AWS Cloud Tutorial

AWS Cloud Tutorial really means and — more importantly — what AWS itself is, because most people use the phrase “AWS Cloud Tutorial” when they want to learn Amazon Web Services from scratch.

Let’s go step-by-step like a real classroom session — no rush, lots of examples, analogies, and practical thinking.

1. First — What even is “Cloud Computing”? (Super basic foundation)

Think about your house in the old days:

• You bought a big inverter + batteries → for power backup
• You bought a huge water tank → for water storage
• You bought your own generator → just in case
• You bought AC, fridge, TV — everything yourself

Very expensive, you maintain everything, if anything breaks → you call technician, lots of headache.

Now modern apartments:

• Electricity comes from the grid (pay only for units you use)
• Water comes from society supply
• Internet from Jio/Airtel fiber
• You don’t own the power plant or water purification plant

You just pay for what you use and someone else maintains the big infrastructure.

Cloud computing = same idea but for IT/computers.

Instead of buying your own servers, buying licenses for software, hiring people to maintain cooling + UPS + security → you rent computing power, storage, databases from big companies like Amazon, Microsoft, Google.

You pay only for what you actually use (like electricity bill).

2. So what is AWS exactly?

AWS = Amazon Web Services

It is Amazon’s cloud computing platform. Launched in 2006. Today (2026) it is still the #1 cloud provider in the world (~31-33% market share).

AWS offers 200+ services — but you don’t need all of them.

Think of AWS like a huge supermarket of IT tools:

• Want a virtual computer? → take from shelf called EC2
• Want unlimited photo/video storage? → take S3
• Want a MySQL/PostgreSQL database without managing server? → take RDS
• Want to run code without managing any server? → take Lambda

You pay only for seconds / GB / requests you actually consume.

3. Real-life everyday examples of AWS (things you already use!)

So when you watch a movie on Netflix → video is coming from AWS S3 + CloudFront in most cases.

4. Core AWS Services — The “Big 6” every beginner must know (2026 edition)

Let’s rank them by how often they appear in real projects & tutorials:

1. EC2 – Elastic Compute Cloud → Virtual machines (like your laptop/desktop but in cloud) Example: You want to host a Java Spring Boot app or a Python Flask website → launch one EC2 instance (t3.micro is free-tier eligible)
2. S3 – Simple Storage Service → Unlimited, super durable file storage (photos, videos, backups, website files) Example: Company wants to store 5 TB of customer photos → upload to S3 bucket (costs ~₹1,600–2,000 per month only)
3. RDS – Relational Database Service → Managed MySQL, PostgreSQL, Oracle, SQL Server Example: Your e-commerce app needs user orders database → create RDS PostgreSQL (AWS takes backups, patching automatically)
4. Lambda – Serverless computing → Run code without managing servers (pay per execution) Example: Resize image automatically when someone uploads photo to S3 → write small Python function → Lambda runs it (costs almost nothing for low traffic)
5. VPC – Virtual Private Cloud → Your private network inside AWS (like creating your own subnet at home) Example: You don’t want public to directly access your database → put it in private subnet inside VPC
6. IAM – Identity & Access Management → Who can do what (very important for security) Example: Give your developer friend only S3 read access — not delete access — using IAM policy

5. How does a typical “AWS Cloud Tutorial” flow look like? (Most popular path in 2026)

Most good tutorials / YouTube full courses / Udemy / official AWS follow almost same sequence:

1. Create free AWS account (always use free tier carefully!)
2. Understand Billing & Free Tier (very important — don’t get surprised bill)
3. IAM basics (create user, never use root account)
4. Launch first EC2 instance → connect with SSH / RDP
5. Host static website on S3
6. Create RDS database → connect from your app
7. Deploy simple serverless API with Lambda + API Gateway
8. Learn VPC, subnets, security groups (network security)
9. Use CloudWatch for monitoring + alarms
10. Little bit of CI/CD with CodePipeline or GitHub Actions

After this → you can pick specialization:

• DevOps → ECS, EKS, Terraform
• Data → Glue, Redshift, Athena
• AI/ML → SageMaker, Bedrock
• Security → GuardDuty, Security Hub

6. Quick Hands-on Mini Example (do this in free tier)

Goal: Host your photo album online for free

1. Go to https://aws.amazon.com → Create account (use student/credit card — free tier 12 months)
2. Go to S3 service
3. Create bucket → name like my-hyderabad-photos-2026 (must be globally unique)
4. Upload 5–10 photos
5. Enable “Static website hosting”
6. Set index document = index.html (create simple HTML with <img src=”photo1.jpg”>)
7. Open the website endpoint → boom! Your photos are live on internet

Cost? Usually ₹0 in first year if under free tier.

Quick Summary Table – AWS vs Traditional

So when someone says “AWS Cloud Tutorial”, they usually mean:

“Teach me how to start using Amazon’s cloud platform from zero — with examples, console screenshots, and small projects.”
