A practical comparison of services, global datacenters and future plans (Oct 29, 2025)
Cloud computing is now the backbone of modern apps, AI, and enterprise IT. The three largest public-cloud providers — Microsoft Azure, Amazon Web Services (AWS), and Google Cloud Platform (GCP) — compete aggressively on features, price, regional coverage, enterprise integrations and AI capabilities. Below I compare them in everyday terms, summarize their global datacenter footprints, list noteworthy upcoming expansions and projects, and finish with practical recommendations so you can choose the best cloud for your needs.
Quick TL;DR
-
AWS — market leader with the broadest service catalog and the deepest operational maturity. Best for organizations needing a massive service ecosystem, global reach, and advanced infrastructure primitives. Amazon Web Services, Inc.+1
-
Azure — strongest for enterprises (Windows/.NET/Office/Active Directory) and hybrid scenarios; claims the largest regional footprint and the most physical datacenter sites. Great when close Microsoft integration and data residency are priorities. Microsoft Azure+1

Global datacenter footprints — who has more physical datacenters?
Important note: Cloud providers expose their regions/zones publicly, but the exact count of physical buildings (every hall/campus) is proprietary and fluid. Providers report region & AZ counts; Azure additionally publishes a “datacenter site” count. Below are the authoritative, provider-published figures and reputable summaries as of Oct 29, 2025.
-
AWS (Amazon Web Services)
AWS states the cloud spans 120 Availability Zones within 38 geographic Regions, with additional Regions and AZs announced/forthcoming. AWS also publishes Local Zones, Wavelength zones and a global edge footprint. This AZ + region model is how AWS expresses coverage, and AWS tends to have the largest number of AZs distributed across regions. Amazon Web Services, Inc.+1 -
Microsoft Azure
Microsoft advertises 70+ Azure regions and 400+ physical datacenter facilities (their published metric) — Azure explicitly highlights having “more regions than any other cloud provider” and a very high count of physical datacenter sites. For customers needing specific datacenter locations, Microsoft provides an interactive datacenter map. Microsoft Azure+1 -
Google Cloud (GCP)
Google Cloud’s published materials (Google Cloud Next 2025 recap and infrastructure pages) note about 42 regions (40+ regions) and roughly ~120–130 zones / availability areas depending on the source and exact date; GCP has been expanding into Sweden, South Africa, Mexico and is rolling out further regions (Kuwait, Malaysia, Thailand etc.). GCP highlights its global private network of subsea and terrestrial fiber as a differentiator. Google Cloud+1
Short summary (by the numbers, provider claims, Oct 29, 2025):
-
Azure — 70+ regions and 400+ datacenter sites (largest count of datacenter facilities by their claim). Microsoft Azure
-
AWS — 38 regions and 120 AZs (largest AZ count; many Local Zones & edge PoPs). Amazon Web Services, Inc.
-
Google Cloud — ~42 regions and ~120–130 zones/PoPs (rapid expansion; strong backbone). Google Cloud+1
(If your blog reader wants a country-by-country list or an interactive map, the providers’ official region pages and “datacenter explorer” tools are the authoritative sources — see the provider pages cited below.)
Notable recent and upcoming projects / investments (what’s next)
AWS — expanding regions and AI infrastructure
-
New regions announced — AWS announced plans for new Regions including Chile and the Kingdom of Saudi Arabia, plus other sovereign cloud regions, and has multiple AZs in planning. The Chile Region is targeted for service by end-2026 and is explicitly positioned to support generative AI workloads locally. Amazon Web Services, Inc.+1
-
Continued investment in edge, local zones and specialized hardware for machine learning and inference; AWS continues to extend services into regulated and sovereign environments. Amazon Web Services, Inc.
Microsoft Azure — enterprise, hybrid & AI datacenters
-
70+ regions, 400+ datacenters and ongoing regional expansion (new datacenters in parts of Asia and Europe). Azure also announced multi-billion investments in AI/cloud infrastructure in European countries and new regions in Asia (Malaysia, Indonesia; new regions in India & Taiwan planned). Microsoft emphasizes hybrid solutions (Azure Arc/Stack) and large AI datacenters for enterprise workloads. Microsoft Azure+2Microsoft Azure+2

-
Google Cloud Next 2025 introduced numerous AI and infrastructure announcements, including new TPU hardware (Ironwood generation) and a major push to expand AI infrastructure globally (new regions and large AI datacenter investments such as multi-billion EUR investments announced in Belgium for AI infrastructure). GCP’s roadmap focuses heavily on data/AI performance and managed AI services. blog.google+1
How to choose — which cloud is best?
There’s no single “best” cloud for everyone. The right choice depends on requirements. Here are practical selection rules:
-
If you need the deepest service catalog + global operational maturity → choose AWS.
Use case: large-scale SaaS with diverse needs (databases, streaming, analytics, edge, IoT), cross-region deployments and a need for very specific services. Amazon Web Services, Inc. -
If you’re an enterprise heavily invested in Microsoft tech or require hybrid on-prem + cloud → choose Azure.
Use case: Windows/SQL Server/.NET, Active Directory, Microsoft 365 integrations, or strict data residency in many global regions. Azure’s region count and datacenter footprint are attractive where locality/residency matters. Microsoft Azure -
If your project is AI/data-centric (ML, BigQuery, TPU, low-latency network) → choose Google Cloud.
Use case: ML model training/inference at scale, data analytics-first products, or when you want Google’s networking and managed AI services (BigQuery, Vertex AI, TPUs). blog.google -
Hybrid & multi-cloud strategy: Many enterprises adopt multi-cloud to avoid vendor lock-in and to place workloads where they’re strongest (e.g., data pipelines on GCP, enterprise apps on Azure, niche services on AWS). Tools like Anthos, Azure Arc, and Terraform help manage multi-cloud deployments. Google Cloud+1
