Implementing PostgreSQL databases on Azure VM instances with Dell APEX Block Storage for Azure provides customers with the option of using a public cloud platform while maintaining high-performance and scale for mission-critical applications. Customers can efficiently use the compute and storage resources independently to scale their setup on the Azure cloud platform.
The PostgreSQL database on Dell APEX Block Storage for Azure with locally attached NVMe SSD drives delivers a high random I/O performance with low latency. However, locally attached NVMe SSD drives are ephemeral, and data is lost when the instance stops. Whereas a PostgreSQL database on Dell APEX Block Storage for Azure with premium SSD drives provides persistent storage, high availability, and durability.
This solution provides consistent performance for PostgreSQL database workloads while maintaining the protection and resiliency of the data and delivers the highest performance for a read only and TPCB-like workload environment when Dell APEX Block Storage for Azure is distributed across different AZs in the cloud platform.
