Achieving Unified Infrastructure Visibility: A Guide to HCP Terraform with Infragraph (Public Preview)

Overview

Cloud migration promised simplicity, but for many enterprises, it has introduced new complexities. Infrastructure data is scattered across silos, creating a fragmented view of hybrid and multi-cloud environments. Platform teams often resort to manual data consolidation or multiple tools, leading to sprawl, security gaps, and escalating costs. HCP Terraform powered by Infragraph addresses this by providing a centralized, event-driven knowledge graph that offers dynamic, real-time visibility into your entire infrastructure estate. This guide walks you through the public preview, from prerequisites to practical steps for leveraging Infragraph to secure and optimize your infrastructure.

Achieving Unified Infrastructure Visibility: A Guide to HCP Terraform with Infragraph (Public Preview)

Prerequisites

Before diving in, ensure you meet the following requirements:

HCP Terraform Account: An active HashiCorp Cloud Platform (HCP) Terraform account with appropriate permissions.
Geographic Eligibility: Infragraph is currently available in public preview only to qualified US-based HCP Terraform customers.
Infrastructure Data Sources: At least one cloud or on-premises environment connected to HCP Terraform (e.g., AWS, Azure, GCP, VMware).
API Access: Ability to manage API tokens or OAuth integrations for data ingestion.
Basic Knowledge: Familiarity with Terraform workflows and cloud resource management.

Step-by-Step Instructions

Step 1: Verify Your Eligibility

To use Infragraph, confirm that your HCP Terraform organization is part of the public preview. Navigate to the HCP Terraform dashboard and check for the Infragraph tile under "Integrations" or "Preview Features." If you do not see it, contact your HashiCorp account representative to request access. Only qualified US customers are currently enabled.

Step 2: Enable Infragraph in HCP Terraform

Once eligible, enable Infragraph from your organization settings:

Log in to HCP Terraform.
Go to Settings > Infragraph.
Click Enable and accept the terms of use.
Configure the data refresh interval (default: 5 minutes). Shorter intervals provide faster updates but increase API load.

After enabling, Infragraph starts building a knowledge graph from your existing Terraform state files and connected cloud APIs.

Step 3: Connect Your Multi-Cloud Environments

Infragraph ingests data from your entire infrastructure estate. To ensure complete visibility:

Add cloud provider credentials (e.g., AWS IAM roles, Azure service principals) under Integrations.
Optionally, connect on-premises systems via the HCP Terraform agent.
Verify that all resources are being discovered by checking the Asset Inventory section. You should see a unified list of servers, VMs, databases, and network components.

Use the following example API call to trigger a data refresh (replace ORG_TOKEN with your token):

curl -X POST https://api.cloud.hashicorp.com/infragraph/v1/refresh \
  -H "Authorization: Bearer ORG_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"sources": ["aws", "azure"]}'

Step 4: Explore the Knowledge Graph

The knowledge graph visualizes relationships between assets. Access it from the left navigation under Infragraph > Graph View. You can:

Search for specific resources (e.g., “production-web-server-01”).
Filter by provider, region, or tags.
Click on any node to see detailed metadata, owner, and last updated time.

The graph updates dynamically as infrastructure changes, replacing static snapshots with real-time insights. This enables faster investigation of security issues or cost anomalies.

Step 5: Set Up Dynamic Alerts and Views

With Infragraph, you can create proactive alerts based on the knowledge graph:

Navigate to Alerts under Infragraph.
Define conditions, e.g., “unpatch vulnerabilities in any AWS EC2 instance” or “cost spike > 20% in the last hour.”
Choose notification channels: email, Slack, or webhook.
Save and enable the alert.

You can also save custom graph views for your team. For example, create a view showing only resources tagged “production” for quick monitoring.

Common Mistakes

Mistake 1: Neglecting Data Freshness

Infragraph relies on up-to-date data. If you do not configure automatic refreshes or fail to connect all sources, the knowledge graph becomes stale, leading to outdated insights. Always set a reasonable refresh interval and periodically verify that all environments are reporting.

Mistake 2: Overlooking Relationships

The power of Infragraph lies in its ability to show dependencies (e.g., a VM connected to a storage volume). Ignoring these relationships limits your ability to troubleshoot incidents or plan changes. Spend time exploring the graph to understand how resources interact.

Mistake 3: Misconfiguring Access Permissions

Only authorized users should manage Infragraph. If you give too broad permissions, sensitive asset data may be exposed. Use HCP Terraform’s role-based access control to restrict graph viewing and alert creation to platform engineers only.

Mistake 4: Not Integrating with Existing Workflows

Infragraph is most effective when paired with your incident response and cost management processes. Failing to connect alerts to your ticketing system or automation tools (e.g., via webhooks) reduces its impact. Set up integrations early.

Summary

HCP Terraform powered by Infragraph eliminates the silos that plague modern infrastructure management. By providing a unified, event-driven knowledge graph, it gives platform teams real-time visibility into hybrid and multi-cloud environments, helping to secure assets, optimize costs, and respond faster to changes. The public preview is available now for qualified US customers. Follow the steps outlined above to enable Infragraph, connect your data sources, explore the graph, and set up dynamic alerts. Avoid common pitfalls like stale data or narrow permissions, and you will be well on your way to transforming your infrastructure management.
