Phase 2: Core AWS Services & Global Infrastructure

This phase introduces you to the core building blocks of the AWS Cloud – its global infrastructure and the fundamental AWS services across key categories like compute, storage, networking, and databases. Understanding these foundational elements is crucial for anyone using AWS.

💡 First Principle: The First Principle is that AWS provides a highly scalable, reliable, and globally distributed infrastructure, offering a vast array of specialized services that can be combined to build virtually any cloud-based application or system. This enables users to innovate rapidly and manage their IT resources more efficiently.

You will learn about AWS Regions, Availability Zones, and Edge Locations, as well as the basic purpose and common use cases for essential AWS services that all cloud practitioners should know.

The focus is on remembering and understanding the basic functionality and relevance of these core services, which is crucial for the CLF-C02 exam.

Scenario: You're starting to explore AWS and need to understand where your applications will run, how data is stored, and how various AWS components interact.

Reflection Question: How does AWS's globally distributed infrastructure and its vast array of specialized services fundamentally enable businesses to build scalable, reliable, and innovative cloud-based applications efficiently?

💡 Tip: Focus on the primary purpose and benefit of each service, and how it broadly fits into an IT solution. Don't get bogged down in deep technical details.
