Devops for Growth

Unikernels are a burgeoning technology, ripe for deployment in a range of situations, from cloud-hosted microservices to Internet-of-Things platforms. By compiling and linking only the required code, they offer a range of benefits over traditional OS-hosted deployments, notably efficiency and, through smaller attack surfaces, security. While increasing in maturity, to date they have remained something of a technologists' choice: technically compelling but requiring considerable effort to build, deploy and use.
To address this, some in the community have spent time trying to integrate unikernel management with the popular Docker container management stack. By enabling unikernels to be managed using the standard Docker command line tools, we bring all the ease-of-use and common understandings of that toolchain to bear on this exciting technology.
After giving some context to the challenges faced, we will demonstrate building and running a simple LAMP-like stack using Docker to build and manage Rumprun and MirageOS Unikernels.

Unikernels are constructed by combining application code with only the operating system components necessary for that code to run. The result is a highly specialized, single-purpose application which can be deployed directly to the cloud or onto IoT-like devices. Unikernels reduce software complexity by only including code that is required, resulting in portable applications with much smaller footprints and fast boot times.

UPDATED OCTOBER 2015: Unikernels are small, fast, easily deployable, and very secure application stacks. Lacking a traditional operating system layer, they pr…

The unikernel approach should not be limited to cloud workloads. The cloud infrastructure itself must be built around the same principles. Our goal is to be ab…

This talk will give an overview of Unikernel technology: what they are, why they are important, and what challenges and innovations are likely to appear in the…

In most current microservice-based architectures, the machine images powering the microservice are quite traditional: a full software stack from operating syst…

Over the last several years, I and others have talked about the promise of unikernels — single-purpose, lightweight virtual machines — in the cloud. Howeve…

Après la virtualisation avec les VM, les containers genre Docker, voici les unikernels.
Mais qu’est-ce que c’est?
En quelques mots parce que la sélection de liens qui suit l’explique très bien :

L’approche unikernel consiste a compiler l’applicatif, par exemple une JVM java 8 et tout ce qui va bien avec (notre code applicatif, etc…), avec une librairie Operating System minimal. Cela produit une image d’OS bootable dans une VM
