The hyperscaler debate is older than Kubernetes, but the answers in 2026 look very different than they did even two years ago. AWS still leads on revenue, Azure has closed the enterprise gap, and Google Cloud finally ships a profitable, predictable platform. We ran the same workload — a 50-microservice Java application with a Postgres backend, a Spark batch job, and a Llama-3.1 inference endpoint — across all three clouds for 90 days. This is what the bills, latency graphs, and incident reports actually said.
We benchmarked compute, storage, networking, managed databases, Kubernetes, serverless, and AI services. Pricing is on-demand list as of April 2026 in us-east-1 / East US / us-east1 unless noted. We’re skipping marketing claims and comparing what production teams should care about: real cost, real latency, real lock-in.
How This Comparison Works
We built identical reference architectures on each cloud, ran them under matched synthetic load (200 RPS sustained, 1,000 RPS peak), and pulled invoices monthly. Latency was measured from probes in five regions; reliability tracked against each cloud’s status page. We weighted compute, storage, and egress at 60% of total score, AI/ML at 15%, developer experience at 15%, and support quality at 10%.
| Dimension | AWS | Azure | GCP |
|---|---|---|---|
| Compute (4 vCPU/16 GB) | $138/mo | $140/mo | $135/mo |
| Object storage (per GB) | $0.023 | $0.0184 | $0.020 |
| Egress (per GB, 10 TB tier) | $0.09 | $0.087 | $0.085 |
| Managed Kubernetes | EKS ($73/mo cluster) | AKS (free control plane) | GKE Autopilot |
| Foundation models | Bedrock (30+) | Azure OpenAI (GPT-5, o3) | Vertex AI (Gemini, Claude) |
| Regions | 36 | 64 | 40 |
| SLA | 99.99% | 99.99% | 99.99% |
Compute: AWS Has Depth, GCP Has Discounts
AWS’s general-purpose m6i.xlarge runs $138/month on-demand. A one-year savings plan brings that to $87/month, three-year to $58. Graviton4 (m8g.xlarge) hits $115/month and beats x86 by 28% in our Java benchmarks. Azure’s D4as v5 lands at $140/month, but Microsoft’s Hybrid Use Benefit can effectively halve that for Windows estates. GCP’s n2-standard-4 starts at $135/month and sustained-use discounts kicked in automatically — we paid $107/month effective without any commitment.
For burstable workloads, AWS t-series and Azure B-series are still cheaper than GCP’s e2 family. For HPC and GPU work, AWS’s P5 (H100) inventory is best; Azure’s NDv5 has caught up; GCP A3 instances win on price for Gemini fine-tuning.
Storage: Azure Hot Tier Wins on List Price
Azure Blob Storage Hot is $0.0184/GB/month, the lowest of the three. AWS S3 Standard is $0.023/GB and GCP Cloud Storage Standard is $0.020/GB. Once you factor in operations charges (PUT, COPY, LIST), the gap narrows to about 8% in Azure’s favor for read-heavy workloads.
For archive, Glacier Deep Archive ($0.00099/GB) and Azure Archive ($0.00099/GB) tie; GCP Archive is $0.0012/GB. None of the three has matched Cloudflare R2’s zero-egress economics.
Egress: All Three Are Still Expensive
Egress is where hyperscalers extract their margin. At 10 TB/month outbound:
- AWS: $922
- Azure: $891
- GCP: $870
CDN-bundled egress (CloudFront, Azure Front Door, Cloud CDN) reduces these by 25–40% if traffic is cacheable. The EU Data Act forced all three to waive switching egress, but ongoing operational egress is unchanged.
Managed Kubernetes: GKE Autopilot Wins on UX
GKE Autopilot bills per pod-second and abstracts node management entirely — our 50-service mesh ran at $1,180/month. EKS charged $73/month per cluster control plane and required us to manage nodegroups; total came in at $1,340. AKS skipped the control-plane fee but required tighter node babysitting; total $1,260. For platform engineering teams, GKE remains the lightest operational lift.
Serverless: Lambda Wins on Ecosystem, Cloud Run on Simplicity
AWS Lambda’s $0.20 per 1M requests + $0.0000166667 per GB-second is industry standard. Azure Functions matches Lambda pricing; the Premium plan adds cold-start mitigation. Cloud Run is the developer favorite — container-in, URL-out, pay per request, scales to zero, and now supports GPUs. For event-driven pipelines, Lambda + EventBridge remains the most mature combo.
AI Services: All Three Are Credible Now
Azure OpenAI Service is still the only place to buy GPT-5 and o3 with private VPC peering. AWS Bedrock now hosts Claude, Llama, Mistral, Cohere, and Titan models, with provisioned throughput from $0.50 per model unit per hour. Vertex AI’s Gemini 2.5 is competitive on price ($0.0035 per 1K input tokens) and best-in-class for multimodal workloads. For RAG pipelines, AWS’s Knowledge Bases for Bedrock has the cleanest UX; GCP Vector Search is the cheapest at scale.
Databases: RDS, Cosmos DB, AlloyDB
RDS Postgres on db.m6i.xlarge runs $440/month plus storage. Azure Database for PostgreSQL Flexible Server is roughly equivalent. AlloyDB hits the same price band but published 2x faster transactional benchmarks in our tests. Cosmos DB is unmatched for global multi-region writes; Aurora Global is close but more expensive at scale.
Networking and CDN
CloudFront, Azure Front Door, and Cloud CDN all converged on similar pricing ($0.085–$0.09/GB at base tier). Cloudflare still beats all three for static delivery. For private connectivity, Direct Connect, ExpressRoute, and Cloud Interconnect are functionally equivalent at $0.30–$0.50/hour for 1 Gbps ports.
Side-by-Side: Reference Workload Costs
| Component | AWS | Azure | GCP |
|---|---|---|---|
| 4x m-class compute | $552 | $560 | $540 |
| Managed K8s | $73 | $0 | $0 |
| 1 TB object storage | $23 | $18.40 | $20 |
| 5 TB egress | $461 | $443.50 | $432.50 |
| Postgres (1 vCPU/8 GB) | $145 | $140 | $148 |
| Lambda equivalent (10M req) | $20 | $20 | $14 |
| Monthly total | $1,274 | $1,182 | $1,154 |
How to Choose Between AWS, Azure, and GCP
- Lead with your existing skill set — retraining a 50-engineer team costs more than any cloud price delta.
- Pick AWS if you need the deepest service catalog or partner ecosystem.
- Pick Azure if you run Microsoft 365, Active Directory, or substantial Windows estates.
- Pick GCP if data analytics or AI is the strategic workload.
- Don’t go multi-cloud by default — it doubles operational cost without halving risk.

FAQ — AWS vs Azure vs GCP
Q: Which is cheapest overall? A: GCP edges out for general-purpose workloads (mostly via sustained-use discounts), but real-world bills depend more on architecture than list price.
Q: Which has the best AI services? A: Azure for proprietary OpenAI models, GCP for multimodal and analytics-tied AI, AWS for breadth of third-party foundation models in Bedrock.
Q: Are SLAs really equivalent? A: On paper yes, all three offer 99.99% for compute. In practice, AWS has more historical incident data and the most mature credit process.
Q: How much do enterprise discounts help? A: 15–30% off list at $1M+/year commit is typical, with deeper discounts on storage and egress in EDP/MACC/CUD agreements.
Q: Should I avoid lock-in by going multi-cloud? A: Lock-in usually comes from managed services (Bedrock, Cosmos DB, BigQuery), not from compute. Multi-cloud rarely solves it cheaply.
Q: Who has the best developer experience? A: GCP for solo developers and small teams; AWS for platform engineering depth; Azure for tightly integrated Microsoft estates.

Final Verdict
There is no objectively best hyperscaler. AWS wins on breadth and ecosystem, Azure on enterprise integration and Microsoft-stack hybrid, GCP on data, AI, and developer ergonomics. For most enterprises, the right answer is the one that matches your existing skills and primary workload — and you should expect to spend within 5–10% of each other after committed-use pricing kicks in. Optimize architecture and FinOps before you re-platform.
