Aws

AWS is the most feature-complete cloud provider with the widest service breadth and most mature ecosystem. It's the default choice for startups and enterprises that want the most tooling options and largest talent pool. However, 'best' depends on use case: Azure is better for Microsoft-first enterprises (Active Directory, Office 365 integration), Google Cloud is better for data analytics (BigQuery) and Kubernetes (GKE). AWS's complexity and pricing opacity can be costly without careful governance.

AWS pricing is highly variable by service and usage. Common reference points: EC2 t3.medium (2 vCPU, 4GB RAM) costs ~$30/month on-demand, ~$14/month reserved 1-year. S3 storage is $0.023/GB/month. Lambda is free for 1M requests/month, then $0.20 per million. RDS MySQL db.t3.medium is ~$50/month. Data egress is $0.09/GB after 100GB/month free. Most teams spend $200–5,000/month depending on workload. Use the AWS Cost Calculator to estimate before committing.

For startups: AWS has the largest ecosystem, most documentation, and widest talent pool — it's the safest default. For enterprises already on Microsoft 365/Active Directory: Azure integrates more naturally and often has enterprise agreement pricing advantages. For data science and analytics teams: Google Cloud's BigQuery and Vertex AI are best-in-class. For Kubernetes-heavy workloads: GKE (Google Cloud) is considered most mature. Many large organizations use multi-cloud strategies, often with AWS as the primary platform.
