The resources of most servers are used less than 15%, which leads to an increase in the number of servers, and the infrastructure itself becomes more complex. Server virtualization can solve these problems by allowing several operating systems to run on a single physical server in the form of virtual machines, each of which has access to the server's computing resources. In addition, server virtualization enables faster deployment of workloads, as well as improved application performance and availability.
Providing desktops as a managed service increases the responsiveness to changing business needs and new opportunities. This model helps companies to reduce costs and improve service levels, because virtualized desktops and applications are equally accessible to employees of the main office and branches, as well as remote, freelance and mobile employees who use the iPad and Android tablets.
Huge amounts of data and applications that process them in real time significantly increase the requirements for storages. Storage virtualization abstracts disks and flash drives on servers and merges them into high-performance storage pools with provision of resources in the form of software. Software storage is a new approach to data storage, which provides a much more efficient model of operation.
Network virtualization is the complete reproduction of a physical network by a software method. Applications in virtual networks work in the same way as in physical networks. Virtualized networks connect workloads to logical network devices and services, such as logical ports, switches, routers, firewalls, load balancers, VPNs, and so on. Virtual networks are similar to physical ones in terms of reliability and capabilities, but they also have a lot Additional operational benefits, such as independence from equipment.
Virtualization can improve the adaptability, flexibility and scalability of the IT environment and significantly reduce costs. In addition, virtualization accelerates the deployment of workloads, improves their performance and availability, and also automates many processes, resulting in the company's IT infrastructure becoming more manageable and economical.
