European challenger bank: PCI DSS at the edge, zero outages in two years

Wed, 08 Apr 2026 00:00:00 +0000

The challenge

A fast-growing European challenger bank had outgrown its initial cloud-native architecture. With customer count tripling year-over-year and increasing scrutiny from financial regulators, the platform needed:

A PCI DSS Level 1 Service Provider ready edge architecture
Sub-200ms TTFB across Europe
A serious answer to DDoS and credential stuffing
Workload-level isolation for cardholder data environments

The existing stack — a single-region cloud provider’s WAF and CDN combination — couldn’t deliver any of these at the required level.

Global retailer: Black Friday-ready in 90 days

Thu, 15 Jan 2026 00:00:00 +0000

The challenge

A top-100 global retailer had spent two years quietly outgrowing its existing CDN deployment. With a major Black Friday campaign 90 days out, the team flagged two problems they couldn’t solve internally:

Catalog cache hit ratio was 71% — and origin egress was scaling alarmingly with traffic
Scraper traffic from competitors had reached an estimated 18% of total catalog requests
Previous peak seasons had required emergency origin scaling and triggered Tier-2 incidents

The platform team needed a 90-day path to confident peak readiness.

Regional airline: cutting search latency in half, globally

Sun, 30 Nov 2025 00:00:00 +0000

The challenge

A regional airline group with operations across three continents was losing competitive ground in metasearch placement — primarily because their search response times were too slow. Internal data showed look-to-book ratio dropping below industry benchmark in three key markets.

The technical root cause was a series of inefficient paths between metasearch partners, the airline’s booking API, and downstream GDS calls. Each hop added latency, and the existing CDN deployment wasn’t optimized for the request patterns.
