Server virtualization is a process by which server software is separated from the physical server hardware, allowing multiple VM virtual servers to run on a single physical server.
This process creates an environment in which each server virtual runs its own operating system and set of applications independently of all others. Server virtualization is central to cloud computing and supports various hybrid cloud models.
Organizations can set up or have web hosting services delivered relatively cheaply, making the most of the company's computing, storage and networking resources. infrastructure as a whole.
To implement server virtualization within an organization, it is important to follow some key steps:

Create a plan: Ensure all stakeholders understand why your organization needs a virtualization platform and consider costs and potential complexities.
Analyze the market and competition: Evaluate the hardware and potential solutions to get an idea of ​​the scope of the project.
Test and experiment: Test all potential solutions to see how they work in reality and how they impact daily operations.
Evaluate the requirements business: Make sure the proposed solution meets your organization's specific virtualization needs.
Start small and scale progressively: Experiment with a small deployment on non-critical systems to learn what is needed for day-to-day running and management.
Develop guidelines: Analyze and plan VM provisioning, their lifecycle and how they will be monitored.

Choose the right tools: Consider purchasing additional tools that help you take advantage of the solution's more advanced features and better manage the system.
Don't neglect automation: Make sure your IT staff knows and understands the practices and tools for automation.

There are several types of server virtualization, including operating system-level virtualization, which eliminates the need for a hypervisor and allows you to support thousands of VMs on a single server. However, this typology has a disadvantage, namely a single point of failure, since if the host operating system is attacked or fails, all the VMs contained in it are affected.
