In this blog, we’ll go one level deeper and: 🔥 Create an EC2 instance using raw HTTP requests with AWS Signature Version 4 (SigV4) 🧠 boto3 is Just a Wrapper When you run something like: ec2 . run_instances (...) Behind the scenes, boto3: Builds an HTTP request Signs it using AWS Signature Version 4 Sends it to AWS APIs In this blog, we’ll do all of that manually . ⚙️ What We’re Building We’ll create a Python script that: Uses requests Implements AWS SigV4 authentication Launches a real EC2 instance No SDK. No shortcuts. 🔄 High-Level Flow Client → Canonical Request → String to Sign → Signature → AWS API → Response 🔐 Understanding AWS Signature Version 4 (SigV4) AWS secures every API request using SigV4. It ensures: Authentication (who you are) Integrity (request not tampered) Let’s break it down. 🔹 Step 1: Create Canonical
