To establish full connectivity between the company’s on-premises datacenter and the AWS cloud, the

following AWS offerings will satisfy this requirement:

AWS VPN: This service allows you to create a secure connection between your on-premises network

or other remote network and your AWS VPC using an IPsec VPN tunnel. It is suitable for low to

moderate bandwidth requirements and provides secure, encrypted connections.

Direct Connect: AWS Direct Connect is a dedicated network connection from your premises to AWS.

It provides a private, high-bandwidth, low-latency connection which is ideal for high-throughput

applications and workloads that need consistent network performance.

Enable IGMP snooping on the AHV hosts:

IGMP (Internet Group Management Protocol) snooping is a feature that listens to IGMP traffic

between hosts and routers. By enabling IGMP snooping on the AHV (Acropolis Hypervisor) hosts, the

switch can intelligently forward multicast traffic only to the ports that have requested it.

This reduces unnecessary multicast traffic on the network and prevents congestion by ensuring that

multicast packets are only delivered to the appropriate endpoints.

Reference:

Refer to the Nutanix documentation on network configuration and best practices for managing

multicast traffic.

For VDI workloads that require GPU acceleration, the g4dn.metal nodes are the appropriate choice.

These instances are equipped with NVIDIA T4 GPUs, which are well-suited for graphics-intensive

applications such as VDI workloads that need GPU acceleration. Other node types like AN36P,

m6g.metal, or AN36 do not provide the necessary GPU capabilities.

When setting up a landing zone for Nutanix clusters on AWS, having only private subnets for cluster

management and user VMs is not sufficient for full cluster functionality. Nutanix clusters often need

to communicate with the internet for updates, patches, and other cloud services.

VPC Configuration:

The VPC already has two private subnets (one for cluster management and one for user VMs).

Additional Requirements:

To access public services like S3 or for the cluster nodes to reach Nutanix services for updates, a

public subnet is essential.

Why Public Subnet for Internet Access?:

A public subnet allows resources within it to communicate directly with the internet, which is

necessary for accessing Nutanix's update servers, applying patches, and other maintenance tasks.

This subnet typically includes an internet gateway, enabling instances in the public subnet to receive

and send traffic directly to the internet.

After the NC2 free trial expires, to continue using all features of NC2 on existing clusters, the

administrator needs to switch to a paid subscription plan.

A paid subscription ensures uninterrupted access to the full range of features and support for NC2

clusters.

Without switching to a paid plan, the features might be limited, and support may not be available,

impacting the cluster's operations and management.

Reference:

Refer to the Nutanix billing and subscription documentation for details on switching from a trial to a

paid plan and the benefits associated with paid subscriptions.
