Virtualization is a technology that empowers you to create virtual versions of computing resources that are typically tied to physical hardware. By doing so, you can make more efficient use of your hardware by dividing its capabilities among multiple users or environments.

What is Virtualization?

Virtualization, in the context of computing, is a solution that allows multiple operating systems to run simultaneously on a single physical computer or server. This solution enables organizations to maximize the use of hardware and reduce costs while increasing efficiency.

Consider a scenario where an organization has multiple physical servers for dedicated functions like email, web hosting, and legacy application hosting, but every server only utilizes around 30% of its total capacity. By employing virtualization, the organization can create virtual machines that mimic the capabilities of these physical servers. These virtual machines can be consolidated onto a single physical server, allowing the organization to use its computing resources more efficiently.

From an organizational perspective, running multiple tasks simultaneously on a single server becomes complicated using traditional computing, primarily because each task requires its own operating system (OS) and software. 

This is where virtualization can play a significant role. Not only does it maximize hardware usage by distributing its capabilities across multiple environments, but it also helps lower power consumption and enhance system flexibility. Moreover, it supports more accessible backup and disaster recovery alongside simplified testing and development.

Why Use Virtualization?

There are several concrete reasons why organizations should opt for virtualization. These include:

  • Hardware utilization: With virtualization, organizations can more efficiently use existing hardware by consolidating multiple virtual machines onto a single physical server. This can increase hardware utilization rates, reducing the need for additional hardware and associated costs.
  • Cost savings: By consolidating multiple virtual machines onto a single physical server, the organization can reduce hardware and maintenance costs. It also helps to reduce power consumption and cooling requirements, resulting in significant cost savings over time.
  • Improved flexibility: As organizations gain the breadth to create multiple virtual machines, it results in greater flexibility to configure and manage computing resources to meet specific business needs.
  • Simplified testing and development: This technology provides a platform for testing and developing new applications and software without interfering with existing systems, enabling organizations to innovate and improve their technology without impacting daily operations.
