1. VMware Aria Operations Architecture

VMware Aria Operations is designed to provide a scalable and resilient architecture, allowing enterprises to manage hybrid cloud, multi-cloud, and VMware environments efficiently.

1.1. High-Level Architecture Components

Aria Operations consists of the following core components:

  • Global Manager (Aria Hub): Manages multi-cloud operations across regions and cloud providers.
  • Collector Nodes: Gathers metrics, logs, and events from vSphere, NSX, storage, and applications.
  • Analytics Engine: Processes collected data and applies AI-driven insights.
  • UI and API Layer: Provides a user interface and REST APIs for automation and integrations.
  • Persistence Layer (Cassandra and FSDB): Stores historical data for long-term trend analysis.

1.2. Node Types in Aria Operations

Aria Operations consists of different node types in a cluster deployment:

  • Master Node: Controls the cluster and provides UI/API access.
  • Replica Node (HA setup only): A backup for the master node in case of failure.
  • Data Nodes: Stores and processes analytics data for scalability.
  • Remote Collector Nodes: Used for data collection from remote sites without affecting cluster performance.
Node TypeFunctionBest Practices
Master NodeControls cluster and UI accessAlways deploy with a Replica Node for HA
Replica NodeBackup for Master Node (only in HA mode)Required for high availability setups
Data NodesStores and processes metrics & logsRecommended for large deployments
Remote Collector NodesCollects data without impacting cluster performanceUse for multi-site environments

Best Practice: For large-scale deployments, use Remote Collector Nodes to optimize data collection and reduce performance impact on the core Aria Operations cluster.

  1. Create a new alert definition (Alerts > Create Alert).
  2. Set Condition: “If CPU Usage > 95% for 10 minutes”.
  3. Attach an Automated Action:
    • Use vRealize Orchestrator workflow: Restart Virtual Machine
    • Trigger a PowerCLI script (via webhook):
$HighCPUVMs = Get-VM | Get-Stat -Stat cpu.usage.average | Where-Object { $_.Value -gt 95 }
$HighCPUVMs | Restart-VM -Confirm:$false

Best Practice: Combine Aria Operations alerts with PowerCLI automation to auto-scale workloads dynamically.
