Day 37: Managing EC2 Access with S3 Role-based Permissions

☁️ Day 37: Managing EC2 Access with S3 Role-based Permissions | 100 Days of Cloud (AWS) Welcome to Day 37 of the 100 Days of Cloud (AWS) series! In this lab, you’ll learn how to securely connect an EC2 instance to an Amazon S3 bucket using IAM Roles and Policies instead of hardcoded credentials. 📌 Lab Objective: Create a private S3 bucket, configure IAM role-based permissions, attach the role to an EC2 instance, and verify secure access to S3. 🛠️ Task Requirements: EC2 Instance: xfusion-ec2 S3 Bucket: xfusion-s3-458538643604 IAM Role: xfusion-role Region: us-east-1 Required Permissions: s3:PutObject s3:GetObject s3:ListBucket 💻 What You’ll Configure & Verify: 🔹 Generate SSH key pair on AWS client host 🔹 Configure password-less SSH access to EC2 🔹 Create private Amazon S3 bucket 🔹 Create IAM policy for S3 access 🔹 Create IAM role and attach policy 🔹 Associate IAM role with EC2 instance 🔹 Upload files to S3 from EC2 using AWS CLI 🔹 Verify uploaded files using S3 list commands 🔹 Test secure role-based authentication 📚 What You’ll Learn: AWS IAM Roles and Policies Secure EC2 to S3 integration Amazon S3 bucket management Role-based authentication in AWS AWS CLI file upload operations EC2 instance profile configuration SSH key management Cloud security best practices 🌟 Why This Lab Matters: Using IAM Roles instead of access keys is a fundamental AWS security best practice. This lab demonstrates how cloud applications securely access AWS services without storing sensitive credentials inside servers. 🎯 Series: 100 Days of Cloud (AWS) Build strong AWS cloud and security skills step by step through hands-on practical labs. 🔔 Follow OtterTech for more AWS, Azure, Kubernetes, Docker, Linux, Networking, Security, and DevOps tutorials! #AWS #EC2 #S3 #IAM #CloudSecurity #AWSCLI #AmazonS3 #CloudComputing #Linux #Automation #IAMRole #DevOps #AWSSecurity #100DaysOfCloud #OtterTech #Day37
