The status quo is that most microservices are built on top of a complete Linux kernel and distribution. It is as if you wanted to enable individual air travel with only one passenger seat per aircraft but kept the powerful engines of a jumbo jet.
Unikraft is on a mission to change that! We have developed a truly modular unikernel common code base from which building tailored made (uni)kernels is orders of magnitude faster than in the past.
“With Unikraft, you don’t have to choose between unikernel projects that only work for a specific language or application, or projects that aim to support POSIX but do so while sacrificing performance and thus defeating the purpose of using unikernels in the first place” (Felipe Huici, Unikraft core contributor)
