Cloud Architecture

Architecture on cloud platforms balances reliability, cost, and operability. Use this guide when mapping services, data stores, and deployment automation flows.

Layered model

Layer	Components	Notes
Edge	CDN, WAF, rate limits	Cache static assets; protect APIs
Compute	Containers, serverless, VMs	Prefer stateless tiers
Data	SQL, NoSQL, object storage, caches	Define backup and retention
Platform	IAM, secrets, VPC, DNS	Shared across environments

Health and readiness

export function health(): Response {
  return Response.json({
    status: 'ok',
    ts: Date.now(),
    service: 'api',
  });
}

Expose /health and /ready for load balancers and observability checks.

Operational checklist

• Multi-AZ or regional redundancy for critical paths
• SLOs defined before launch; alert on error budget burn
• Run open-source dependencies with pinned versions
• Document runbooks alongside developer docs for SEO-friendly public status pages
