    The importance of server virtualisation in modern IT infrastructure

    • Server virtualisation has emerged as a transformative technology that reshapes how organisations deploy, manage, and optimise their IT resources.
    • Server virtualisation is more than just a technological trend. It’s a fundamental shift in how IT resources are managed and utilised.

    Server virtualisation is a technology that allows multiple virtual servers to run on a single physical server. This approach has become a cornerstone of modern IT infrastructure, offering numerous benefits that can transform how organisations manage their resources. As businesses continue to navigate an increasingly complex and dynamic technological landscape, server virtualisation offers a strategic advantage. In this blog, you can understand what server virtualisation is and why it’s important for modern IT infrastructure.

    What is server virtualisation?

    Server virtualisation is a technology that allows multiple virtual servers to run on a single physical server by abstracting the underlying hardware. This approach enables a single physical server to act as if it were multiple separate servers, each running its operating system and applications independently. In computing, a single, physical server can be segmented into multiple isolated and individual virtual servers through some software. Each of these virtual servers is fully capable of independently running its operating system.

    why server virtualisation is important

    1. Resource optimisation: Traditional servers often operate at a fraction of their capacity. Virtualisation allows you to run multiple virtual machines (VMs) on a single physical server, making better use of the server’s hardware resources. By consolidating multiple server instances onto fewer physical machines, you minimise the overhead associated with running multiple physical servers, such as power consumption and cooling requirements.

    2. Cost savings: Fewer physical servers mean lower upfront costs for hardware. Virtualisation reduces the need for additional servers by consolidating workloads, which can significantly cut capital expenditure. Besides, savings extend to operational expenses as well. Virtualisation decreases the need for physical space, power, and cooling. Maintenance and management costs are also reduced since fewer physical machines need to be monitored and serviced.

    3. Improved flexibility and scalability: This flexibility allows organisations to respond rapidly to changing workloads or business requirements without the need for new physical hardware. Virtualisation facilitates scalability by allowing you to add more virtual servers or resources to a host server as demand grows, without having to invest in additional physical machines.

    4. Enhanced disaster recovery and business continuity: Virtualisation enables the creation of snapshots of virtual machines, which can be used to restore systems to a previous state in case of failure. Cloning allows for quick replication of VMs for backup or testing purposes. Virtual machines can be backed up and restored more easily compared to physical servers. Backup solutions can capture entire virtual environments, ensuring quick recovery in case of data loss or system failure.

    5. Increased security and isolation: Each virtual machine operates in its isolated environment, reducing the risk of one VM affecting others. This isolation enhances security by containing potential threats within a single VM. Virtualisation platforms often include advanced security features, such as granular access controls and monitoring tools, which help safeguard against unauthorised access and potential breaches.
