Difference between Vmware ESX and Vmware ESXi

VMware ESX and VMware ESXi are two different types of virtualization software from VMware. Both offer great features and benefits, but there are some key differences between them that you should be aware of before making a decision about which one is right for your organization. In this post, we’ll take a closer look at those differences and help you decide which one is the best fit for your needs.

What is Vmware ESX?

Vmware ESX is a bare-metal hypervisor that runs on commodity x86 servers. It is used to create virtual machines (VMs) that can run on a physical server. VMs are isolated from each other and can share resources, such as memory and CPU, with the hypervisor. Vmware ESX is used in enterprise environments to consolidate server workloads, improve performance and reduce costs. It can also be used to create test and development environments, isolate applications and ensure business continuity. Vmware ESX is a powerful tool that can help organizations to optimize their IT infrastructure.

What is Vmware ESXi?

Vmware ESXi is a type of hypervisor that can be installed on a physical server. It essentially turns the physical server into a virtual machine, or “VM.” This allows you to run multiple VMs on a single physical server, which can be very useful if you need to consolidate multiple servers into one. Vmware ESXi is a popular choice for many organizations because it is very reliable and easy to manage. However, it is important to note that Vmware ESXi is not free – you will need to purchase a license in order to use it.

Difference between Vmware ESX and Vmware ESXi

Vmware ESX and Vmware ESXi are two different types of Vmware products. Vmware ESXi is the newer product and is a type 1 hypervisor that can be installed directly on bare metal hardware. Vmware ESX, on the other hand, is a type 2 hypervisor that must be installed on top of an existing operating system. Vmware ESXi is more popular because it is more efficient and has a smaller footprint. Vmware ESX requires more resources because it includes a full operating system. Vmware ESXi can run on less powerful hardware, making it more suitable for small businesses. Vmware ESX can only be used with Vmware vSphere, while Vmware ESXi can be used with other Vmware products such as Vmware Workstation and Vmware Player.


While VMware ESX and VMware ESXi are both virtualization products, they have some key differences. In particular, VMware ESX is a more full-featured product that includes features like clustering and VMotion, while VMware ESXi is a scaled-down version that is designed for smaller businesses or organizations.
