Case Studies

Three anonymized stories where we moved high‑stakes edge workloads with zero downtime — across 200‑500+ domains — in weeks, not quarters.

B2C • Consumer Brand

200+

Subdomains

1.5 mo

Duration

Downtime

200+ subdomains from Akamai → AWS in 1.5 months — zero downtime

Context

High‑traffic B2C brand (millions of daily requests) across India & SEA
200+ subdomains with varied cache keys, signed URLs, device/CDN behaviors
Heavy Akamai feature usage; rising egress & CDN costs

Problem

Performance variability in key regions; limited IaC; vendor lock‑in risk
Rules drift and inconsistent cache policies across subdomains

Solution

Parity map Akamai behaviors → CloudFront (origins, cache keys, headers)
Edge function rewrite: EdgeWorkers → Lambda@Edge
WAF: COUNT → tune → BLOCK; bot mgmt mapping; rate limits
Cache warming, RUM baseline; blue/green DNS & real‑time dashboards

Outcome

Cutover with 0 downtime (windows < 30min)
35% egress/CDN cost reduction
Cache hit ratio +12% (to 98–99%)
Delivery time p95 improved by 14% in India

Migration timeline

1.
Assess
Inventory, configs, traffic profile, risks
2.
Plan
Akamai→AWS parity map, rollback paths, KPIs
3.
Simulate
Lab + shadow traffic; WAF COUNT mode
4.
Dual‑Run
Mirrored paths, compare logs/latency, tune rules
5.
Cutover
Cohorts; time‑boxed windows; live dashboards
6.
Optimize
Cache keys, TLS, Brotli/GZIP, cost tuning

Want a risk‑free migration plan for your stack?

We’ll map parity, simulate with shadow traffic, then dual‑run before cutover.

Media • News Agency

300+

Domains

1 mo

Duration

Downtime

300+ domains from Cloudflare → AWS in 1 month — uninterrupted publishing

Context

National news group with 24/7 publishing and breaking‑news surges
300+ domains including regional editions and vanity domains

Problem

WAF false positives impacting editorial tools under load
Cache drift and inconsistent TTLs; compliance audit pressure

Solution

COUNT‑first WAF rollout; tune FP; normalize managed+custom rules
Terraform for reproducible CDN/WAF; Log pipelines (Kinesis/Firehose)
Staged DNS steering with health checks; synthetic + RUM monitoring

Outcome

All domains migrated in 30 days with 0 disruption
API error rate ↓ 22% after FP tuning; editorial tools stable
Faster regional delivery (p95 −11%)

False positive rate (index)

Latency p95 (index)

Migration timeline

1.
Assess
Inventory, traffic hot paths, newsroom SLOs
2.
Plan
Cloudflare→AWS parity; FP reduction SLOs
3.
Simulate
Shadow traffic; COUNT mode; dashboards
4.
Dual‑Run
Mirror + compare; tune bot mgmt/rate‑limits
5.
Cutover
Staged by edition; off‑hours windows
6.
Optimize
Cost & cache policies; audit artefacts

B2B • Global SaaS

500+

Domains

phased

Duration

Downtime

500+ domains from Akamai → AWS — global rollout, zero downtime

Context

Enterprise SaaS with partner SLAs and multi‑region user base
500+ domains, heavy API & image traffic

Problem

Complex Akamai rules and tokenization; visibility gaps
Latency sensitivity and strict error budgets across regions

Solution

IaC parity (behaviors, signed URLs/tokens); workers rewrite
Active‑active design; DNS steering; health checks
Synthetic+RUM baselines; incident playbooks; blue/green DNS

Outcome

Zero‑downtime cutovers across regions
Cache hit > 99%; p95 latency −18% in EMEA/APAC
Operational handover with Terraform + dashboards

Latency p95 (index)

Cache hit ratio

Migration timeline

1.
Assess
Config inventory; partner SLA review
2.
Plan
Parity map & rollback; region cohorts
3.
Simulate
Shadow traffic; WAF COUNT; failover drills
4.
Dual‑Run
