📅 Day 11 🚀 Amazon S3 | Simple & Secure Cloud Storage
In AWS DevOps projects, storing data safely and accessing it anytime is very important.
AWS provides Amazon S3 — a highly scalable object storage service used worldwide.
S3 helps us:
✔ Store any type of data (images, logs, code, backups, videos)
✔ Access data anytime from anywhere
✔ Host static websites like portfolios & landing pages
✔ Store CI/CD build artifacts
✔ Maintain backups & version control
✔ Reduce cost using storage classes & lifecycle rules
📌 S3 = Storage + Security + Scalability + Cost Optimization
It protects data with encryption, IAM policies & multi-AZ durability (11 9’s 🤯),
making it a must-know service for DevOps engineers! 🔥
🚀 How to Create an S3 Bucket
1️⃣ Login to AWS Console
2️⃣ Go to S3 service
3️⃣ Click Create bucket
4️⃣ Enter a unique bucket name (globally unique)
5️⃣ Choose Region (ex: ap-south-1)

1️⃣ Upload index.html
2️⃣ Go to Properties → Static website hosting → Enable
3️⃣ Select index.html as the default file
4️⃣ Make index.html public
5️⃣ Copy Website Endpoint URL
6️⃣ Open in browser → 🎉 Website is Live
(Optional) Use CloudFront for HTTPS + global performance
