AWS vs Google Cloud vs Azure Pricing 2026: Real Cost Comparison

Cloud bills are the fastest-growing line item for most software companies — and the "cheapest" provider depends heavily on your workload. AWS has the most services but charges premium for data egress. Google Cloud is often 20–30% cheaper on compute. Azure wins when you're already in the Microsoft ecosystem. Here's the real cost breakdown for 2026.

Compute Pricing: The Biggest Cost Driver

Compute is usually 40–60% of a cloud bill. Here's a direct comparison of equivalent general-purpose instance types in US East regions (2026 on-demand pricing):

Reserved/Committed Use Discounts

On-demand pricing is rarely what you pay at scale. All three providers offer deep discounts for commitment:

Real Cost Models: What Does Each Cloud Actually Cost?

Model 1: Early-Stage Startup (5 engineers, simple web app)

Model 2: Growth-Stage SaaS (20 engineers, 100K MAU)

Model 3: Enterprise (200 engineers, data-heavy workload)

Data Transfer Costs: The Most Underestimated Expense

Managed Database Pricing

AI / Machine Learning Pricing

ML infrastructure is the fastest-growing cloud cost center in 2026. All three providers charge for GPU instances, but the pricing models differ significantly:

When to Choose Each Cloud

Hidden Costs You Won't See in the Calculator

1. Support Plans

2. Data Transfer Within Clusters

AWS charges $0.01/GB for traffic between EC2 instances in the same region but different availability zones. For high-traffic microservices architectures, this adds up. GCP and Azure are similar. Design your architecture to co-locate services in the same AZ when possible.

3. NAT Gateway Fees (AWS)

AWS NAT Gateways cost $0.045/hr ($32/mo each) plus $0.045/GB of processed data. A high-traffic system in a private VPC can spend $500–2,000/month just on NAT Gateway fees. GCP's Cloud NAT is significantly cheaper ($0.002/GB after 20 GB free).

4. Load Balancer Costs

AWS Application Load Balancer: $0.008/LCU-hour + $0.016/hr fixed = ~$12/mo minimum, plus usage. GCP Load Balancing: $0.008/hr per forwarding rule + data processing. Azure: $0.008/hr + $0.005/GB. Similar at low traffic, but scales differently at high request volumes.

5. Egress Between Regions

Moving data between regions for disaster recovery or global distribution costs $0.02/GB on AWS and Azure. GCP charges $0.01/GB for inter-region within the US. Multi-region architectures can add $1,000–10,000/month to bills at scale.

Cost Optimization Strategies That Work

For AWS:

• Compute Savings Plans — Buy 1-year or 3-year compute commitments. 40–60% savings. More flexible than Reserved Instances.
• Spot Instances — 70–90% off on-demand for fault-tolerant workloads (batch jobs, dev/test)
• S3 Intelligent-Tiering — Automatically moves data between tiers. Eliminates manual lifecycle management.
• RDS Reserved Instances — 30–40% off for database instances you know you'll run for 1+ years
• Cost Explorer + Trusted Advisor — AWS's free tools surface idle resources and unused reservations

For GCP:

• Committed Use Discounts — 37–55% off for 1–3 year resource commitments
• Sustained Use Discounts — Automatic 20–30% discount after running 25%+ of month — no action needed
• Preemptible VMs — 80% off for batch/fault-tolerant workloads
• BigQuery slot commitments — Flat-rate pricing for predictable query workloads instead of per-TB pricing
• Custom machine types — Specify exact CPU/memory to avoid paying for capacity you don't use

For Azure:

• Azure Hybrid Benefit — If you have Windows Server or SQL Server licenses, apply them to Azure VMs. 30–40% additional savings.
• Reserved VM Instances — 36–52% off for 1–3 year commitments
• Spot VMs — 60–80% off for interruptible workloads
• Azure Cost Management + Budgets — Set spend limits and alerts before bills spiral
• Dev/Test pricing — Significant discounts for non-production environments with Visual Studio subscriptions

Price History: When Did Each Provider Raise Prices?

FAQ

Is AWS more expensive than GCP?

For pure compute and storage, GCP is typically 15–25% cheaper than AWS on equivalent workloads. But AWS has more mature services in some areas, and the total cost depends heavily on your specific architecture. Egress fees are similar across all providers. AWS Savings Plans can close the gap significantly if you commit.

Is Azure cheaper if we use Office 365?

Not necessarily, unless you have existing Windows Server or SQL Server licenses. Azure Hybrid Benefit can save 30–40% on VMs and databases if you have qualifying Microsoft licenses. Without that, Azure and AWS are priced very similarly for most workloads.

Can I use multiple clouds to reduce costs?

Multi-cloud reduces vendor lock-in but adds operational complexity and typically increases costs. Egress between clouds is expensive ($0.08–0.09/GB). The cost savings rarely outweigh the management overhead unless you have a specific use case (e.g., BigQuery for analytics on GCP + workloads on AWS).

How much can I save by switching clouds?

Migrations are expensive (typically 6–18 months of engineering time). The actual compute/storage savings (10–25%) often take 2–3 years to recoup migration costs. Optimize your current cloud first before switching.

What's the actual cheapest cloud for a startup?

For most early-stage startups, GCP or AWS are similar. GCP's always-free tier is slightly more generous, and sustained use discounts help keep costs down without requiring reservations. AWS has more startup credits available (AWS Activate up to $100K). The decision usually comes down to your team's expertise and which services you need.
