Is the comparative study for the service between VM and container available and does it consider the Sustainable IT impacts of each solution?
Precisions
Virtual machines and containers are 2 virtualization techniques. Virtual machine technology uses a lot of duplications (operating system for example) and creates virtual components associated with physical components. The container mode is based on the physical components of the hardware and uses them more natively by limiting the duplications of software components. From a Sustainable IT point of view, containers are often more efficient but the technology is less widely deployed.
