The Cloud Essential Knowledge Badge Assessment evaluates fundamental knowledge of cloud computing, covering essential topics across platforms like AWS, Google Cloud, and Microsoft Azure. Below are the key areas typically addressed in the exam, along with practical commands and steps to reinforce your understanding.
You Should Know:
1. Basic Cloud Concepts
- What is Cloud Computing?
Cloud computing delivers computing services over the internet, including storage, processing, and networking. - Command to check cloud service status (AWS):
aws ec2 describe-instances --query 'Reservations[<em>].Instances[</em>].State.Name' --output text
- Command to list Google Cloud resources:
gcloud compute instances list
-
Cloud Service Models:
- IaaS (Infrastructure as a Service):
Example: AWS EC2, Google Compute Engine.
- Launch an EC2 instance (AWS):
aws ec2 run-instances --image-id ami-0abcdef1234567890 --instance-type t2.micro --key-name MyKeyPair
- PaaS (Platform as a Service):
Example: Google App Engine, AWS Elastic Beanstalk.
- SaaS (Software as a Service):
Example: Google Workspace, Microsoft 365.
- Cloud Deployment Models:
- Public, Private, and Hybrid Clouds.
- Command to create a private cloud VM (OpenStack):
openstack server create --flavor m1.small --image cirros --nic net-id=private-net myVM
2. Benefits of Cloud Computing
- Scalability and Elasticity:
- Auto-scaling in AWS:
aws autoscaling create-auto-scaling-group --auto-scaling-group-name my-asg --launch-configuration-name my-lc --min-size 1 --max-size 5 --desired-capacity 2
- Cost Reduction:
Use cost management tools like AWS Cost Explorer or Google Cloud Billing.
3. Common Cloud Services
- Storage:
- AWS S3 bucket creation:
aws s3 mb s3://my-bucket
- Google Cloud Storage bucket creation:
gsutil mb gs://my-bucket
- Compute:
- Launch a VM in Google Cloud:
gcloud compute instances create my-vm --zone=us-central1-a
- Networking:
- Create a VPC in AWS:
aws ec2 create-vpc --cidr-block 10.0.0.0/16
4. Cloud Governance and Security
- Cost Management:
- AWS Budgets setup:
aws budgets create-budget --account-id 123456789012 --budget file://budget.json
- Security Best Practices:
- Enable MFA for AWS IAM users:
aws iam enable-mfa-device --user-name my-user --serial-number arn:aws:iam::123456789012:mfa/my-user --authentication-code1 123456 --authentication-code2 654321
5. Future Trends in Cloud Computing
- AI, Machine Learning, and Automation.
- Hybrid and Multi-cloud solutions.
- Containers and Microservices.
- Deploy a Kubernetes cluster:
kubectl create deployment my-app --image=my-app-image
