Worldwide share looks settled until it is split by geography. Then China turns out to have almost none of the same names on the board, and Europe turns out to have been losing its own.

Lens 1 — developer adoption by region
What this measures. Share of survey respondents who report having worked
with each platform (multi-select — rows do not sum to 100%). It proxies developer mindshare, not
revenue: enterprise spend (where Azure is strongest) is under-represented by developer surveys,
which is itself part of the story. Derivation:
prepare_so_adoption.py;
countries with ≥100 respondents only.
Lens 2 — the two markets that break the pattern
Why the map looks like this
China is structurally closed, not just competitive. Synergy (2024): "western cloud
providers are severely restricted from competing in the Chinese market" — all top-ten providers
in China are Chinese; foreign clouds must operate through local partnerships, which left AWS and
Azure inside a ~20% "others" bucket (Canalys 2021) and AWS at #5 in IaaS with 8.1% (IDC 2023).

Europe lost share through scale, not regulation. European providers tripled revenue
2017–2024 but their home-market share fell 29% → 15% because the market grew ~6x and the US big-3
now invest "~€10 billion every quarter" in European capex — "a game of scale… no European companies
have come close" (Synergy's John Dinsdale). Survivors (SAP, Deutsche Telekom at 2% each, OVHcloud,
Orange) settled into sovereignty/niche roles.
(Synergy 2025)
Outside China, the market is strikingly uniform. The big-3 hold the same ranking in the
US, Europe, APAC-ex-China and the rest of the world (Amazon 32 / Microsoft 23 / Google 12, ex-China,
2024Q2); local champions (Fujitsu/NTT in Japan, Naver/KT in Korea, Telstra in Australia) only reach
the top-6. (Synergy)
The developer data adds texture revenue can't. Azure's adoption gap vs AWS nearly closes
in Germany and the UK (Microsoft's enterprise base), while GCP over-indexes across India, Brazil and
Africa — consistent with Microsoft strength in European enterprises and Google strength with
developer-led, mobile-first markets.
China's growth is now AI-driven and consolidating. Spending re-accelerated to +16% YoY
($11.6B, 2025Q1) on AI demand "despite US export restrictions on advanced semiconductor access" —
the AI cycle is happening on both sides of the wall, with different chips.
