Virtualization Manage IT infrastructure resources in an effective way
Virtualization / Virtual Machine
Virtualization is a process of creating virtual representation of IT resources. For example IT infrastructure more efficiently. Virtualization is the most effective way to reduce IT spending while increasing productivity and efficiency.
Virtual Machine – VM – A virtual machine is an additional operating environment created within another computer. It provides the end-user with access to the same resources on the virtual machine as it would have on the main operating system.
In the case of servers on which VMs are installed, many operating systems can operate simultaneously without affecting each other. Each self-contained virtual machine is completely independent. They are managed by software called a hypervisor.
Why do companies use virtual machines?
Because each virtual machine is a separate environment, it is possible to allocates computing resources between them: CPUs, memory, hard drives, network interfaces and other devices.
Because virtual machines are separate environments, their mutual work does not affect each other. In addition, it is also possible to move and copy virtual machines.
How to protect your VM?
Backup of virtual servers
Virtual server backups can be performed by conventional backup software. Although this is the most straightforward approach, it often leads to resource contention. The additional resources needed to execute a backup may compromise the performance of the virtual machines on the physical server being backed up.
Due to the features of most modern backup software – which include snapshot management, data recovery elements, cloud support, VM protection – backups can do so much more than simply restoring data in the event of a storage or server failure.
Such an up-to-date enterprise backup solution for virtual environments is Storware vProtect. It is designed to back up the virtual machines that are running on Open Source platforms.
