Server Core is a minimalistic Microsoft Windows server installation option.
You can install SQL Server on a Server Core installation of Windows Server 2008 R2 SP1 or Windows Server 2012. This option of windows server 2012 provides a minimal environment for running specific server roles. This helps to reduce maintenance and management requirements and the attack surface for those server roles. Starting with Windows Server 2012, it is possible to transition between Full Server and Server Core without reinstalling the operating system.
Server Core is designed to provide an environment that reduces:
- Servicing requirements
- Management requirements
- Attack surface
- Disk space usage
- Memory (RAM) usage
Server Core supports the following server roles on Windows Server 2012 and Windows Server 2012 R2:
- Active Directory Domain Services (AD DS)
- Active Directory Lightweight Directory Services (AD LDS)
- DHCP Server
- DNS Server
- File Services
- Print Services
- Streaming Media Services
- Web Server (IIS)
- Active Directory Certificate Services
