AWS S3 & Lambda..

☁️ What is AWS S3?

🪣 S3 (Simple Storage Service) is like a giant digital warehouse where you can store all types of files — images, videos, PDFs, logs, backups, and more.

📁 In S3, you create a bucket, which works like a folder. You can upload files into it, and each file becomes an object with its own unique URL.

🔐 You can control who can access which file — some can be public (like for a website), and others private (for secure storage).

🛠️ Unlike Google Drive (which is used manually), S3 is designed for developers and apps. You interact with it using the AWS Console, CLI, or code.

🌐 For example, you can host a static website using S3 by just uploading your HTML and image files.

⚡ What is AWS Lambda?

🧠 Lambda is like a smart worker that sleeps quietly and only wakes up when there's a job to do.

🛎️ You don't need to run or manage any server. You just write your code (in Python, Node.js, etc.) and tell AWS:
"When this happens, run this code."

📷 For example, when an image is uploaded to S3, Lambda can automatically resize it, watermark it, or process it in some way — without you doing anything manually.

🕒 It can also run on a schedule, like sending reports every night at 2 a.m., or automatically responding when a form is submitted or a payment is received.

💸 You only pay when Lambda runs. No server bills. No always-on machines. It's truly serverless.

🎯 As you rightly said:
"In Lambda, we assign a task — and it just does the job

🪣AWS S3 is a cloud storage service that allows developers to store and access files securely. 🧠AWS Lambda is a server-less computing service that automatically runs code in response to events, such as file uploads to S3, without the need for server management.
