Lab 9 – Serverless Functions

Learning Outcomes

• Create a simple serverless function in AWS or GCP.
• Trigger it via HTTP and inspect the response.
• Compare the serverless model with running containers or VMs.

Tasks

1. Choose one platform:
   • AWS Lambda with API Gateway
   • Google Cloud Functions
2. Implement a small HTTP function that returns JSON, e.g.:

   {"message":"Hello from serverless"}

3. Deploy the function and invoke it from your browser or using curl. Note the URL and the response body.
4. In your notes, compare this function to the shared portal at http://50.116.28.213:31380 in terms of:
   • Who manages scaling
   • How you pay (per request vs. per hour)
   • Deployment steps
