Pro Can run on bare hardware as well as hypervisors
Rumprun is multiplatform and can run on different types of platforms, including hypervisors (such as Xen and KVM) as well as running on bare hardware.
Pro Can be integrated to existing systems
Rump provides kernel-quality drivers for a variety of use-cases from filesystem to PCI device drivers. Because of this, they can be integrated into existing systems or can be run as standalone unikernels on hypervisors.
Con Has some complexity added because it's not based on a language with process isolation
Since C and C++ (with which Rumprun is built) have no language level isolation, Rumprun doesn't have process isolation either. Because of this, sensitive components have to be split into different nodes, isolated by either different virtual machines or different computers.
