About this page

GCP interviews mirror the other clouds but with Google's product names. This module is an elevation arc: core services first (Compute Engine, VPC), then compute and deployment (GKE, Cloud Run, Cloud Functions), storage and data (GCS, Cloud SQL, Spanner), messaging (Pub/Sub), security and IAM, and observability (Cloud Monitoring, Logging).

AWS, Cloud & Cloud-Native Architecture Interview Questions

AWS interviews test whether you can pick the right managed service and wire it to a Spring app. This module is an elevation arc: it opens with the core services (EC2, VPC, the primitives), then containers (ECS/Fargate — the modern deploy unit), then S3, IAM, and RDS (the services every backend touches). Messaging (SNS/SQS/Kinesis) and serverless (Lambda) follow at the applied tier, then the comparison canon and scenario-based architecture questions.
