1. Introduction

Modern data centers demand not just agility, but integrated automation, visibility, and compliance across the network stack.
NSX-T 4.x provides robust software-defined networking and security, while the VMware Aria Suite (formerly vRealize) unifies automation, monitoring, and compliance at scale.

This guide shows how to fully integrate NSX-T with the Aria Suite for production-ready deployments, including YAML and PowerShell samples, and diagram to document your environment with precision.

2. Architecture Overview: NSX-T and Aria Suite

The integration combines:

• NSX-T 4.x: Network virtualization, microsegmentation, routing, and distributed firewall
• Aria Automation: Blueprint-driven provisioning, Infrastructure as Code (IaC)
• Aria Operations: Real-time monitoring, network health, performance analytics, custom dashboards
• Aria Compliance: Policy validation against CIS, PCI, and custom controls with automated remediation

Integration Flow:

• Aria Automation provisions and configures NSX-T resources
• Aria Operations ingests and visualizes NSX-T telemetry, enabling rapid troubleshooting
• Aria Compliance benchmarks settings, automates remediation, and documents policy status

3. Integration Prerequisites

Before you begin, ensure:

• NSX-T Data Center 4.x deployed and healthy (Manager, Edge, Transport Nodes)
• VMware Aria Suite 8.x (Aria Automation, Aria Operations, Aria Compliance)
• Service accounts:
  Create API users in NSX-T and Aria, following the principle of least privilege
• Network connectivity:
  Ensure bi-directional communication between Aria Suite VMs and NSX-T Manager/API
• Licensing:
  Aria Suite Advanced or Enterprise
• SDKs/CLI:
  PowerCLI, PowerNSX, and Python SDKs for API integrations

4. Automating NSX-T with Aria Automation

Overview

Aria Automation enables full Infrastructure-as-Code (IaC) with NSX-T.
You can create, configure, and delete NSX-T objects (segments, routers, firewalls) using YAML blueprints and PowerShell modules.

Sample YAML Blueprint: NSX-T Logical Switch and Segment

formatVersion: 1
inputs:
  networkName:
    type: string
resources:
  Cloud_NSX_Network_1:
    type: Cloud.NSX.Network
    properties:
      name: '${input.networkName}'
      networkType: routed
      constraints:
        - tag: 'prod'
      nsxTransportZone: 'Overlay-TZ'
      nsxGateway: 'Tier1-Gateway'

---

PowerShell: NSX-T Segment Creation via Aria Automation

# Requires VMware.PowerNSX and PowerCLI modules
Connect-NsxServer -Server "nsxt-manager.lab.local" -User "aria-api" -Password "StrongPassword"
New-NsxLogicalSwitch -Name "App-Prod-Segment" -TransportZone "Overlay-TZ" -ReplicationMode "MTEP"
Disconnect-NsxServer

5. Operational Visibility with Aria Operations

Overview

Aria Operations provides a single pane of glass for monitoring the health, security, and performance of your NSX-T infrastructure.
It collects metrics from physical and virtual fabric, overlays, distributed firewalls, and microsegmentation.

---

Visibility Topology

---

Custom Dashboards and Alerts

• Custom NSX-T Dashboard:
  Visualize logical switches, distributed firewall rules, segment health, and traffic patterns (north-south/east-west).
• Sample Alert:
  Alert if any segment reports more than 2% packet loss over 10 minutes.

alertDefinition:
  name: "NSX-T Segment Packet Loss"
  condition: "segment.packetLossPercent > 2"
  severity: "Warning"
  notification: "SendEmail"

---

6. Continuous Compliance with Aria Compliance

Overview

Aria Compliance benchmarks NSX-T against CIS, PCI DSS, and custom controls.
It enables automated scanning, reporting, and even API-driven remediation for common network security standards.

Automated Compliance Policy Examples

CIS Benchmark (YAML sample):

profile: "CIS_NSXT_4.x"
rules:
  - id: "1.1"
    description: "Ensure HTTPS is enabled for NSX-T Manager"
    check: "api:GET:/api/v1/cluster/status | assert:connectionProtocol==HTTPS"
    remediation: "Enable HTTPS only mode via API"

---

PCI DSS (PowerShell Sample):

# Check NSX-T Firewall for PCI DSS segment isolation
Connect-NsxServer -Server "nsxt-manager.lab.local" -User "compliance" -Password "StrongPassword"
$rules = Get-NsxFirewallRule | Where-Object { $_.Section -eq "PCI-Segment" }
$nonCompliant = $rules | Where-Object { $_.Action -ne "Drop" }
if ($nonCompliant) { Write-Host "Non-compliant rules detected!" }
Disconnect-NsxServer

---

Custom Policy (YAML Sample):

policy:
  id: "custom-nsx-t-control"
  description: "Block inter-segment traffic except specific allowed ports"
  control: "Deny all except 80,443 from Web to App segment"
  enforcement: "NSX-T Distributed Firewall"

---

7. Conclusion and Best Practices

Integrating NSX-T with the VMware Aria Suite transforms network operations by delivering:

• Automated provisioning: Infrastructure as Code, consistent environments, fewer errors
• Centralized visibility: Fast troubleshooting, proactive alerting, SLA tracking
• Continuous compliance: Ongoing validation, automated remediation, audit readiness

Best Practices:

• Use service accounts with least privilege for all integrations
• Version all YAML blueprints in source control (Git)
• Create custom dashboards and policy rules for your environment
• Schedule regular compliance scans and act on findings automatically
• Share architecture using the included diagram for consistency
