Question 1

Photos uploaded → use Vision API → delete inappropriate ones → want simplest, cheapest deployment.

❌ GKE
🟩 Cloud Run functions
❌ App Engine
❌ Compute Engine

Explanation:

Cloud Run functions (Cloud Functions) are ideal for:

• Event-driven tasks (triggered when an image is uploaded)

• Very low cost (pay only when executed)

• No servers to manage
  Perfect for Vision API + Cloud Storage triggers.

Question 2

You have Docker containers on Compute Engine and want to reduce cost + simplify container management.

🟩 Migrate the containers to GKE.
❌ Write Terraform scripts
❌ Rewrite apps for Cloud Run functions
❌ Rewrite apps for App Engine standard

Explanation:

GKE:

• Runs Docker containers natively

• Automates scaling & orchestration

• Reduces operational overhead

• Cheaper than running large VM fleets

No need to rewrite apps — just migrate containers.

Question 3

Existing .NET 4 app → requires Windows Server → no code changes.

❌ GKE
❌ Cloud Run functions
❌ App Engine
🟩 Compute Engine

Explanation:

Only Compute Engine supports:

• Windows Server VMs

• Full control over OS

• Legacy apps with no modifications

App Engine, GKE, Cloud Run do NOT support .NET Framework 4 on Windows.
