Azure runs some of the largest in-memory workloads in the world and we continue to invest in meeting the evolving needs of our customers. In October 2019 we launched 6TB and 12TB VMs for workloads with high memory and high-performance CPU needs. In response to customer demand for similar high-performance CPU needs in medium memory sizes(<4TiB), today we are announcing the public preview of Msv2 medium memory VM sizes providing a 20% increase in CPU performance, increased flexibility with local disks, and a new intermediate scale up-option.
Key features on the new M-series VMs for memory-optimized workloads
We created this new set of VMs based on direct feedback from customers that run massive, mission-critical workloads on Azure and demand the best combination of price and performance. During our private preview, several customers such as EPIC Healthcare unlocked gains from the new VM sizes. In their own words:
“Moving from the M128s_v1 running Cache to the M128s_v2 running IRIS, we saw the scalability of a single operational database server increase by 80%[1]. With these gains, we expect our customers to scale further in Azure.”
