advantages of server virtualization
Today, multiple virtual machines can be implemented on a single physical server . This solution, which we know as Virtualization, has quickly opened its place in large and extensive services. In the following, we will discuss 5 important advantages when deciding to move towards server virtualization.
First advantage: less physical server
The first advantage of virtualization is quite obvious. Because many virtual machines can run on a single physical server, the need to purchase and maintain multiple servers will be eliminated and a significant portion of the cost will be saved. In a traditional IT infrastructure, many servers are too large to avoid the pressures associated with overload. Grouping several virtual machines in one place makes it possible to better exploit a virtual server.
Second advantage: better access
Today, virtualization solutions have increased the desire to use virtual machines. Awareness that it is possible to move a virtual machine from one physical server to another (even without having to stop it) will add to its fans. This feature is a key element to increase the level of access to your services. Using two physical servers doubles the virtualization infrastructure. In the event that a problem occurs with one of the two servers, the virtual machines are automatically transferred to the second server.
Third advantage: better performance
Another advantage of using virtual machines between physical servers is that the workload is distributed among the servers. When the working pressure of a virtual machine becomes too high, the rest of them can use a more secluded physical server. Critical tasks can also continue to work better by allocating more resources from the CPU, memory and disk space. Therefore, the size of virtual machines can be programmed according to the tasks they have to perform.
Fourth advantage: more security
In traditional IT infrastructure, file sharing, messaging, and even a web server all run on the same server. Therefore, if an email is infected by malware, all other services hosted on this machine will also be compromised. Virtualization can be used to separate different tasks from one physical server to several virtual machines. As a result, all these services are separated from each other and the vulnerability of one of them will not affect the rest.
Fifth advantage: The warranty is not obsolete
As part of a computer systems service, users often prefer to do their work on a dedicated server, as it can be configured in a specific and custom way. Ensuring the recovery and upgrade of this dedicated server, which is used only by one application, is often fruitless. The P2V (Physical to Virtual) tool makes it possible to convert most physical servers to virtual machines. After doing this, your virtualized ERP server will be able to move from one machine to a new server at the end of its life only through a virtual machine.
