2. What happens to read replica if Primary database is deleted? Scary, but anything can happen :-).
This video delves into critical considerations regarding the high availability of AWS Relational Database Service (RDS) instances in scenarios involving failover or unexpected issues impacting the primary database. The database topology discussed here incorporates a multi-Availability Zone (AZ) RDS database with a read replica situated in one of the availability zones. Grasping the significance of the read replica within your database topology is pivotal for constructing a resilient system.
In the realm of database architecture, the role of the read replica is key to ensuring continuity in the face of potential disruptions. It emphasizes that making informed architectural decisions involves a strategic trade-off between cost considerations and achieving optimal availability.
By comprehending the intricacies of leveraging read replicas within your database infrastructure, you gain the insight needed to strike a balance that aligns with your business objectives. This understanding empowers you to make strategic choices that not only meet your availability targets but also align with your cost-efficiency goals, ultimately contributing to the robustness and resilience of your overall system architecture.
