Microsoft has announced a monster single-instance Azure VM that supports up to 12 Terabytes of memory being made available in the near future. This is the largest memory configuration for a single VM in the public cloud and is part of their M-Series of virtual machines. The new VM sizes will be based on Intel Xeon Scalable (Skylake) processors, which are optimized to be used in cloud infrastructures. These new large memory configurations are a continuing investment by Microsoft to offer memory intensive SAP HANA customers more options in order to increase performance.
