The Ultimate Comparison of vCenter vs vSphere

The Ultimate Comparison of vCenter vs vSphere

Reading Time: 4 minutes

In this post on, we will take a closer look at the vCenter vs vSphere ultimate comparison. VMware is a software company that creates multiple software products, especially for providing various virtualization solutions.

There are many cloud products, data center products, desktop products, etc. vSphere is a software package under the data center product. vSphere is like the Microsoft Office suite, which has a lot of software like MS Office, MS Excel, MS Access, etc.

Like Microsoft Office, vSphere is also a software package with many software components such as vCenter, ESXi, vSphere client, etc.

VMware vCenter Server is a centralized management app that grants you centrally managed virtual machines and ESXi hosts. The VMware vCenter Server is another part of the vSphere package.

There are two types of vCenter servers. vCenter Server is able to be installed on a Windows Server or Linux-based virtual machine. VMware will discontinue the Windows-based vCenter Server and release only Linux-based vCenter tools in the future.

What Is vSphere?

VMware vSphere is a cloud computing platform provided by VMware. VSphere encompasses several individual products and technologies to offer a complete virtualization infrastructure. VMware vSphere is not a separate software but a software package with several sub-components.

vSphere includes an updated version of vCenter Configuration Manager and Application Discovery Manager and vMotion for moving multiple virtual machines (VMs) simultaneously from one host server to another. VMware vSphere is a software package for virtualization solutions with many software components such as vCenter, VMware ESXi, vSphere client, and others.

VMware vSphere 7, the latest release, reportedly combines with VMware Tanzu to allow IT administrators to start Kubernetes workloads within an hour.

Key features of vSphere

VMware vSphere environment makes life easier for administrators, and here’s why:

  • You are able to create remote offices that can be managed without local IT administrators.
  • You can create an environment solely with your wishes. Alternatively, vSphere offers open-source environments (OpenStack VMware OpenStack).
  • Flexible management lets you create and manage multiple virtual machines at once.
  • The possibility of instant migration for uniform load distribution is uninterrupted.

What is vCenter Server?

When you look at the vSphere ESXi and vCenter Server, you compare the leading hypervisor to the solution management part. The vCenter Server provides the overall level of management and control for the vSphere product suite. The vCenter Server is the part that generally unlocks the enterprise features you get when you group multiple VMware ESXi hosts.

The vCenter Server is what makes this possible. With vCenter Server, you get access to the new HTML 5 vSphere Client part of the vCenter management interface. The vCenter interface is more powerful than the host interface included in the ESXi host. With the vCenter Server, you add your ESXi hosts to the management environment.

It allows you to manage the ESXi server and form a vSphere cluster centrally. In addition to centralized management, vCenter provides a central management point for backup solutions for interacting with all ESXi hosts from a single location.

Through vCenter, backup solutions can connect to all ESXi hosts and perform backups on virtual machines using the vCenter management interface.

Key features of vCenter

With VMware vCenter, it is certainly simpler and more convenient to operate the virtual machine:

  • The administrator can provide users access to vCenter Server instances after a single login, without subsequent authentication.
  • It is likely to extend and increase the launch of 35,000 virtual machines and up to 2,000 hosts with one example of vCenter Server.
  • Ability to start workflows necessary to eliminate problems due to timely reporting and automatic error correction.

The interaction difference between vSphere and vCenter

VMware vCenter centrally organizes ESXi virtual machines and hosts. The difference between vSphere and vCenter is that the vCenter Server is one of the components of the vSphere package. Nowadays, vCenter Server can be installed on Windows Server or Linux-based, but they promise to provide access only through the Linux kernel in the future.

VCenter Server lets you control access permissions, track average VM performance, and configure notifications. Additionally, suppose a company or enterprise needs additional features such as VMware Update Manager, vMotion, VMware High Availability, VMware Distributed Resource Scheduler (DRS), etc.

Consequently, we can summarize the vCenter Server vs. vSphere: vSphere is a complete VMware virtualization platform whose primary purpose is to virtualize and optimize essential physical hardware resources. Having that said, VMware vSphere also provides virtual resource pools for the data center.

The vCenter Server, on the other hand, is an integral part of vSphere, which increases the abilities of the administrator and the company as a whole incredible.

VMware vSphere vs. vCenter vs. ESXi

Let’s compare these 2 with VMware ESXi hypervisor and see how these technologies complement each other and work together to create the virtualization infrastructure that companies need.

ESXi is a hypervisor installed on a physical machine. vCenter Server is a VMs management platform. When working in a small virtualization environment, the vSphere client will be sufficient to maintain and manage virtual machines hosted on multiple ESXi servers.

Despite the fact that your environment is growing in size, and you need advanced features to handle your multiple ESXi servers, the more progressive vCenter will let you control access permissions, track performance, and, for instance, clone an existing virtual machine. vCenter is still managed via the vSphere client to simplify the process for administrators.


Most physical machines are underused, at best operating at 15% of their capacity, leaving 85% unused. vSphere comes with a solution to this problem, allowing us to use most hardware.

Multiple instances of virtual machines running different operating systems and applications can be installed on a single physical machine; your entire infrastructure can be virtualized, even if it consists of a number of connected physical devices and storage.

And with that comes an increased amount of data generated, and you probably want to secure that data. Although VMs are a more secure way to store your data, they are not 100% bulletproof.

The VMware vSphere and vCenter server are essential parts of the VMware architecture. Understanding where each one fits into the VMware mix is vital to understanding how the environment is structured and configured and what you need to build a VMware infrastructure.

We at VMware-ESXi are looking forward to more to come, and not just vSphere vs vCenter comparison, but ESXi as well.
