Unikernels are an exciting new take on applications design and deployment. OCaml has been quietly forging ahead in the area with libraries like Mirage, whereby we can generate apps that operate at such a low level we don't even need operating systems on the backend anymore (removing 15 million lines of memory-unsafe code) - while at the same time, maintaining more reliable software with less effort through lightweight type-checked code sharing between server, browser clients, & native mobile apps.
