The ZFS filesystem is an advanced technology that combines a traditional filesystem with a logical volume manager. It is designed with protection against data corruption as a primary goal, with other very useful features including copy-on-write (incremental) snapshots, continuous integrity checking and automatic repair, compression, etc.
FreeBSD is famous for its robust networking stack, sustaining heavy loads with great availability and performance. It runs the full variety of Internet services (DNS, web, mail, etc.) and has a proven track record of powering some of the busiest sites in the world. This makes FreeBSD one of the best platforms for edge routers and network servers.
FreeBSD has a full set of security features – it supports three bundled stateful/stateless firewall packages, a variety of Intrusion Detection Systems (IDSs) / Intrusion Prevention Systems (IPSs), several types of VPN services, monitoring tools, etc. It is widely used as a perimeter firewall on its own, as well as internally used in many commercial firewall products.
FreeBSD provides two levels of virtualization, suitable for different business needs. Jails is the native, operating system level virtualization, which allows running isolated instances of FreeBSD and keeping services contained with negligible performance overhead. FreeBSD also supports full virtualization through bhyve and VirtualBox, allowing it to host other operating systems as well. These capabilities make FreeBSD an ideal platform for hyper-converged systems and private cloud servers.
