Three Major Cloud Platforms Overview

Before diving into detailed comparisons, let's quickly understand the background and positioning of the three platforms.

Market Share and Development History

AWS is the pioneer of the cloud industry. Since launching S3 and EC2 in 2006, it has built the most complete service ecosystem. Currently with 200+ services, it's the cloud platform with the broadest service range.

Azure caught up quickly, leveraging Microsoft's deep roots in the enterprise market, with particularly high adoption among existing Windows Server, Office 365, and Dynamics users. It has grown fastest in recent years.

GCP has the smallest market share but unique advantages in specific areas—BigQuery data analytics, Kubernetes (GKE), and AI/ML (Vertex AI, Gemini) are industry benchmarks.

Core Advantages of Each Platform

If you're not familiar with AWS services, you can first refer to the AWS Complete Guide.

Compute Services Comparison

Compute is the most fundamental cloud service, and the three platforms' virtual machine services each have their characteristics.

Virtual Machine Service Comparison

Serverless Compute

Comparison Conclusion:

• Choice Diversity: AWS > Azure > GCP
• Price Competitiveness: GCP (Spot) ≈ AWS ≈ Azure
• Serverless: Each has advantages, GCP has highest free tier

Storage Services Comparison

Object storage is the most commonly used cloud storage type and an important revenue source for all three platforms.

Object Storage Comparison

Object Storage Pricing (US East Region, per GB/month)

Pricing Conclusion: Azure and GCP are slightly cheaper for standard storage, but AWS S3 has the most granular storage classes for more precise cost optimization.

Block Storage Comparison

Comparison Conclusion: AWS EBS has the highest performance specs, suitable for I/O-intensive workloads.

Database Services Comparison

Databases are the core of enterprise applications, and all three platforms offer rich managed database services.

Relational Databases

Featured Services:

• AWS Aurora: MySQL/PostgreSQL compatible, 3-5x performance improvement
• Azure SQL: Best native SQL Server support, highest .NET integration
• GCP AlloyDB: PostgreSQL compatible, optimized for analytical workloads

NoSQL Databases

Comparison Conclusion:

• Simple key-value: DynamoDB most intuitive
• Multi-model needs: Cosmos DB most flexible
• Large-scale time-series data: Bigtable is the benchmark

AI/ML Services Comparison

AI is the main battleground for cloud competition in recent years, with all three platforms heavily investing in generative AI.

Generative AI Platforms

Model Pricing Comparison (per million tokens)

Cloud platform resale rates (Bedrock / Azure OpenAI / Vertex AI) may differ from first-party pricing, so check each platform's pricing page.

First-party list prices you can use as a reference (as of 2026-09-30): Claude Sonnet 5.5 (the current Sonnet, released 2026-09-28) is $2/$10; the previous Sonnet 5 is also $2/$10 (Anthropic has cancelled the planned increase to $3/$15); Gemini 3.1 Pro Preview is $2.00/$12.00 (up to 200k context) and $4.00/$18.00 (above 200k); OpenAI gpt-6.1-sol / gpt-6-sol are $2.00/$10.00 (the flagship gpt-6-astra is $10.00/$50.00).

Comparison Conclusion:

• Want Claude: Any of the three (AWS Bedrock, Google Cloud, Microsoft Foundry)
• Want the OpenAI GPT-6 series: Azure OpenAI or AWS Bedrock
• Want Gemini: Choose GCP (Gemini Enterprise Agent Platform, formerly Vertex AI)
• Lowest Cost: all three offer low-cost lightweight models (first-party prices such as gpt-6-luna at $0.10/$0.50 and Gemini 3.5 Flash-Lite at $0.30/$2.50; cloud platform prices are on each platform's pricing page) — compare based on your usage

Machine Learning Platforms

Comparison Conclusion:

• Feature completeness: SageMaker > Azure ML ≈ Vertex AI
• Data analytics integration: Vertex AI (native BigQuery integration)
• Microsoft ecosystem integration: Azure ML

Price Comparison

Price is one of the key factors in choosing a cloud platform, but also the most complex comparison item.

Billing Model Differences

GCP's Unique Advantage: Sustained Use Discount applies automatically without commitment—as long as your VM runs more than 25% of the month, discounts start. This is friendly for teams without prepayment ability.

Same-Spec VM Monthly Cost Comparison

Using a 4 vCPU, 16 GB RAM VM as example (list prices as of 2026-09; AWS/Azure in US East, GCP in us-central1; VM only, excluding disks, 730 hours/month):

Conclusion: On-demand prices are similar across all three, but AWS and Azure have deeper long-term reserved discounts; Spot prices fluctuate on all three, so compare live quotes.

Free Tier Comparison

Conclusion: GCP's permanent free VM is most friendly for long-term learning or small projects; Azure's $200 credit is suitable for short-term trials. AWS changed its free plan in 2025 — new accounts now get credits with a 6-month window instead of the old "750 hours of t2.micro a month for 12 months", while 30+ services stay free within monthly usage limits (AWS Free Tier).

Taiwan Market Support Comparison

For Taiwan enterprises, local support is an important consideration.

Taiwan Data Center Information

Major Difference: AWS (Taipei, ap-east-2) and GCP (Changhua, asia-east1) both operate cloud regions in Taiwan, while Azure does not — a key difference for applications with data residency requirements or latency sensitivity.

Taiwan Partners and Support

Conclusion: All three platforms have considerable support in Taiwan. AWS partner ecosystem is most mature; Azure is most convenient for existing Microsoft customers.

How to Choose a Cloud Platform

After all these comparisons, how do you decide? Here are practical recommendations.

Choose by Industry

Choose by Technical Requirements

Choose by Budget

Multi-Cloud Strategy Considerations

More enterprises are adopting multi-cloud strategies, but this doesn't mean "use everything":

Reasonable Multi-Cloud Strategy:

• Primary workloads on single platform (reduce complexity)
• Specific services on strongest platform (e.g., BigQuery on GCP)
• Disaster recovery on second cloud

Not Recommended Multi-Cloud Strategy:

• Spreading across multiple clouds without clear reasons
• Pretending multi-cloud for pricing negotiation

Seven Dimensions Summary Comparison

FAQ

Q1: Is Highest Market Share Best?

Not necessarily. AWS's highest market share means most mature ecosystem, easiest to find talent, most documentation, but doesn't mean best for every scenario. Choice should be based on your specific needs.

Q2: Can I Switch Cloud Platforms Later?

Yes, but it's expensive. Cloud migration typically takes 6-18 months, with downtime risks and relearning costs. Evaluate carefully before choosing.

Q3: Which Cloud Certification is Most Valuable?

From job market perspective, AWS certification demand is highest, Azure second, GCP third. But this reflects market share, not technical superiority.

Q4: Which Should Startups Choose?

Depends on your tech stack and target market. If using Google technologies (Firebase, Kubernetes), GCP integration is best. If targeting B2B enterprise customers, AWS or Azure compliance certifications are more complete. GCP's free tier is most friendly for startups.

Q5: Which to Choose in the AI Era?

Depends on which model you want to use:

• Want Claude: Any of the three (AWS, GCP, Azure)
• Want the OpenAI GPT-6 series: Choose Azure or AWS
• Want Gemini: Choose GCP

If still uncertain, AWS Bedrock's multi-model support offers most flexibility.

Q6: Are There Special Considerations for Taiwan Enterprises?

Yes. If there are data residency regulatory requirements (like financial industry), both AWS (Taipei) and GCP (Changhua) offer Taiwan regions. If already heavily using Microsoft products (Office 365, Teams), Azure integration will be smoother.

Next Steps

Choosing a cloud platform is a long-term decision. Recommendations:

1. Clearly List Requirements: Necessary features, budget, compliance requirements
2. Do PoC Testing: Use free tier to actually try out
3. Consult Professional Opinions: Find neutral cloud consultants to evaluate
4. Plan Migration Path: Don't rush into full migration
