Tech Fundamentals 2026 Edition
Just enough tech to make cloud, DevOps, security, and systems engineering 10× easier. This comprehensive survey builds foundational knowledge across computing, networking, the web, security, cloud, storage, and delivery, explained clearly with analogies, real-world examples, and hands-on labs. Start from zero and build intuition fast, with a focus on practical understanding over rote memorization. Updated for 2026 trends like zero-trust, cloud-native, APIs, and observability.
