How Software Development Has Changed Over Time

Summary

Development shifted from multi-year waterfall cycles with manual disk deployments to iterative agile sprints, continuous deployment pipelines, automated tests, and declarative cloud infrastructure.

Core Principles

From punch cards and waterfall models to continuous integration, micro-deployments, and declarative infrastructure.

Understanding this topic provides critical context for software design, runtime execution, and computational trade-offs.

Why It Matters in Computing

In modern software systems, abstractions exist to shield developers from lower-level mechanics. However, when systems scale, encounter latency spikes, or experience production failures, understanding these fundamentals allows engineers to diagnose root causes and make optimal architectural choices.
