Scaling isn't about making things faster. It's about DISTRIBUTION.
In this AWS SAA-C03 exam question, we break down why Aurora Read Replicas are the answer for read-heavy e-commerce workloads, and why the other options fail.
? The Key Insight:
One overworked cashier collapses under load. Twenty cashiers in parallel handle everything. Same concept powers Netflix with 200M simultaneous viewers, Shopify on Black Friday, and banks during morning rush.
? What You'll Learn:
✓ Why Read Replicas distribute load across multiple servers
✓ Why Serverless doesn't solve read scaling
✓ Why a single instance is a single point of failure
✓ Why Multi-Master is built for writes, not reads
✓ How automatic failover keeps your system breathing
