Day 7 of My Cloud Journey: Getting Started with Docker & Containerization

Over the past few days of my cloud learning journey, I explored different parts of AWS infrastructure. From deploying applications to designing secure cloud networks, each day has helped me understand how modern cloud systems are built. Quick recap of the previous learning days: Day 3 – Deployed a web application on a Linux server using Amazon EC2 and Nginx Day 4 – Hosted a static website using Amazon S3 Day 5 – Explored backend services with Amazon RDS, DynamoDB, and AWS Lambda Day 6 – Built secure cloud networks using AWS VPC, VPC Peering, and Billing Alerts After learning about infrastructure and networking, the next logical step in my journey was: Containerization with Docker. Docker is one of the most important tools used in modern DevOps and Cloud Engineering workflows. 🚀 Objective of Day 7 The goal today was to understand: • What Docker is • Why containers are used in modern application development • How to run containers using Docker • Basic Docker commands and container lifecy
