) with size of /24.

Are there any specific reasons on the default value? If not, what is the minimum size allowed?

Can we modify the CIDR range starts with 10.192.0.0 in this template?

Accepted Answer

Most of our quick guides, and templates will have a standard /16 range for VPC and a /24 range for Subnet. 
Minimum size for a VPC or Subnet is /28. You can play around with the public and private subnets up to /28.
You can modify the CIDR range of 10.192.0.0 before you create the VPC.
