Start with:
- Cloud Fundamentals (EC2, VPC)
- Networking (Route 53, ALB/NLB, CloudFront)
- IaC (Terraform, CloudFormation, CDK)
- Containers & Orchestration (ECS, EKS, Fargate)
- Security & IAM (IAM Policies, KMS, Secrets Manager, SCPs)
- Serverless (Lambda, API Gateway, EventBridge, Step Functions)
- CI/CD & Automation (CodePipeline, CodeBuild, GitHub Actions)
- Monitoring & Logging (CloudWatch, X-Ray, AWS Config, CloudTrail)
- Storage & Databases (EFS, RDS, DynamoDB, ElastiCache)
- Cost Management (Budgets, Cost Explorer)
Pick one cloud provider first. This is for AWS, but you can choose any to start with. Stop jumping from one to the other before gaining strong hands-on experience.

Terraform Commands for IaC
1. Initialize Terraform
terraform init
2. Apply Terraform Configuration
terraform apply
3. Destroy Resources
terraform destroy
Kubernetes Commands for Container Orchestration
1. Deploy a Pod
kubectl apply -f pod.yaml
2. Check Pod Status
kubectl get pods
3. Expose a Service
kubectl expose deployment my-deployment --type=LoadBalancer --port=80 --target-port=8080
What Undercode Say
Mastering cloud engineering requires a strong foundation in core AWS services, Infrastructure as Code (IaC), and container orchestration. Start with AWS CLI commands to manage EC2, S3, Lambda, and RDS. Use Terraform for IaC to automate infrastructure deployment. For containerized applications, Kubernetes is essential for orchestration. Always monitor your resources using CloudWatch and optimize costs with AWS Budgets.
