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

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.

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.

Within an NC2 environment, the Cluster Protect feature can ensure the protection of:

Nutanix Files: This provides file services within the Nutanix ecosystem, and Cluster Protect can safeguard the data stored in Nutanix Files.

Virtual Machine Disks: This ensures that the data stored on virtual machine disks is protected, providing backup and recovery options for the virtual machines running within the cluster.

To manually create an AWS VPC with Public access to Prism Element for testing purposes, the following components must be created:

VPC: A Virtual Private Cloud to provide an isolated network for the resources.

Delegated Subnets: Subnets within the VPC to segment the network and allocate IP ranges.

Route Tables: To define routing rules for the subnets to ensure proper traffic flow.

NAT Gateway: To enable instances in the private subnets to access the internet.

Internet Gateway: To allow direct internet access to instances in the public subnets.

Load Balancer: To distribute traffic across multiple instances for improved availability and redundancy.

References:Refer to the AWS documentation on VPC creation and Nutanix documentation on network setup for Prism Element access.
