Data center virtualization separates compute resources from storage and networking resources in a data center. By doing so, organizations can improve efficiency and Agility by deploying and managing applications faster.
Data center virtualization also enables more efficient use of computing resources by pooling them together and allowing organizations to run multiple applications on the same infrastructure and dynamically move and resize them to meet business needs.
What Is Data Center Virtualization
Data center virtualization is also about abstracting the underlying infrastructure and physical servers from applications. It allows companies to consolidate their compute resources and manage them in a consistent way, reducing the cost of deploying and managing Virtual Machines (VMs) across different hypervisors or running multiple VMs on a single physical server.
However, there are differences between virtualization software — such as VMware vSphere and Microsoft Hyper-V that vendors use to create a hypervisor or kernel of the operating system and manage it all from one interface — and data center virtualization, which separates compute resources from storage and networking resources in a data center.
Virtualizing data centers involves separating applications from the underlying infrastructure. This layer allows you to run multiple applications on the same infrastructure, dynamically move and resize them to meet business needs, and consistently manage them.
The benefits of data center virtualization include:
- Improved efficiency and Agility.
- More efficient use of computes resources.
- The ability to consolidate your compute resources.
Data center virtualization is also a key ingredient in the cloud computing model.
Suppose you’re thinking about deploying a private cloud or moving to the public cloud. In that case, you’ll need to understand data center virtualization and how it can help you achieve your business goals.
Why Companies Should Virtualize Their Data Centers
In the early days of computing, business applications were hosted on individual servers. During this period, the number of applications and users increased, so did the need for more servers. Soon, organizations were using multiple servers to host a single application, and the data center was born.
As businesses continued to grow and their needs changed, they turned to virtualization to consolidate servers and reduce their total cost of ownership. Virtualization software, such as VMware vSphere (released in 2001) and Microsoft Hyper-V (released in 2008), is the technology used by most private cloud providers today, enabling organizations to create virtual machines or VMs — software versions of physical or “bare metal” servers — within a single server and operating system instance.
By virtualizing their data centers, businesses could run multiple applications on the same infrastructure and dynamically move and resize them to meet business needs. Virtualization also allowed companies to consolidate their compute resources and consistently manage them, reducing the cost of deploying and managing VMs across different hypervisors or running multiple VMs on a single physical server.
Today, data center virtualization is still a critical part of the cloud computing model. In order to move to the public cloud or even to deploy a private cloud, you need to understand data center virtualization and how it can help you achieve your business goals.
