With the Nutanix AOS Pro licensing, several advanced features and add-on products become available. Specifically, in the AWS cluster deployment wizard, the following add-ons are available:

Files:

Nutanix Files provides a software-defined, scale-out file storage solution that simplifies the management and scaling of unstructured data.

Advanced Replication:

Advanced Replication features in Nutanix include synchronous and asynchronous replication capabilities, allowing for robust disaster recovery and data protection solutions.

DARE (Data-At-Rest Encryption):

DARE ensures that all data stored on Nutanix clusters is encrypted, providing a higher level of security for sensitive information.

These features are included in the AOS Pro licensing tier, offering enhanced data management, protection, and security capabilities.

The requirement for two private subnets in the NC2 cluster configuration workflow serves the same purposes:

One subnet is designated for user VMs, ensuring user workloads are separated from management operations.

The other subnet is designated for cluster management, maintaining the integrity and security of management processes and internal communications.

Traffic from the on-premises network is not permitted by VM and Management security groups:

Ensure that the security groups assigned to the VMs and management interfaces in AWS allow inbound traffic from the on-premises network. Without appropriate security group rules, the traffic will be blocked.

The AWS VPC traffic is blocked by a firewall in the on-premises network:

Check if the firewall on the on-premises network is configured to allow traffic from the AWS VPC. Firewalls may have restrictive rules that block incoming traffic, preventing communication.

References:Refer to AWS documentation on security groups and firewalls and Nutanix documentation on configuring networking for NC2 clusters.

For issues related to cloud hardware support such as EC2 instances, VPC, etc., the public cloud vendor (AWS in this case) should be contacted. AWS provides support and documentation for their infrastructure and services, ensuring that users can get assistance for any hardware or cloud-specific queries.

To ensure that NC2 VMs can access AWS resources without traversing the internet, the administrator can use AWS VPC Peering and Interface Endpoints. Both methods ensure that traffic stays within the AWS network, maintaining security and efficiency.

Interface Endpoint:

Interface Endpoints allow you to privately connect your VPC to supported AWS services. They use AWS PrivateLink to route traffic directly to services within the AWS network, bypassing the public internet.

Steps:

Create an interface endpoint for the required service in the AWS VPC console.

Ensure the security groups and route tables are configured to allow traffic to the interface endpoint.

VPC Peering:

VPC Peering allows the routing of traffic between VPCs using private IP addresses, without the need for internet gateways, NAT devices, or VPN connections.

Steps:

Create a VPC peering connection between the VPCs.

Update the route tables to direct traffic between the peered VPCs.

Ensure security group rules allow the necessary traffic between VPCs.

To deploy an NC2 cluster using an existing AWS network, the NAT Gateway should be placed in a public subnet. A public subnet is one that has a route to an Internet Gateway, allowing the NAT Gateway to provide outbound internet access for resources in private subnets. The NAT Gateway is used to enable instances in private subnets to access the internet while keeping them secure by not exposing them directly to the public internet.

When creating a new NC2 cluster using an existing AWS VPC infrastructure, two private subnets are needed. These subnets are used as follows:

One private subnet for user VMs, which houses the virtual machines that users interact with.

Another private subnet for cluster management, which is used for internal cluster operations and management tasks, ensuring that management traffic is isolated from user traffic for security and performance reasons.

When selecting the NC2 subscription plan from the Nutanix Billing portal, the available options include:

Pay-as-you-Go (PayG): A flexible payment option where users are billed based on their actual usage, providing cost efficiency for variable workloads.

Bring your own License (BYOL): Allows users to utilize existing Nutanix licenses they have purchased, offering a cost-effective way to leverage existing investments in Nutanix software.

References:Refer to the Nutanix billing and subscription documentation for detailed descriptions of subscription plans and their benefits.

Given the company's large spend commitments as part of an AWS Enterprise Discount Program (EDP) totaling $15 million, purchasing Nutanix licenses through the AWS Marketplace ensures that the costs contribute to the EDP commitment.

This approach integrates the Nutanix license costs into the overall AWS spend, thereby maximizing the benefits of the EDP.

Purchasing directly from Nutanix or leveraging existing licenses might not count towards the AWS EDP commitment, and trial licenses are typically for evaluation purposes and do not contribute to the committed spend.

References:Refer to the Nutanix and AWS documentation on licensing and marketplace purchases, and EDP program details.

To ensure that every NC2 on AWS cluster deployed allows full access from the on-premises CVM subnet efficiently, the administrator should create a custom AWS Network Security Group.

Use a key value oftag:nutanix:clusters:externalfor the security group, and set the inbound allow address to the on-premises subnet.

This approach leverages AWS tags to manage security group rules dynamically and ensures that the necessary access permissions are applied automatically to all clusters with the specified tag.

This method reduces the need for manual configuration of each cluster's security group, streamlining the process for a test/dev environment where clusters are frequently created and destroyed.
