Quick Answer
Compute VMs: EC2 / Azure VM / Compute Engine. Object storage: S3 / Blob Storage / Cloud Storage. Managed Kubernetes: EKS / AKS / GKE. Serverless: Lambda / Azure Functions / Cloud Functions.
Detailed Answer
The big-three offer near-equivalent primitives under different names. Compute: EC2 ≈ Azure VM ≈ Compute Engine. Object storage: S3 ≈ Blob ≈ Cloud Storage. Block: EBS ≈ Managed Disks ≈ Persistent Disk. SQL: RDS ≈ Azure SQL ≈ Cloud SQL. K8s: EKS ≈ AKS ≈ GKE. Registry: ECR ≈ ACR ≈ Artifact Registry. Knowing the mapping lets you translate architectures across clouds in interviews.

Interview Tip
Have the EC2/VM/Compute Engine, S3/Blob/Cloud Storage, EKS/AKS/GKE triads memorized — they come up constantly.
