Cloud service models (who manages what)
IaaS (e.g. EC2):        you manage OS, runtime, app; provider manages hardware
PaaS (e.g. Elastic Beanstalk): you manage app and data; provider manages platform
SaaS (e.g. email suites):  you just use the software
Shared responsibility: the provider secures the cloud; you secure what you put in it

aws --version
aws configure                       # access key, secret, region (e.g. ap-south-1), output
aws sts get-caller-identity          # which account and user am I?
aws ec2 describe-regions --query "Regions[].RegionName" --output text
aws s3 ls                           # list buckets

Before the course, can I...
☐ Use basic Linux commands (ls, cd, cp, chmod, ssh)?
☐ Explain an IP address, DNS and a port?
☐ Follow written technical instructions carefully?
☐ Commit 8-10 hours a week to labs and revision?
Empty boxes → ask about preparation material.

ssh -i my-key.pem ec2-user@<public-ip>   # connect to a cloud VM
sudo dnf update -y                      # Amazon Linux 2023 package update
sudo dnf install -y nginx
sudo systemctl enable --now nginx
curl -I http://localhost
sudo tail -n 20 /var/log/nginx/access.log

# lambda_function.py — returns a simple JSON response via API Gateway

    name = (event.get("queryStringParameters") or {}).get("name", "learner")
    return {

        "headers": {"Content-Type": "application/json"},
        "body": json.dumps({"message": f"Hello, {name}"}),
    }

☐ What modules are in the current cloud syllabus?
☐ Which platform is the main focus (AWS, Azure, both)?
☐ How many hours are hands-on labs?
☐ Do labs use my own account or a sandbox? How are costs handled?
☐ Which projects will I complete and keep?
☐ Is certification preparation included? Which exams?
☐ Batch timings, current fees and placement support details?
