AWS Landing Zone with Terraform for Scalable AI Infrastructure

Key Challenges

Single-Account Architecture — Datareel’s entire infrastructure operated within a single AWS account, with no separation between production, staging, and development workloads. This flat structure created security risks, made blast radius containment impossible, and prevented the implementation of environment-specific access controls.

Manual Provisioning — Infrastructure provisioning was a manual, time-intensive process taking approximately 48 hours per environment. Each new client onboarding or environment setup required hands-on configuration, creating bottlenecks and delaying time-to-market for new verticals.

Lack of Governance — Without centralized policies or guardrails, teams could provision resources without oversight. There were no preventive controls to enforce tagging standards, restrict resource types, or ensure compliance with organizational policies across accounts and regions.

Compliance Limitations — As Datareel expanded into regulated industries — healthcare (HIPAA), financial services (RBI), and European markets (GDPR) — the existing infrastructure lacked the architectural controls needed to demonstrate compliance. Sensitive data processing without environment isolation created audit risks.

Operational Inefficiencies — Manual infrastructure management led to configuration drift between environments, inconsistent security postures, and a high volume of operational incidents. The engineering team spent disproportionate time on infrastructure firefighting rather than product development.

Our Approach

Kansoft’s cloud engineering team executed a governance-first infrastructure transformation:

Governance-First Design — Started with compliance and security requirements rather than retrofitting them. Mapped HIPAA, GDPR, and RBI compliance controls to AWS architectural patterns before writing any Terraform code.

Multi-Account Architecture — Designed an AWS Organizations-based multi-account structure with dedicated accounts for production, staging, development, security, logging, and shared services, ensuring workload isolation and blast radius containment.

Terraform-Driven Automation — Built a comprehensive library of reusable Terraform modules for networking, compute, storage, IAM, and security resources, enabling consistent, version-controlled infrastructure provisioning across all accounts.

GitOps Enablement — Implemented a GitOps workflow where all infrastructure changes flow through version-controlled repositories, peer-reviewed pull requests, and automated deployment pipelines, ensuring auditability and reducing human error.

Self-Service Infrastructure — Created self-service templates enabling development teams to provision compliant environments independently, removing the infrastructure team as a bottleneck while maintaining governance guardrails.

Phased Delivery — Executed the transformation in phases: foundation (accounts, networking, IAM), automation (Terraform modules, CI/CD), governance (policies, monitoring), and optimization (self-service, cost management).

Solutions Delivered

Multi-Account Landing Zone — Deployed a production-grade AWS landing zone using AWS Organizations with dedicated accounts for each environment and function. The architecture enforces workload isolation, centralized logging, and cross-account security monitoring.

Terraform Module Framework — Built a library of composable, versioned Terraform modules covering VPC design, compute provisioning, storage configuration, IAM policies, and security controls. Teams use these modules to provision infrastructure consistently across all accounts.

GitOps CI/CD Pipeline — Implemented a fully automated deployment pipeline where infrastructure changes are defined in code, reviewed through pull requests, validated by automated tests, and deployed through CI/CD — eliminating manual provisioning entirely.

Policy-Driven Governance — Deployed preventive and detective controls using Sentinel and Open Policy Agent (OPA) to enforce tagging standards, restrict non-compliant resource types, validate security configurations, and ensure all provisioned infrastructure meets organizational and regulatory requirements.

Secure Networking — Architected cross-account networking using AWS Transit Gateway with centralized egress, VPC peering, and network segmentation ensuring secure communication between accounts while maintaining isolation between environments.

Secrets & Access Management — Implemented centralized secrets management using AWS Secrets Manager with cross-account access patterns, automated secret rotation, and fine-grained IAM policies ensuring least-privilege access across all environments.

Why Kansoft

Kansoft’s deep expertise in cloud architecture, infrastructure automation, and compliance-driven design made them the ideal partner for Datareel’s infrastructure transformation. The team’s ability to design governance-first architectures — rather than bolting compliance onto existing infrastructure — ensured Datareel could confidently serve regulated industries from day one. By combining Terraform automation with GitOps practices and policy-driven guardrails, Kansoft delivered a foundation that scales with Datareel’s growth while maintaining security and compliance posture.
