Buying Guide
AWS vs. Azure vs. Google Cloud
All three are full-scale cloud infrastructure providers capable of running almost any workload. Pricing and specific service names shift too often to compare meaningfully — the real decision driver is which ecosystem you're already standardized on and what that ecosystem gives you natively.
Choose AWS — No strong existing ecosystem pull toward Microsoft or Google, and you want the broadest service catalog and the largest hiring pool of engineers who already know the platform.
Choose Microsoft Azure — Already running on Microsoft 365, Dynamics, or Active Directory — the native integration meaningfully reduces both cost and complexity over bolting a different cloud on top.
Choose Google Cloud — Already standardized on Google Workspace, or building AI-heavy products where native Gemini/Google ML integration is a real, ongoing advantage.
| Ecosystem fit | Azure integrates most natively with an existing Microsoft stack (365, Dynamics, Active Directory); GCP integrates most natively with Google Workspace and Google's own AI/ML tooling; AWS has no single 'home ecosystem' but the broadest overall service catalog and longest track record. |
| Enterprise identity | A business already running on Active Directory generally finds Azure's identity integration (Entra ID) the path of least resistance; AWS and GCP both support enterprise identity federation well, but as an add-on rather than a native extension of an existing directory. |
| AI/ML native tooling | GCP has the most native integration with Google's own models (Gemini) and data tooling; AWS and Azure both offer broad multi-provider AI services rather than being tied to one model family. |
| Switching cost once committed | All three make it easy to start and progressively harder to leave as you adopt provider-specific managed services — the switching cost is a function of how deep you go, not the provider you pick. |
Cost implications
List pricing across all three is close enough, and changes often enough, that comparing published rates is rarely the deciding factor — actual cost depends far more on architecture choices (which managed services you adopt, how much you optimize for your specific usage pattern) than on which provider's base rate is nominally lower this quarter.
Migration considerations
Moving between cloud providers later is a real, non-trivial project — the deeper you've adopted a specific provider's managed services (not just compute/storage, but their specific databases, queues, and AI tooling), the more that migration looks like a partial rebuild rather than a redeploy.
Hidden tradeoffs
- — The 'best' provider on paper matters less than which one your team already has real operational depth in — unfamiliarity costs more in the first year than most provider-to-provider differences do.
- — Multi-cloud (using more than one deliberately) is sometimes framed as reducing lock-in risk, but it also multiplies the operational complexity and expertise required — a real cost, not a free hedge.
Common mistakes
- — Choosing a cloud provider based on a benchmark or pricing comparison that will be outdated within months — all three providers change pricing and service names too often for a fixed comparison to stay accurate.
- — Ignoring existing ecosystem fit (an established Microsoft or Google shop) in favor of whichever provider a previous project happened to use.
- — Underestimating switching cost by choosing based on initial setup ease rather than what happens after two years of adopting provider-specific managed services.
When to choose neither
A small workload with modest, predictable needs sometimes fits a simpler platform-as-a-service provider better than a full hyperscale cloud — not every project needs AWS/Azure/GCP-level breadth.
Decision checklist
- □What existing ecosystem (Microsoft, Google, neither) does your organization already run on?
- □Does your workload have a specific, named requirement only one provider serves well (e.g. deep Gemini integration, deep Active Directory integration)?
- □Does your team already have real operational depth in one of the three, and is retraining onto a different one actually worth it?
Bottom line
Treat this as an ecosystem-fit decision, not a price comparison — published rates shift too often to be the deciding factor, and existing ecosystem integration plus your team's real operational depth matter more than which provider's homepage looks most impressive this year.
FAQs
Which cloud provider is cheapest?
Whichever answer we gave here would be stale within months — all three providers adjust pricing and service structures often enough that a fixed comparison isn't trustworthy. Actual cost depends far more on your specific architecture and usage pattern than on nominal list-price differences between providers.
