☁️ AWS Sandbox — Learning Repository

A structured, day-by-day AWS learning journey covering core cloud services with hands-on notes, commands, and topic slides.

📌 About This Repository

This repository documents my personal hands-on practice with AWS. It is organized into two main sections — topic slide references and daily learning notes — covering everything from cloud fundamentals to advanced services like CloudFormation, Lambda, and VPC.

🛠️ AWS Services Covered

🔐 IAM — Identity and Access Management

• Creating users, groups, and roles
• Attaching managed and inline policies
• MFA setup and best practices
• Principle of least privilege

🖥️ EC2 — Elastic Compute Cloud

• Launching and connecting to instances via SSH
• Security groups and key pairs
• Instance types and pricing models
• Start, stop, and terminate via CLI

🖼️ AMI — Amazon Machine Images

• Creating custom AMIs from instances
• Launching instances from AMIs
• AMI sharing and copying across regions

⚖️ ELB & ASG — Load Balancer & Auto Scaling

• Application, Network, and Gateway Load Balancers
• Target groups and health checks
• Auto Scaling policies and launch configurations

🪣 S3 — Simple Storage Service

• Buckets, objects, prefixes
• Bucket policies, ACLs, versioning
• Static website hosting and lifecycle rules

🗄️ RDS — Relational Database Service

• Managed MySQL, PostgreSQL, and more
• Snapshots, backups, multi-AZ deployments
• Read replicas and scaling

📦 DynamoDB

• NoSQL tables, partition keys, sort keys
• On-demand vs provisioned capacity
• Global tables and streams

λ Lambda

• Serverless function creation and deployment
• Event-driven triggers (S3, API Gateway, etc.)
• Execution roles and environment variables

🏗️ CloudFormation

• Writing CloudFormation templates (YAML/JSON)
• Creating and managing stacks
• Parameters, outputs, and cross-stack references

🌐 Route 53

• Hosted zones and DNS records
• Routing policies (simple, weighted, latency, failover)
• Domain registration

🚀 CloudFront

• CDN distributions and origin setup
• HTTPS with ACM certificates

🔌 VPC — Virtual Private Cloud

• Subnets (public & private), route tables
• Internet Gateway, NAT Gateway
• Security groups vs NACLs
