Virtual Machine vs Containers

When you use a Virtual Machine (VM), you are doing what is called heavy virtualization. Indeed, you recreate a complete system in the host system, so that it has its own resources.

The isolation with the host system is therefore complete; however, this brings several constraints:

• A virtual machine takes time to start ;
• A virtual machine reserves resources (CPU/RAM) on the host system.

But this solution also has many advantages:

• A virtual machine is completely isolated from the host system;
• The resources allocated to a virtual machine are totally reserved for it;
• You can install different OS (Linux, Windows, BSD, etc.).

But it happens very often that the application it runs does not consume all the resources available on…
