To control network traffic at the individual User VM (UVM) subnet level, creating a custom security group is the appropriate action. This approach allows for fine-grained control over inbound and outbound traffic rules that can be applied to specific subnets or individual instances within those subnets.

Custom Security Group:

Custom security groups enable administrators to define specific traffic rules tailored to the needs of individual subnets or VMs. This includes specifying allowed IP ranges, ports, and protocols.

By applying these custom security groups to the UVMs, the organization can control access and enhance security according to their policies and requirements.

Steps to Create a Custom Security Group:

Navigate to the AWS Management Console and go to the VPC service.

Select 'Security Groups' under the 'Security' section.

Click on 'Create Security Group' and define the name, description, and VPC.

Add inbound and outbound rules according to the desired traffic control policies.

Attach the custom security group to the UVMs or subnets in question.

Nutanix Best Practices for Security Groups

When performing a migration from an NC2 environment to a Nutanix on-premises environment, the task should be performed using the NC2 Prism Central. This is because NC2 Prism Central provides a centralized management interface that allows administrators to manage and migrate workloads between cloud and on-premises environments seamlessly.

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.

To support Nutanix's native Local Key Manager (LKM) for data encryption in a cost-effective manner, a minimum of three nodes is required. This ensures that there is enough redundancy and reliability for the encryption services to function properly, complying with best practices for distributed key management.

In the NC2 console, an organization is used to segregate clusters based on specific requirements. This segregation allows administrators to manage clusters more effectively by grouping them according to business units, projects, or other criteria. This organizational structure helps in maintaining clear boundaries and applying specific policies or permissions to different clusters within the same NC2 environment.
