ACAI PROVISIO Overview

Situation

In large enterprises, individual baselining and hardening across extensive AWS account landscapes lead to inconsistent security standards, high operational overhead, and increased compliance risks.

Goals:

  • Standardization: Establish uniform security configurations while accommodating specific cluster needs.
  • Automation: Streamline deployments to reduce errors and accelerate provisioning across all accounts.
  • Compliance & Scalability: Enhance regulatory compliance and create a scalable infrastructure adaptable to diverse account clusters.

PROVISIO-OVERVIEW

Expected Outcomes: Consistent, automated security measures across all AWS accounts, reduced manual management, improved compliance, and a scalable infrastructure that meets the evolving demands of large enterprises.

Solution

ACAI PROVISIO empowers organizations to implement robust security baselines and hardening measures across their AWS accounts using Terraform, addressing the native limitations in multi-region and multi-account scenarios.

It empowers organizations to enforce robust security baselines and hardening measures across their AWS accounts using Terraform (or OpenTofu).

It simple allows a native deployment to multi-region and multi-account environments by enabling:

  • Multi-Region Management: Deploy consistent AWS resources across various regions from a single configuration.
  • Multi-Account Provisioning: Streamline the application of unified security policies across numerous AWS accounts.
  • Terraform-Native Integration: Leverage Terraform for infrastructure-as-code while addressing its inherent multi-region/account challenges.
  • Precise Resource Allocation: Use account metadata to define rule-based, targeted resource deployments.
  • Automated Resource Deployment: Ensure immediate compliance and standardization across your entire AWS infrastructure.
  • Customizable Provisioning Templates: Adapt resource configurations to meet evolving organizational needs.

These features enable rapid, compliant, and secure AWS deployments, ensuring that organizations maintain high security standards across their cloud environment.

PROVISIO-SOLUTION

PROVISIO introduces a flexible approach to provisioning by separating the definition of Terraform packages from the specification of account clusters and the details of how each package should be deployed. Specifically:

Terraform Packages

You start by defining one or more Terraform packages—essentially templates or modules—that outline the resources and configurations you want to apply (for example, security baselines, network setups, or logging configurations).

AWS Account Clusters

Instead of managing each AWS account individually, you group accounts into logical clusters. These clusters can represent business units, environments (e.g., development, production), or any other segmentation strategy. Each cluster may require different variations of the baseline or additional customizations.

Deployment manifests

A deployment manifest serves as the “linking layer” that maps each Terraform package to the relevant account cluster(s). Within this manifest, you specify parameters—such as regions, resource tags, or security policies—tailored to each cluster’s needs. This allows you to selectively deploy the same package with different configurations to multiple clusters.

PROVISIO-CONCEPT

Why This Matters

  • Dynamic Rendering: PROVISIO takes these three components (package definitions, account clusters, and deployment manifests) and dynamically generates the exact Terraform configurations needed. This means you can easily adjust which accounts receive which resources, and how those resources are parameterized, without duplicating or manually editing large amounts of code.

  • Scalability & Consistency: By abstracting deployment logic away from the Terraform code itself, PROVISIO helps maintain consistency across dozens—or even hundreds—of AWS accounts. When a new account or region is added, you simply update the manifest and let PROVISIO handle the rest.

  • Adaptability: Because the deployment manifest decouples package definitions from cluster definitions, you can rapidly evolve both. For example, updating a package to include new security checks or adding a new cluster with specialized requirements doesn’t force a complete rework of existing infrastructure code.

In short, PROVISIO’s dynamic rendering and manifest-driven approach gives large enterprises the best of both worlds: centralized standards (consistent security baselines) and flexible customization (tailoring each cluster’s deployment as needed), all while streamlining multi-account, multi-region AWS operations.
