Cloud Databases: Pros and Cons
summary
Describes migrating a MySQL cluster to Amazon Aurora (RDS) with a zero‑downtime process using S3 snapshots, RDS replicas across availability zones (and optional cross‑region), and changes to a PHP (Cake) app. Automation via Jenkins and shell scripts handled switching and autoscaling (with accepted ~10 minute scale‑up delay and occasional transient failed requests during instance removal); reserved instances and optimizations cut costs ~4×, and backup and disaster‑recovery workflows were validated.
