A valid CIDR range: A CIDR (Classless Inter-Domain Routing) range is necessary for creating the subnets within the VPC. This range defines the IP address space for the cluster and its components.
A my.nutanix.com account: This account is required to access Nutanix services, including the NC2 console, manage licenses, and perform other administrative tasks.
AWS Direct Connect and an on-premises Prism Central environment are not prerequisites for deploying an NC2 on AWS cluster. While Direct Connect can be used for enhanced network performance and connectivity, it is not a requirement for deployment. Similarly, having an on-premises Prism Central environment is not mandatory for NC2 deployment on AWS.
Reference:
Refer to the Nutanix documentation on NC2 prerequisites and setup guides, and AWS documentation on VPC and subnet creation.

To resolve the IP conflict issue when an EC2 instance is powered on in a subnet also used by Nutanix NC2, the administrator should block or exclude the IP address used by the NC2 VM from being assigned to EC2 instances. This can be done by configuring the IP address management (IPAM) settings to ensure that the specific IP addresses allocated to the NC2 VMs are not used by EC2 instances, preventing IP conflicts and ensuring smooth operation of both environments.
