CBL-Mariner continues to serve a variety of purposes at Microsoft from running within Azure infrastructure to also finding use within Windows Subsystem for Linux and other Microsoft applications. While it began as a server/infrastructure-focused Linux initiative, with time it's grown in scope and now includes more HPC support and adding more packages to round out the experience including for desktop use-cases.
