What are virtual machines ?
Virtual machines are common today due to the increasing digitization of companies. They are often data center products.
It is able to run programs due to the allocation of host resources. These resources are simulated but identical to those of a real machine. To the user, it is a virtual PC, regardless of its memory and operating system (OS): it appears in front of him as a window.
Virtual machine is a simulation of a machine by software on a real machine : a virtual machine performs functions that differ from the real machine’s house. A virtual machine is actually a computer image that simulates a computer.
What are containers ?
Virtualization relies on software to simulate hardware functions and create virtual computer systems. This model allows IT departments to run multiple virtual systems on a single server.
Why use Docker containers? Docker is a containerization technology that makes it easy to manage dependencies at all levels development / deployment, within a project.
Available on Linux, Windows …, the Docker mechanism is centered around containers and their orchestration, which is why
How do technologies such as virtual machines and containers help improve operational efficiency?
Virtualization can improve data security by partitioning it, isolating services on different servers. Each virtual machine is isolated from other virtual machines, including the host system. This makes it possible to limit the risk of spreading in the event of a malware-type intrusion.
Containerization provides a way to virtualize resources with isolation guaranteed by the OS. Therefore, these resources are more easily transferred from one system to another.
Application development is also accelerated.
