An ERP application holds the full database in memory for fast access. Which Compute Engine resource configuration is most appropriate?

The M1 machine type (Memory-optimized) is designed for memory-intensive workloads, making it ideal for an ERP application that holds its entire database in memory. This type provides the highest memory-to-vCPU ratio, ensuring sufficient RAM for the application to operate efficiently. Preemptible instances are not suitable because they can be terminated at any time, which would disrupt the ERP application. GPUs are for accelerating specific computational tasks like machine learning, not for general-purpose memory-intensive applications. Local SSDs provide high I/O performance but are not the primary concern when the database is held entirely in RAM; the core requirement is abundant memory.
