What is Microsoft Windows Server ?


Beside choosing the right physical server, the choice of operating system is undoubtfully important too.

Microsoft Windows Server is the platform for building an infrastructure of connected applications, networks, and web services, from the workgroup to the data center. It bridges on-premises environments with Microsoft Azure, adding additional layers of security while helping you modernize your applications and infrastructure.

Microsoft Windows Server Standard Edition

Standard Edition includes up to two (2) virtual instances of the operating system environment (VMs / OSEs) or up to two (2) Hyper-V Containers when all physical cores in the Server are licensed. For every two (2) additional OSEs or Hyper-V Containers, all the cores in the Server must be licensed again.

 

Microsoft Windows Server Datacenter Edition

Datacenter Edition includes unlimited virtual instances of the operating system environment (VMs / OSEs) and Hyper-V Containers on the licensed physical server.

 

Licensing Requirements:

  • All physical cores in the Server must be licensed (Hyperthreading (SMT) does not count as actual physical cores)
  • A minimum of 8 cores must be licensed for each processor
  • A minimum of 16 cores must be licensed for each Server
