Serverless TTFB & Edge Infrastructure Engineering
Profile the full response path, move suitable work closer to users, and verify the result by region, cache state, and page type.
Engineering Deliverables & Verifiable Outcomes
Fixed-scope, sprint-based implementation plan with transparent deliverables at every milestone.
Mapping origin server latency, analyzing CDN cache hit ratios, and diagnosing SSL handshake delays.
Migrating backend compute to lightweight Vercel Edge / Cloudflare Worker functions with automated cache-tag invalidation.
Deploying Anycast DNS routing, HTTP/3, TLS 1.3 session resumption, and early hints (103 Early Hints).
Automated health checks, zero-downtime canary deployments, and real-time distributed latency monitoring.

When an origin server is located in Frankfurt and a customer browses from New York or Dubai, physical fiber optic distance alone introduces significant latency. Adding traditional monolithic database queries and server rendering pushes TTFB past 1,200ms.
We bring your computation and content directly to the user's nearest edge node.

1. 103 Early Hints & HTTP/3
We send preload headers for critical CSS and fonts before the full HTML payload is finished, allowing the browser to download assets in parallel.
2. Stale-While-Revalidate (SWR) Caching
Where content can be cached safely, stale-while-revalidate can serve a cached response while refreshing it asynchronously. Results vary with cache state, region, payload, and platform.
3. Serverless Auto-Scaling
Managed serverless platforms reduce some infrastructure work but still require capacity planning, observability, security updates, cost controls, and cold-start evaluation for the chosen runtime.
Performance Comparison
| Dimension | Legacy Single-Origin Hosting | AppWebSeo Edge Architecture |
|---|---|---|
| TTFB | Measure by region, page and cache state | Compare the same cohorts before and after |
| DNS / Connection | Capture in RUM and controlled tests | Separate from origin processing time |
| Traffic Spikes | Load-test current bottlenecks | Verify platform limits and degradation behavior |
| Cold Starts | Profile the selected runtime | Report distributions, not a universal zero |

Answers to the most critical architecture, indexing, and investment questions.
TTFB is the time until the browser receives the first byte of the response. It contributes to downstream rendering, but a fast TTFB does not guarantee a fast LCP. Useful targets depend on region, cache state, page type, personalization, and backend work, so we establish them after measuring the actual path.
