Server Description
A memory-intensive virtual server featuring a high RAM-to-core ratio and local SSD storage for demanding database and caching workloads.
Microsoft Azure FX4mds is an x86_64 architecture server within the FXMDVS family, virtualized using Microsoft Hyper-V. It features 4 dedicated vCPUs powered by Intel processors and is equipped with 84.0 GB of system memory, providing a high ratio of 21.0 GB of RAM per core. The instance includes 172 GB of local SSD storage and supports premium storage configurations, though it lacks integrated GPU hardware and complimentary public IPv4 addresses. Designed for memory-intensive operations, the FX4mds offers qualitative cost efficiency by allowing organizations to run RAM-heavy workloads without paying for unnecessary compute cores. This hardware profile is well-suited for database caching, in-memory data processing, and relational database management systems that require a dense memory footprint relative to virtual CPU capacity.
