AWS Core Services Explained: EC2, S3, IAM, and Serverless

The tech industry is in a "split reality." While headlines scream about layoffs, the demand for Cloud Infrastructure talent is at an all-time high. This video breaks down the massive cloud skills gap and provides a technical deep dive into the AWS ecosystem. We cover everything from the historical shift from physical servers to the "utility model," as well as the core pillars of AWS architecture, including security (IAM), compute (EC2), storage (S3), and the power of Infrastructure as Code. Whether you're a beginner or looking to advance your career, this session explains the "physics of failure" and the blueprints of the modern cloud.
