Learn why RDS Read Replicas defeat Multi-AZ for read scaling, and how to size them correctly. A critical SAA-C03 scenario analyzing read traffic offloading strategies.
When scripted analytics workloads impact production database performance, should you scale horizontally with Read Replicas or vertically with Multi-AZ? This drill dissects the decision matrix for the AWS Solutions Architect Associate exam.
A simulated SAA-C03 scenario exploring how to architect high availability for a mission-critical web application using Aurora PostgreSQL and Auto Scaling groups, focusing on the balance between availability guarantees and operational simplicity.
This SAP-C02 scenario explores converting a brittle single-instance application stack into a resilient architecture using Multi-AZ RDS, ElastiCache replication, and Auto Scaling—analyzing the FinOps impact and decision logic behind each component choice.
When scaling a stateful web application across multiple Availability Zones, local EBS storage creates data silos. This drill explores the architectural decision between EBS replication, session affinity, and shared file systems like Amazon EFS.
