Applies to: ✔️ Linux VMs ✔️ Windows VMs ✔️ Flexible scale sets ✔️ Uniform scale sets

The 'M' family of VM size series are one of Azure's ultra memory-optimized VM instances. They're designed for extremely memory-intensive workloads, such as large in-memory databases, data warehousing, and high-performance computing (HPC). Equipped with substantial RAM capacities and high vCPU capabilities, M-family VMs support applications and services that require massive amounts of memory and significant computational power. This makes them particularly well-suited for handling tasks like real-time data processing with SAP HANA, complex scientific simulations, and large-scale enterprise resource planning (ERP) systems, ensuring peak performance for the most demanding data-centric applications.

Workloads and use cases

In-Memory Databases: The M-family is particularly effective for running in-memory databases like SAP HANA that require large amounts of RAM for real-time data processing and analytics.

Big Data Applications: The M-family is ideal for handling big data applications that need to process and analyze huge datasets in memory, improving performance and reducing the time to insights.

Data Warehousing: M-family VMs provide the performance and memory needed for data warehousing applications, facilitating faster queries and better handling of large volumes of data.

Enterprise Applications: The M-family supports large-scale enterprise applications, including ERP and CRM systems, which benefit from having more memory to manage larger datasets and more complex transactions efficiently.

Heavy Workloads in Virtualized Environments: The M-family is well-equipped to handle heavy virtualized environments, offering substantial memory for hosting multiple virtual machines and applications on a single physical server.

M-series

The M-series offers a high vCPU count (up to 128 vCPUs) and a large amount of memory (up to 3.8 TiB). It's also ideal for extremely large databases or other applications that benefit from high vCPU counts and large amounts of memory. M-series sizes are supported both on the Intel® Xeon® CPU E7-8890 v3 @ 2.50GHz and on the Intel® Xeon® Platinum 8280M (Cascade Lake).
