Cloud Computing
Domain: Computer Systems
🎯 Motivation
Using remote servers over the internet instead of local machines. AWS, Google Cloud, Azure are cloud providers.
📋 Concrete Example
Cloud: you need 100 GPUs for AI training. Buy: 10/hour x 100 = 10,000. Much cheaper for temporary needs.
🔗 Analogy
Cloud computing is like renting a hotel room instead of buying a house - you pay for what you use, when you use it. No maintenance, no upfront cost. But long-term, buying might be cheaper.
