What is a virtual machine?
A virtual machine is a software environment that faithfully reproduces the operation of a physical computer. It is hosted on a server and shares resources (CPU, RAM, storage) with other virtual machines via a hypervisor. Thus, you can create, deploy and isolate multiple "Posts" or "servers" on the same infrastructure, without the usual physical constraints.
Key points :
- Complete isolation : Each VM works independently of the others.
- Easy deployment : A simple image file or a few clicks are enough to create a new environment.
- Scalability : Resize RAM or CPU power as your needs grow.
Why choose a virtual machine?
Flexibility and mobility
- Remote access: Your teams can work on their virtual environment from any device (PC, tablet, smartphone).
- Multi-environment : Quickly develop or test various systems (Windows, Linux or specific application versions) without blocking your core infrastructure.
Enhanced security
- Centralized data : Sensitive information remains in a secure datacenter, rather than scattered on physical workstations.
- Advanced access control : Manage updates, user rights and backups centrally, limiting potential breaches.
Cost optimization
- Reduced maintenance : Less equipment to acquire, store and maintain.
- Pay-as-you-go : Pay only for the resources you actually use, giving you more control over your IT expenses.
Concrete use cases
- Development and testing : DevOps teams can clone an environment to test applications or updates without impacting production.
- Telework and mobility : Give your employees a virtual office accessible from anywhere, promoting flexibility and productivity.
- Training : Create pre-configured VMs to introduce your teams to new tools or business scenarios, without requiring specific equipment.
How to deploy a virtual machine optimally?
- Properly size
Accurately assess the RAM, CPU power and storage capacity required for your applications. - Monitor performance
Implement monitoring tools to avoid saturation (CPU, RAM, bandwidth). - Securing the environment
Use a firewall, strong authentication, and outsource your backups for greater resilience.
