While basically built for Linux, Ceph has been also partially ported to Windows platform. It is production-ready for Windows Server 2016 (some commands might be unavailable due to lack of UNIX socket implementation), Windows Server 2019 and Windows Server 2022 , but testing/development can be done also on Windows 10 and Windows 11 .
For example, to develop a web application, the architect defines the stack as the target operating system, web server, database, and programming language. Another version of a software stack is operating system, middleware , database, and applications. [ 2 ]
