1. Core AWS Services — Must Know

Category	AWS Service	What to Know
Compute	EC2	Launching servers, SSH, AMI, instance types
Storage	S3	Buckets, versioning, policies, lifecycle
Networking	VPC	Subnets, NAT, Security Groups, Route tables
IAM	IAM	Users, roles, policies, MFA
Databases	RDS	MySQL/PostgreSQL, backups, Multi-AZ
Serverless	Lambda	Triggers, Lambda execution role
Containers (Bonus)	ECS/EKS	Basics of Docker deployment
Load Balancing	ELB/ALB	Routing traffic, health checks
Monitoring	CloudWatch	Logs, alarms, metrics
Automation	CloudFormation/IaC	Deploying infra via code

2. Linux + Networking Fundamentals

Mandatory Basics:

• Linux commands (SSH, file management, permissions)
• Subnetting, IP, DNS, NAT, Load Balancer
• Firewall vs Security Groups

✅ You will run most AWS workloads on Linux.

• File & Directory Management- ls, cd, pwd, mkdir, rmdir, rm, cp, mv, touch, find
• File Viewing & Text Processing- cat, less, more, head, tail, tail -f, grep, cut, awk, sed
• Permissions & Ownership- chmod, chown, chgrp, umask
• Process Management- ps, top, htop, kill, killall, nice, renice
• Networking- ipconfig/ip a, ping, curl, wget, netstat, ss, scp, ssh, traceroute
• Disk & Storage-df -h, du -sh, lsblk, mount, fdisk
• System & Package Management- uname -a, uptime, free -m, systemctl, apt/yum/dnf
• Other Bonus (Very Important for DevOps)- journalctl, crontab, docker, kubectl, env

3. Hands-on Practical Skills-

• Host a website: S3 website hosting, EC2 Webserver (Apache), connect EC2 to RDS, Domain+SSL+ ACM
• Secure infrastructure: IAM roles vs policies
• Automation: Create VPC using Terraform, CI/CD Pipeline using Codepipeline+ GitHub

4. CI/CD + DevOps Basics (Highly Demanded)

• Git + GitHub + GitLab (Must)
• Docker Fundamentals
• AWS Pipeline/Jenkin

5. Programming / Scripting- 

1. Python for AWS
2. Bash for Automation
