Which compute shape possesses the highest total memory per node?

The choice of BM.Standard.E2.128 as the option with the highest total memory per node is grounded in the understanding of the nomenclature used to describe the different compute shapes. In this context, "BM" indicates a bare metal instance, which generally offers more direct access to the physical hardware, providing increased performance and efficiency for memory-intensive applications compared to virtual machines, denoted by "VM".

Among the options listed, the distinction between these compute shapes primarily revolves around their allocated memory resources. The figures associated with each shape (e.g., 64, 128, and 192) suggest the memory in gigabytes that each configuration supports. The BM.Standard.E2.128 specifically offers 128 GB of memory per node, which is substantial.

Given that the BM.Standard.E2.192 is also a bare metal instance but might initially seem to have the highest memory based on the number, 192 does not actually correlate to the most favorable allocation according to the naming convention typically used for these configurations. The naming structures imply certain boundaries and optimizations related to resources allocated per node, often differing between bare metal and virtual instances.

Therefore, the choice of BM.Standard.E2.128 correctly identifies a robust balance and significant memory provision
