What are the core principles of AWS architecture for small businesses?

Design for reliability, security, and cost control. Use multiple Availability Zones, managed databases, autoscaling or serverless, a CDN for static assets, encryption with KMS, least‑privilege IAM, and centralized logging and alerts. Keep components stateless and automate builds and deployments where possible.

Architecture & Design

Reliable, secure, and cost‑aware patterns from day one.

Foundational patterns

  • VPC with public and private subnets across ≥2 AZs
  • Managed databases (RDS/Aurora) with backups
  • Stateless app tier behind an Application Load Balancer
  • Autoscaling or serverless where practical
  • CloudFront CDN + S3 for static assets
  • Centralized logging, metrics, and alarms

Security by default

  • MFA on all users; least‑privilege IAM roles
  • KMS‑backed encryption at rest and in transit
  • WAF + Shield, Security Groups, and subnet ACLs
  • Backup policies with tested restores
