MirageOS is a new and rising trend when it comes to talking about cloud computing. More and more services are being relocated into modern cloud infrastructures, due to a lot of advantages like i.e. reduced costs, maximum flexibility and high performance. Todays services normally depend on big virtual machines (like i.e. Ubuntu Xenial with a size of ~1,5 GB) with a lot of software on it. The service which is running on these virtual machine only needs a very small subpart of the whole software and dependencies which are installed. Also the unneeded additional software running on the virtual machines offers a huge attack surface for hackers. Since data often is a highly valuable asset for a company and exposing it would lead to a huge profit collapse, security gains more and more importance. MirageOS is a minimalistic approach to kick out all unneeded layers and dependencies and deploy as less code as possible. This approach is highly efficient and fits in perfectly in modern microservice-architectures. If MirageOS will be accepted by users in the future, it could possibly replace modern approaches like i.e. Docker or classic virtual machines in the context of cloud-environments.
