AWS vs Azure vs Google Cloud: 9 Real Differences (2026)

Between April and June 2026, businesses spent $143.4 billion renting cloud infrastructure, and most of that money landed with just three companies. If you are choosing one to learn, build on, or recommend at work, the AWS vs Azure vs Google Cloud decision can feel bigger than it should.

This guide breaks it into 9 real differences. Every number comes from Q2 2026 earnings filings, official free-tier pages, or independent market research, including the AI platform changes that most older comparisons still get wrong.

AWS vs Azure vs Google Cloud at a Glance (2026)

Short answer: AWS is the largest and broadest cloud, Azure fits best if your company already runs on Microsoft 365 and Windows, and Google Cloud is the fastest-growing of the three with standout data and AI tools. No single platform wins for everyone. Your current tools, budget, and career goal decide it.

Who Leads the Cloud Market in 2026?

Amazon is still the biggest player, but its lead is shrinking. According to Synergy Research Group, worldwide cloud infrastructure spending grew 43% year over year in Q2 2026, the fastest pace in eight years. Amazon held 28% of that market, Microsoft 20%, and Google 15%.

A year earlier, Amazon was near 30% and Google near 13%. So the gap is closing from both sides, even while all three keep growing.

The Q2 2026 Cloud Scorecard

Here is how the three compare using only their own reported numbers for the April to June 2026 quarter. Microsoft's fiscal year ends June 30, so its "fiscal Q4 2026" covers the same three months.

Microsoft does share one big milestone. In its fiscal 2026 results, CEO Satya Nadella said Azure revenue passed $100 billion for the first time over the full year.

Google's jump is the eye-opener. Its cloud unit nearly doubled revenue in twelve months and more than tripled its operating income. Alphabet credited demand for AI infrastructure and AI solutions.

What the Backlog Numbers Reveal

Revenue shows the present. Backlog shows money customers have already committed for the future.

• Amazon: its Q2 2026 Form 10-Q lists about $496 billion in long-term contract commitments not yet booked as revenue. The same filing describes expanded deals with OpenAI ($100 billion over 8 years) and Anthropic ($100 billion over 10 years).
• Microsoft: commercial remaining performance obligations rose 84% to $678 billion. That figure includes Microsoft 365 and other commercial contracts, not only Azure.

Compute, Storage and Databases: Service Names Mapped

Under the branding, the three clouds offer very similar building blocks. Once you learn one, the core ideas carry over. The table below matches the equivalent services.

A few practical differences matter more than the names:

• AWS has the deepest catalog, so there is usually a managed service for whatever niche job you have.
• Azure links directly with Entra ID (the identity system behind Microsoft 365 sign-ins), which makes it the natural pick for companies already on Microsoft.
• Google Cloud is known for BigQuery, a serverless data warehouse that suits teams doing heavy analytics. Google also created Kubernetes, and GKE remains a favorite for container-heavy teams.

AI and Machine Learning: Bedrock vs Foundry vs Gemini Enterprise

This is the part of the comparison that changed most in 2026, and where many older articles are now out of date.

What Changed in 2026

For years, the simple rule was: want OpenAI models on a big cloud, go to Azure. That rule broke on April 28, 2026. On that date, AWS announced that, for the first time, its customers could reach OpenAI's frontier models inside Amazon Bedrock, starting in limited preview. By September 2026, AWS had announced general availability of newer OpenAI models on Bedrock.

Google made its own big move a week earlier. On April 22, 2026, it introduced the Gemini Enterprise Agent Platform as the evolution of Vertex AI, folding model access, model building, and agent building into one product.

Microsoft also rebranded. What used to be Azure AI Studio, then Azure AI Foundry, is now Microsoft Foundry, according to Microsoft's own documentation.

Behind all this is real money. Synergy Research found that GenAI-specific cloud services grew 165% year over year in Q2 2026.

Which Models Each Cloud Offers

1. 1. Amazon Bedrock: a single API for models from Anthropic (Claude), Meta (Llama), Amazon's own models, and since 2026, OpenAI. AWS also builds its own AI chips, called Trainium.
2. 2. Microsoft Foundry: Microsoft's docs list access to more than 10,000 models from Microsoft, OpenAI, Anthropic, Meta, and others, with built-in governance through Entra ID and Azure Policy.
3. 3. Gemini Enterprise Agent Platform: Google's Gemini and Gemma models plus more than 200 models in Model Garden, including third-party options. Google runs much of its AI on its own TPU chips.

The three main cloud AI platforms in 2026: Amazon Bedrock, Microsoft Foundry and Google's Gemini Enterprise Agent Platform.

Pricing and Free Tiers: Which Cloud Is Cheapest?

Here is the honest answer: none of them is always cheapest. Prices vary by service, region, and how long you commit. A virtual machine that is cheaper on one cloud can cost more there once storage, networking, and data transfer fees are added.

What you can compare fairly is how each one lets you start for free:

• AWS: new customers get up to $200 in credits ($100 at signup, plus up to $100 more for trying key services), valid for up to 6 months. More than 30 services stay free within monthly limits.
• Google Cloud: a $300 welcome credit to use over 90 days, plus 20+ products with always-free monthly allowances.
• Azure: a free trial, then 12 months of free monthly amounts on popular services for new customers, plus 65+ always-free services.

Once you move past free tiers, the bigger savings come from commitment discounts: AWS Savings Plans and Reserved Instances, Azure Reservations and savings plans, and Google Committed Use Discounts. All three offer them.

Waste is the real cost problem. Flexera's 2026 State of the Cloud Report, a survey of 753 cloud decision-makers, found that wasted spend on cloud infrastructure rose to 29%, the first increase in five years.

Global Reach: Regions and Zones Compared

Each provider runs data centers grouped into regions, with separate zones inside each region for backup and uptime.

• AWS: 39 regions and 124 Availability Zones, with 9 regions in North America.
• Google Cloud: 43 regions and 130 zones.
• Azure: 80+ regions and 500+ datacenters worldwide.

Do not compare these counts one to one. Each company defines a "region" a little differently. For US readers, all three have multiple regions across the country, so latency is rarely the deciding factor. What matters more is whether the exact service you need runs in your preferred region. Every provider publishes a products-by-region list, so check it before you build.

Security, Compliance and US Government Cloud

All three clouds use the shared responsibility model. The provider secures the physical data centers and core infrastructure. You secure your accounts, settings, data, and access. Most cloud breaches come from the customer's side, such as open storage buckets or weak passwords, so this split matters. If you are new to the basics, start with this guide on what cyber security actually covers.

For US public-sector work, each provider has a dedicated path:

• AWS GovCloud (US): isolated regions built for US government workloads and regulated industries.
• Azure Government: a separate cloud for US federal, state, and local agencies and their partners.
• Google Cloud Assured Workloads: runs FedRAMP High workloads on Google's public cloud by enforcing US data location and personnel access controls.

Which Cloud Should You Learn for Your Career?

Cloud skills pay well in the US. According to the US Bureau of Labor Statistics, computer network architects earned a median salary of $134,050 in May 2025. Their jobs are projected to grow 8% from 2025 to 2035, and the BLS names the continued expansion of cloud computing as one of the reasons.

Which platform to learn first depends on where you want to work:

• Beginners with no preference: start with AWS. It holds the largest market share, so its skills apply to the widest range of employers.
• People in Microsoft-heavy workplaces: Azure often feels easier. Its service names are plain (Virtual Machines, Blob Storage), and it links directly with the Microsoft 365 accounts your company already uses.
• Data and AI career paths: Google Cloud's BigQuery and Gemini Enterprise Agent Platform line up well with analytics and machine learning roles.

A simple 4-step starter path:

1. 1. Pick one cloud based on your target employer or industry.
2. 2. Earn its entry certification: AWS Certified Cloud Practitioner, Azure Fundamentals (AZ-900), or Google Cloud Digital Leader.
3. 3. Build one small project on the free tier, such as a static website or a basic API, and put it on GitHub.
4. 4. Add the core skills employers want for AI and tech jobs, like Python, Linux, and networking basics.

Multi-Cloud: Why Many Companies Use More Than One

Picking one cloud does not lock most companies in forever. Flexera's 2026 State of the Cloud Report found that 73% of organizations run a hybrid setup that mixes public cloud with private infrastructure.

The 2026 AI deals make mixing even more likely. A company might keep email, identity, and office tools on Microsoft, run its main app on AWS, and send analytics to BigQuery.

Tools that make this easier include Terraform for writing infrastructure as code and Kubernetes for running the same containers on any cloud. Both are core parts of modern DevOps practice, which is why DevOps and cloud skills tend to go together.
