Web Service Appliance Based on Unikernel

Mini-OS is a tiny OS (operating system) kernel distributed with Xen Project Hypervisor. It is mainly used as an OS for stub domain aimed at Dom0 disaggregation and also a stepping stone for Unikernel development. We implemented a simple http server on Mini-OS, and built Mini-OS into a web service appliance. We evaluated its performance compared with the same implemented server on Ubuntu PV (para-virtualization) DomU, and achieved about 39% performance improvement. The results show that Mini-OS can be a web service appliance and has a good performance.
