Amazon Web Services provides 200+ cloud services: compute (EC2, EKS, Lambda, Fargate), storage (S3, EBS, EFS), databases (RDS, Aurora, DynamoDB, Redshift), networking (VPC, Transit Gateway, CloudFront), and AI/ML (SageMaker, Bedrock). AWS has the largest market share, the most availability zones, and the broadest service catalog.
Enterprise AWS requires: multi-account strategy (AWS Organizations, SCPs, SSO), networking (VPC design, Transit Gateway, PrivateLink), security (IAM policies, GuardDuty, Security Hub), cost management (Reserved Instances, Savings Plans, Cost Explorer), and the Well-Architected Framework reviews that identify architectural risks.
