Mandatory Technical Skills for Freshers (Core Requirements)

1️⃣ Cloud Basics (AWS Fundamentals)

You should clearly understand:

• What is cloud computing? (IaaS, PaaS, SaaS)

• Why AWS? Benefits & Global Infrastructure

• Regions, Availability Zones, Edge Locations

• Shared Responsibility Model (AWS vs Customer responsibilities)

• Pricing & Cost optimization basics

2️⃣ Key AWS Services (Hands-on Skills → must do)

You should have practical experience deploying a basic project using:

Area	AWS Services to Learn	What to Practice
Compute	EC2	Launch Linux VM, Key pairs, Security Groups
Storage	S3	Host static website, object versioning & lifecycle rules
Networking	VPC, Subnets, Route Tables, NAT Gateway, Security Groups	Create a VPC with public & private subnets
IAM & Security	IAM Users, Roles, Policies, MFA	Secure access, least privilege
Databases	RDS (MySQL/PostgreSQL)	Create DB instance, connect from EC2
Monitoring	CloudWatch	Alarms for EC2/S3
Load Balancing	ELB + Auto Scaling	Deploy 2 instances behind Load Balancer

👉 If you can deploy a 2-tier architecture (EC2 + RDS + ALB + VPC + S3), you’re interview-ready.

3️⃣ Linux + Networking (Compulsory)

Because AWS heavily uses Linux…

✅ Linux Commands:
cd, ls, mkdir, cp, mv, chmod, chown, grep, top, ps, tail, vi

✅ Networking Fundamentals:

• DNS, DHCP, IP addressing, Subnetting

• HTTP/HTTPS protocols

• Firewall/Security Groups

---

4️⃣ DevOps Basics (Beginner Level Required)

Companies expect automation knowledge:

• CI/CD basics

• Git & GitHub workflow

• Shell scripting (basic level)

• Terraform (optional but gives advantage)

• AWS CLI + SDK basics

---

5️⃣ Database Skills

• Difference between SQL vs NoSQL

• Basic CRUD in MySQL

• DynamoDB basics (bonus)

✅ One Mini Project You MUST Build (Interview Portfolio)

📌 Deploy a web app with the below:

• Frontend static files on S3 + CloudFront

• Backend on EC2 inside a VPC

• Database on RDS

• IAM roles for secure access

• ALB + Auto Scaling

• Monitoring using CloudWatch

• Source on GitHub

➡ Interviewer will be impressed if you can explain architecture diagram + security setup.

✍ Sample Interview Questions You Must Prepare

✅ Cloud / AWS

• What is difference between EC2 and Lambda?

• Public vs Private subnet?

• How does Auto Scaling work?

• RTO and RPO?

✅ Networking

• CIDR notation?

• What are security groups vs NACL?

✅ Linux

• How to check running processes?

• File permissions meaning like drwxr-xr--?

✅ Practical Demo (very common)

• Launch EC2 + install a web server

• Upload objects to S3 & set access permissions
