Zero-Trust Cloud Architecture

Describe your infrastructure in plain English. Get a visual architecture diagram, security explanations, and production-ready Terraform with least-privilege IAM — in minutes, not weeks.

bastion — architecture session
I need a batch ETL pipeline from Postgres to a data warehouse, SOC2 compliant.
I'll design that for you. A few questions first:

📊 Expected data volume per day?
🔐 Do you need Customer-Managed Encryption Keys (CMEK)?
🌐 Network isolation requirements?
~50GB/day, yes to CMEK, fully private networking.
✅ Architecture ready. I've selected:

RDS Postgres → AWS Glue → Redshift

Selected Glue over EMR to minimize cluster management. Configured with VPC endpoints to ensure data never traverses the public internet.

The Problem with AI-Generated Terraform

Every AI can generate Terraform. Almost none of it is secure enough to deploy.

🔓

Wildcard IAM Policies

AI tools generate "Resource": "*" because it's easier. One compromised service = full account access.

🌐

Public by Default

Default configurations expose databases and services to the public internet. SOC2 auditors will flag this immediately.

🤷

No Explanations

You get code with zero context. Why was this service chosen? What are the trade-offs? Your CISO will ask. You won't have answers.

Bastion fixes this.

Every architecture is designed with least-privilege IAM, private networking, and plain-English explanations of every decision.

How It Works

From requirements to production-ready Terraform in 4 steps.

01
💬

Describe

Tell Bastion what you need in plain English. "I need a batch ETL pipeline from Postgres to a warehouse, SOC2 compliant."

02
🏗️

Architect

The AI asks constraint questions — scale, compliance, encryption, network isolation — then designs a visual architecture.

Explain

Click any component to see why it was chosen, what alternatives were rejected, and what IAM permissions it requires.

📦

Export

Download production-ready Terraform with strictly scoped IAM roles, VPC isolation, encryption, and a security compliance report.

Built by an SRE. For Platform Teams.

Every line of generated Terraform passes our security compiler.

One IAM role per component

No shared roles. No privilege escalation paths.

No wildcard resource ARNs

Every IAM policy references specific resource ARNs.

Private networking by default

VPC endpoints, private subnets, no public IPs.

Encryption everywhere

At rest, in transit, with CMEK when compliance requires it.

SOC2 & HIPAA ready

Compliance controls enforced automatically.

Checkov validated

Every output passes open-source security scanning.
