Why it matters: At scale, design choices directly impact reliability, latency, and cost. Wrong decisions compound across jobs and teams.

EDA in business context: (1) Load data, check shape, dtypes. (2) Describe stats, nulls, duplicates. (3) Visualize distributions, correlations. (4) Identify: outliers, missing patterns, key segments. (5) Summarize: 'X% of revenue from segment Y; nulls in Z suggest data issue.' Best practice: Document assumptions; tie to business questions; recommend next steps.

Scalability trade-offs: Partition/parallelism limits; single points of failure; horizontal vs vertical scaling. Cost implications: Sizing, spot vs reserved, optimization ROI.

Pro Tip

Red Flag: EDA without business tie. Pro-Move: 'Document; business impact; next steps.'
