📚 The Cloud: Quick Study Guide

• 💾 Cloud computing refers to the delivery of computing services—including servers, storage, databases, networking, software, analytics, and intelligence—over the Internet (“the cloud”) to offer faster innovation, flexible resources, and economies of scale.
• 📧 Common examples include: Email services (Gmail, Outlook), streaming services (Netflix, Spotify), social media (Facebook, Instagram), online storage (Google Drive, Dropbox), and online gaming.
• ☁️ Cloud services are typically categorized into three main types: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS).
• 🔒 Cloud services offer benefits like scalability, cost-effectiveness, accessibility, and automatic updates but also pose challenges related to security and data privacy.
• 🌍 The physical infrastructure supporting cloud computing is distributed across data centers located around the world.
