Virtualization has become an essential part of modern-day businesses, and its popularity can be attributed to the long list of benefits it provides. This technology offers flexibility, cost-efficiency, on-demand scalability, reliability, and portability, making it an attractive option for businesses of all sizes. Essentially, hardware virtualization is made possible with the use of virtualization platforms, which help manage workloads in a virtual environment. Currently, the two major players who dominate the virtualization market are Hyper-V and VMware.

In this blog post, we’ll take a look at the main differences between VMware vSphere vs. Hyper-V, and help you determine which platform is best suited for your needs.

What Is Hyper-V?

Hyper-V is a type-1, native hypervisor designed by Microsoft. It allows for the creation and management of multiple virtualized versions of a computer, called virtual machines (VMs). Hyper-V provides a virtualization platform on which you can build IT infrastructure of any level of complexity. Each VM runs in its own isolated space, without interfering with the processes in other VMs.

Hyper-V supports multiple operating systems and is compatible with various hardware types. It provides a wide range of features, such as dynamic memory allocation, live migration, and virtual storage management. Hyper-V also has a robust security model, which allows for secure isolation between virtual machines.

What Is VMware vSphere?

VMware vSphere 8

VMware vSphere is a server virtualization platform created by VMware. It encompasses a set of virtualization products, which include the ESXi hypervisor, vSphere Client, VMware Workstation, vCenter, and others. All of these products combined constitute the VMware infrastructure, which enables centralized management of the created virtual environment.

VMware vSphere is compatible with a wide range of hardware and operating systems. It provides features such as resource pooling, high availability, and live migration. VMware also has a robust security model, with features such as virtual machine encryption, secure boot, and secure access control.

Comparing Hyper-V vs VMware: Which Virtualization Platform is Right for You?

Choosing the right virtualization platform can be a daunting task, especially when you have to decide between the two major players dominating the market – Hyper-V vs VMware. We’ll take a closer look at both platforms, and their unique features, advantages, and disadvantages, to help you determine which one is best suited for your business needs.

Architecture: How Hyper-V and VMware vSphere Differ

One of the primary differences between Hyper-V and VMware vSphere lies in their architecture. Let’s take a closer look at each platform’s structure:

Hyper-V Architecture

Hyper-V is a native hypervisor designed by Microsoft, which enables the creation and management of multiple virtual machines (VMs). Hyper-V exists in two modes:

The Hyper-V role, is an in-built Windows Server feature that can be enabled by a server administrator. • The standalone Microsoft product (also known as Hyper-V Server), with limited functionality and Hyper-V management components.

Hyper-V’s architecture is based on micro-kernelized hypervisors, where the host server (parent partition) provides direct access to hardware and computing resources (virtualization stack). VMs are isolated into logical units (partitions), including operating systems (OSes) and applications. Each Hyper-V environment can have only one parent partition, which should run a supported version of Windows Server. The parent partition can create multiple child partitions for hosting guest OSes. Child partitions can’t directly access hardware resources, but they can present a virtual view of the resources in the form of virtual devices. The communication between the parent and the child partitions is conducted via the VMBus, which lets you manage the requests directed to virtual devices. The parent partition also includes a Virtualization Service Provider (VSP), which enables the connection to the VMBus for managing device access requests from child partitions.

Hyper-V can host two types of OSes in child partitions: enlightened and unenlightened. The main difference is that the enlightened child partition has Hyper-V integration components and a Virtualization Service Client (VSC), which allows direct communication with the virtualization layer, avoiding device emulation. In contrast, the unenlightened child partition does not have the same components and simply emulates software.

VMware vSphere Architecture

VMware vSphere is a suite of virtualization products that allows you to build a computing platform. At the core of vSphere lies VMware ESXi, a type-1, native hypervisor used to manage host servers and run multiple guest VMs. ESXi enables direct access to the physical machine’s computing resources, which are shared by the VMs running in the system.

VMware ESXi requires a minimum amount of hardware resources and enables a small footprint of 70 MB. High performance of ESXi is ensured by VMkernel, which forms the basis of the virtualization process. VMkernel runs directly on hosts and provides a connection between VMs and the physical hardware.

To manage the VMware virtualization platform, other components of vSphere, such as VMware vSphere Client or VMware vCenter Server, are provided. They function as the management tools used for running ESXi hosts.

Management Tools Compared: VMware vCenter Server vs. System Centre Virtual Machine Manager

In the comparison between Hyper-V and VMware, it is important to consider the management tools that are essential for operating in any virtual environment. VMware and Hyper-V are both managed by different tools, namely VMware vCenter Server and Microsoft System Centre Virtual Machine Manager (SCVMM), respectively.

VMware vCenter Server is a centralized data management application that is used to manage VMware vSphere environments and build virtualized cloud infrastructures. It serves as a virtual machine manager that is installed on the primary server for monitoring the VMs running in the virtual platform. With this tool, you can view and control all ESXi hosts and host clusters from a single console, making management more streamlined.

On the other hand, SCVMM is a management tool designed by Microsoft for operating multiple VMs existing in the same environment. It comes in two versions: as an in-built feature of the Windows OS or as a stand-alone product. SCVMM allows you to create, control, and delete VMs. The tool manages the processes occurring in the VMs by providing access to necessary hardware resources, such as memory, drivers, storage, and others.

Storage Deployment: Comparing vSphere VMFS with Microsoft ReFS

Virtualization abstracts software from hardware and stores all VM data in a virtual disk file, which acts as a hard disk for the VM. Both vSphere and Hyper-V use virtual hard disks to store data, with vSphere using the VMDK format and Hyper-V using the VHD format.

Virtual disk files in the virtual environment are stored and organized through a file system. Both VMware and Microsoft have introduced their native file systems to manage data on a storage device.

VMware VMFS (Virtual Machine File System) is the clustered file system used for storage virtualization of the data in a virtualized environment. Multiple VMs can access and use a single VMFS volume simultaneously, reducing management overhead and

improving resource utilization. With VMFS, you can manage VMware ESXi hosts across the cluster, allowing you to add, migrate, or remove multiple hosts. VMFS uses on-disk locking to ensure that only one user or process can access data at a time, preventing data corruption.

In the Hyper-V environment, the equivalent solution is ReFS (Resilient File System), introduced as a built-in feature of Windows Server 2012. ReFS is based on the earlier file system NTFS and was designed to address modern data storage requirements and eliminate the issues existing in NTFS. ReFS allows users to access VM files directly from a host server and can detect and fix data corruptions promptly, with no volume downtime. ReFS also offers new features such as Block Cloning and Sparse VDL to speed up VM operations. However, Hyper-V’s clustering functionality is less flexible than that of VMware VMFS. While Hyper-V includes Cluster Shared Volume (CSV), its use is much more complex than in VMware VMFS.

Guest Operating System Services: VMware Tools vs Microsoft Integration Services

Virtualization technology has become an indispensable tool for businesses of all sizes that rely on efficient computing infrastructure. Both VMware and Hyper-V, two of the most widely used virtualization solutions, provide a range of tools and services for managing guest operating systems and ensuring seamless integration between the virtual and physical infrastructure. In this article, we will compare the services offered by VMware Tools and Microsoft Integration Services.

VMware Tools

VMware Tools is a set of drivers and utilities facilitating communication between the host and guest operating systems. VMware Tools include VMware Tools Services, VMware Device Drivers, VMware User Process, and VMware Tools Control Panel. By installing VMware Tools, you can enhance graphics performance, achieve high-level synchronization between the host and guest file systems, and enable shared access to files and folders within the virtual environment.

VMware Tools Services is the component that enables the communication between the host and guest operating systems. VMware User Process allows you to copy/paste text and drag/drop files between the host and guest operating systems, and VMware Device Drivers provides a set of drivers that can improve mouse operations, networking performance, and the quality of sound and graphics.

The VMware Tools Control Panel is a graphical interface that provides an overview of VMware Tools and enables users to configure them. By configuring VMware Tools, you can optimize their performance and ensure efficient management of VM data.

Microsoft Integration Services

Hyper-V provides the opportunity to install Microsoft Integration Services, which helps perform various tasks and solve recurring issues. The primary application of Hyper-V Integration Services, also known as SQL Server Integration Services (SSIS), is in data migration as it enables data integration and workflow optimization.

The SSIS Import/Export Wizard is a component of Microsoft Integration Services that allows users to create packages that move data from one point to another, without affecting its integrity. Moreover, you can easily edit and manage the created packages in the Business Intelligence Development Studio (BIDS) with the help of its user-friendly interface. Another exclusive feature of Hyper-V is the Server Integration Services Database Package (SSISDB) Upgrade Wizard, which enables the upgrading of a catalog database that stores and monitors all database packages in the system.

Snapshot Technology: Snapshots vs. Checkpoints

Snapshot technology is a powerful feature that enables you to capture a point-in-time copy of a VM and all the data it contains. Snapshots can be used to recover a VM to its original state in case of a failure or disaster. Both VMware and Hyper-V provide snapshot technology, but they work differently, and the terminology used is also different. VMware uses the term ‘snapshots,’ whereas in Hyper-V they are called ‘checkpoints.’

It is important for administrators working in a virtualized environment to understand the differences between snapshots and checkpoints, to improve memory space management. Snapshots in VMware are stored as a set of files in the same directory as other files that comprise a virtual machine, and are transient, meaning they are not persistent. On the other hand, Hyper-V checkpoints are stored on the host server and can be exported to another location. They are persistent and can be used for running snapshots in production.

Another important difference between VMware snapshots and Hyper-V checkpoints is that VMware can support up to 32 snapshots per VM, while Hyper-V can support up to 64 snapshots per VM. Additionally, changed blocks are identified on the file system level in VMware, while in Hyper-V, they are identified in each file of the file system.

Note that snapshots cannot be used instead of backups, as they are not suitable for long-term storage and can be lost if the VM’s virtual disk is damaged.

Workload Migration: vMotion vs. Live Migration

If you are working in a virtual environment, migrating workloads is essential. Luckily, both VMware and Hyper-V offer tools to make the migration process easier. However, it’s important to note that VMware vMotion and Hyper-V Live Migration are two separate tools.

If you’re using VMware vSphere, vMotion allows for seamless migration of workloads between servers with almost no downtime. This means that your virtual environment won’t be interrupted, and all applications will still be accessible. Plus, you can even schedule migrations to happen at specific times using the VMware vSphere Distributed Resource Scheduler.

On the other hand, Hyper-V Live Migration is designed to transfer a running virtual machine or application between physical hosts without causing downtime. However, Live Migration is more complex than vMotion. Before performing a migration with Live Migration, you’ll need to set up Microsoft Failover Clustering on all physical hosts and adjust network settings to ensure seamless data transfer.

Supported Operating Systems: VMware vSphere vs. Hyper-V

When it comes to virtualization, it’s important to consider which operating systems are supported by the platform you’re using. The guest OSes supported by VMware and Hyper-V can differ.

If you’re using VMware, you’ll have support for a wide range of operating systems, including Windows, Linux, Unix, Macintosh, and others. To see the full list of supported OSes, you can refer to the guest operating system installation guide.

On the other hand, Hyper-V has a more limited number of supported guest OSes. According to the official site, Hyper-V does support not only Windows, but also Linux, FreeBSD, SUSE, and other OSes.

It’s worth noting that VMware supports multiple versions of different operating systems, while Hyper-V emphasizes supporting Microsoft OS, the most widely used operating system in the world.

Pricing: VMware vSphere vs. Hyper-V

When it comes to pricing, both Hyper-V and VMware offer a free version of their virtualization platforms. This allows you to test the basic-level functionality of their products, but you won’t be able to fully test all of the components.

However, comparing the pricing policies of Hyper-V vs VMware can be tricky because VMware ESXi is licensed per socket (physical CPU), while Hyper-V has been licensed per core since 2016.

If you’re considering Hyper-V, Microsoft’s licensing model calculates the price based on the number of physical cores on the host. You’ll need to identify the total number of seats for which licenses are required, and each license is a two-core pack. It’s important to note that the minimum number of cores that can be licensed is four, so processors with one or two cores will still require four seats.

For VMware vSphere 8, licensing is done on a per-processor basis. This means that each server CPU should be assigned at least one processor license key.

To compare the pricing of Hyper-V vs VMware vSphere, take a look at the table below:

Hyper-VWindows Server DatacenterUS $6,155
Windows Server StandardUS $1069
Windows Server EssentialsUS $501
VMwareVMware vSphere StandardUS $1394
VMware vSphere Enterprise PlusUS $4,780

As you can see, Hyper-V’s pricing varies based on the edition of Windows Server being used, while VMware’s pricing is based on the version of vSphere being used.

When considering Hyper-V vs VMware vSphere, it’s important to take into account not just the pricing, but also the features and functionality that each platform offers.

Wrapping Up

both Hyper-V and VMware vSphere are great virtualization solutions that offer excellent features and benefits. When it comes to choosing between them, it ultimately depends on your specific needs and preferences.

If you’re looking for a cost-effective solution that’s easy to use and integrates well with Microsoft products, Hyper-V may be the best choice for you. On the other hand, if you require a more advanced, feature-rich solution that offers greater scalability and flexibility, VMware vSphere may be the better option.

At the end of the day, it’s essential to carefully evaluate your requirements and consider the pros and cons of each solution before making a decision. With the right choice, you can enjoy the benefits of virtualization and streamline your IT operations for optimal efficiency and performance.
