AWS, Google Cloud Platform (GCP), and Azure are the three major cloud providers. AWS dominates market share with 200+ services. GCP excels in data science and machine learning. Azure integrates deeply with Microsoft enterprise software. Most enterprise companies use AWS; data science teams prefer GCP; Microsoft-heavy organizations use Azure. Many large companies use all three (multi-cloud). Note: This comparison focuses on AWS vs GCP in left/right format, with Azure mentioned in the comparison rows.
AWS vs GCP vs Azure
Side-by-Side Comparison
| Aspect | AWS | GCP |
|---|---|---|
| Market Position | Market leader (>32% market share). Most services (200+). Widest adoption. Most mature. | Strong second (10-11% market share). Focus on quality over quantity. Rapidly growing. Azure also strong (23%) for enterprise. |
| ML & Data Science | SageMaker (good but newer). Jupyter notebooks, training pipelines. Strong but not native focus. | BigQuery + Vertex AI (excellent). TensorFlow native support (Google created TensorFlow). ML experts prefer GCP. |
| Databases | RDS (MySQL, PostgreSQL, Oracle), DynamoDB (NoSQL), RedShift (data warehouse). Comprehensive. | Cloud SQL (MySQL, PostgreSQL), Firestore (NoSQL), BigQuery (warehouse). Simpler options, fewer choices. Azure has Cosmos DB. |
| Pricing | Complex pricing model. Reserved instances, spot instances, on-demand. Needs careful calculation. | Simpler pricing. Pay-per-use, sustained discounts automatic. Easier to predict costs. Azure similar but more complex. |
| Container & Kubernetes | ECS (proprietary), EKS (managed Kubernetes). ECS easier for AWS-only shops. Azure has AKS. | GKE (managed Kubernetes). Built on Google's Kubernetes expertise. Easiest for pure K8s. |
| Enterprise Integration | Good enterprise support. Some Microsoft integration but not native. Azure better for Microsoft shops. | Less native Microsoft integration. Good for pure-cloud companies. Azure dominates Office 365/AD integration. |
| Global Reach | Most regions globally (30+). Most mature global infrastructure. Best for global distribution. | Good global reach (40+ regions). Very fast growth in infrastructure. Azure also comprehensive. |
| Indian Tech Usage | AWS dominates Indian tech. Flipkart, PharmEasy, most startups on AWS. Largest installed base. | Growing in Indian startups. Some data-heavy startups prefer GCP. ISRO uses Google Cloud. |

Verdict
Verdict: AWS is the safe default choice (most services, most hiring, most expertise). GCP is superior for data science and machine learning. Azure for Microsoft-heavy enterprises. For new projects, AWS remains the standard choice in India. Learn AWS first (easiest to find jobs); add GCP if data science interests you. Most large organizations eventually use all three (multi-cloud strategy) to avoid vendor lock-in.
