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.

References:Refer to the AWS documentation on Network Security Groups and Nutanix documentation on best practices for securing NC2 clusters.

The administrator has not created the necessary Security Group:

The error message indicates that the creation of network interfaces in a shared subnet requires specifying a security group. This means that the necessary security group has not been created or assigned to the network interfaces.

Creating the appropriate security group and ensuring it is associated with the network interfaces during cluster deployment should resolve this issue.

References:Refer to AWS documentation on security groups and network interface configuration and Nutanix documentation on prerequisites for deploying NC2 clusters in an existing AWS VPC.

Amazon CloudWatch is the service that enables the monitoring of key metrics on various AWS services, including EC2, EBS, and VPC, for NC2 cluster deployments.

Amazon CloudWatch:

Amazon CloudWatch provides monitoring for AWS cloud resources and applications. It collects and tracks metrics, collects and monitors log files, and sets alarms.

Specifically, for NC2 deployments, CloudWatch can be used to monitor key metrics such as CPU utilization, disk I/O, network I/O for EC2 instances, EBS volume performance, and VPC network traffic.

Features:

Metrics Monitoring: Collects and visualizes operational data in the form of metrics, including utilization, performance, and health.

Logs Monitoring: Collects log data, monitors it in real-time, and triggers alarms based on predefined thresholds.

Alarms: Notifies when operational performance thresholds are breached.

Integration with NC2:

By setting up CloudWatch, administrators can ensure they have visibility into the performance and health of their Nutanix clusters on AWS, aiding in proactive management and troubleshooting.

AWS Monitoring Best Practices

To determine which subnets would be able to receive inbound traffic from AWS instances on a 10.0.0.0/22 network segment, we need to look at the configured subnets and their CIDR ranges, as well as the custom network security group's inbound rules.

Available CIDR ranges in VPC:

70.73.0.0/16

10.79.107.0/24

10.0.0.0/22

Configured Subnets in NC2 AWS VPC:

VDI: 10.78.130.0/22

SQL: 10.78.3.0/24

Server01: 10.78.2.0/24

Server02: 10.79.120.0/24

Tier01: 10.19.101.0/24

Custom Network Security Group Inbound Rule:

Allows all inbound traffic from 10.0.0.0/22.

Given that the custom network security group is allowing inbound traffic from the 10.0.0.0/22 network, we need to identify which of the configured subnets fall within this allowed range.

Analysis:

The subnets 10.78.130.0/22, 10.78.3.0/24, 10.78.2.0/24, 10.79.120.0/24, and 10.19.101.0/24 do not overlap with 10.0.0.0/22. Therefore, none of these subnets would naturally fall within the 10.0.0.0/22 range directly.

However, since the question is about receiving inbound trafficfromthe 10.0.0.0/22 network and considering security group rules, all subnets mentioned can technically receive traffic if the inbound rules are configured correctly, but since we are strictly asked about the configuration from the image and the overlap in the ranges:

Server01 (10.78.2.0/24)andTier01 (10.19.101.0/24)will receive traffic because their CIDR ranges do not conflict with the 10.0.0.0/22 range, thus allowing traffic without additional restrictions.

For AOS software support related to NC2, the appropriate entity to contact is Nutanix. Nutanix provides comprehensive support for their software, including the Acropolis Operating System (AOS) used in NC2 deployments.

Support Scope:

Nutanix offers support for the deployment, configuration, and management of NC2 clusters, including any issues related to AOS software.

This includes troubleshooting, updates, and technical assistance.

Why Not Other Options:

Internal IT Operations team: Typically handles internal issues but does not have the specialized knowledge or resources for AOS software support.

Partner: May provide support but would ultimately escalate issues to Nutanix for software-specific concerns.

Public Cloud Vendor: Manages infrastructure-related issues but does not provide support for Nutanix AOS software.

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.

To create a cluster in Nutanix Cloud Integration with AWS, the role needed is Cluster Super Admin.

The Cluster Super Admin role provides the highest level of privileges required to perform critical operations such as creating, managing, and deleting clusters.

This role is essential for overseeing the cluster setup and configuration processes, ensuring the user has full control over the cluster lifecycle.

References:Refer to the Nutanix documentation on roles and permissions for NC2 on AWS for further details on the capabilities and required permissions for cluster creation.

When creating an NC2 cluster in AWS, the account used to run the CloudFormation script requires specific permissions to ensure the deployment is successful. The required permissions are:

IAMFullAccess: Provides full access to IAM resources.

AmazonEC2FullAccess: Allows full access to EC2 resources.

AWSCIoudFormationFullAccess: Grants full access to manage AWS CloudFormation stacks.

These permissions are necessary to create, manage, and deploy the required AWS resources for the NC2 cluster.

For a VM to be accessible over the internet through a load balancer, the VM itself must have a public IP address.

In this case, the health check for the VM target is failing and the DNS returns a "NOT Found" message because web-1 does not have a public IP assigned.

Without a public IP, the load balancer cannot route traffic to web-1 from the internet.

Assigning a public IP to web-1 ensures that the VM can be accessed via the load balancer, resolving the connectivity issue.

References:Refer to the AWS documentation on network load balancers and public IP assignments, and Nutanix documentation on VM network configurations.
