Cloud platform architecture

AWS landing zones shaped to workload ownership

Separate accounts, identity, networks, and managed services deliberately so modernization does not outrun operational control.

Active Cloud Spec

Enterprise Multi-Account Landing Zone (Control Tower)

Segregating production, staging, shared infrastructure, and security audit logs across distinct AWS accounts with automated Service Control Policies (SCPs).

01. Account & IAM BoundaryIAM & SCPs

Account Topology

AWS Organizations: Root -> Core OU (LogArchive, SecurityTooling) -> Workloads OU (Prod, Staging)

Dedicated account boundaries isolate blast radius and limit permissions at the organization root level.

Guardrails

Root: AWS Control Tower

Security: Centralized GuardDuty & AWS Config

Log Archive: S3 Object Lock Write-Once

SCPs: Deny region usage outside us-east-1 / eu-west-1

Service Control Policies Enforce Blast Radius Containment

02. Compute & Network RoutingVPC & Runtimes

Compute Pattern

AWS Transit Gateway interconnects VPCs across accounts with centralized egress firewall

Direct Connect / Site-to-Site VPN terminates in Core Network account

Network Security

VPC Endpoints (PrivateLink) route S3 and DynamoDB traffic over AWS private backbone

Private Subnets with WAF Shield and Transit Gateway Peering

Architectural Fit

When AWS Cloud Platforms Fit

You are building enterprise-grade multi-tier applications requiring deep ecosystem services (Aurora, ECS, Lambda, DynamoDB, S3).
Your organization requires strict compliance boundaries, multi-account separation (Control Tower), and fine-grained Service Control Policies (SCPs).
Workloads span global regions requiring low-latency edge delivery (CloudFront) and automated multi-region disaster recovery.
Infrastructure requires extensive integration with enterprise networking (Transit Gateway, Direct Connect, PrivateLink).

Boundary Analysis

When Google Cloud, Azure, or Vercel Fits Better

Your primary architectural gravity is petabyte-scale real-time SQL analytics and machine learning (choose Google Cloud & BigQuery).
You are deploying a lightweight frontend/Next.js application where serverless PaaS simplifies operations (choose Vercel).
Your organization is built natively around Microsoft Active Directory and .NET ecosystem enterprise agreements (choose Microsoft Azure).

Engineering Rigor

AWS Production Architecture Best Practices

01. PRINCIPLE

Shared Responsibility Rigor

Recognizing that while AWS secures the physical cloud facilities and hypervisors, customer teams own 100% of IAM, encryption, network exposure, and OS patching.

02. PRINCIPLE

Zero Long-Lived Access Keys

Enforcing IAM Identity Center with temporary STS assume-role credentials and Workload Identity for CI/CD runners, completely eliminating static IAM secret keys.

03. PRINCIPLE

Cost & Anomaly Guardrails

Configuring automated AWS Budgets, Cost Anomaly Detection, and automated resource tag policies to prevent surprise bill escalation.

04. PRINCIPLE

Strict Multi-Account Separation

Isolating Production, Staging, and Security accounts under separate AWS account IDs to minimize operational blast radius.

Next Architecture Step

Discuss Your AWS Cloud Infrastructure

Design multi-account Control Tower landing zones, containerize services with ECS Fargate, set up EventBridge serverless pipelines, and establish disaster recovery runbooks with our cloud architects.

Frequently Asked Questions About AWS Cloud Architecture

Do you claim AWS partnership or certification here?

No. This page describes architecture capability. Partnership or certification claims require separate verified evidence.

Does AWS guarantee lower cost than other clouds?

No. Cost depends on architecture, usage, and governance. We do not invent savings percentages.
