Which is better Hyper V or VMware

Any comparison between Microsoft Hyper-V and VMware vSphere takes into account a number of different aspects. First of all, their target customers and different models of the deployment function combination is not the same. The number of actual machine instances varies greatly with deployment requirements, which also lead to different infrastructure and configuration choices. Second, it is a matter of management, which is closely related to the size of the installation. In addition, we will consider a number of other issues, including cost, performance, scalability, and availability.

Target customers:

When it comes to high-end, large-volume virtualization customers, VMware still dominates. Various features of VMware, such as distributed resource scheduling (DRS), meet the needs of a large environment to run a large number of VM devices on a wide variety of resource requirements, while in another case we can only nod to Microsoft. If a small or medium sized business purchases Windows Server 2012, however, it makes no sense to purchase VMware vSphere to virtualize some specific functionality.

It is a difficult question to answer when it makes sense to use VMware. Hyper-V 2012 adds a number of new features to SMB 3.0, enabling even the smallest businesses to support highly accessible clusters using low-cost servers and commercially available SAS disk drives. The host-to-host VM replication capability for Hyper-V 2012 also provides an additional level of redundancy, which was not supported in previous versions. From this point of view, the duel between the two is drawn.

At the same time, VMware has a similar feature that USES the same Microsoft shadow copy service (VSS) behind the scenes. These and many other similarities make it problematic to compare the two products. In the end, their products perform well enough that users can adapt them to meet most of any virtualization needs.

Management tools:

At the low end of the scale, Microsoft provides users with basic tools on Hyper-V manager as an installable option for Windows Server 2012. The traditional management tool of VMware, VMware vSphere client is a free client that users must install on their PC. Both offer services that connect to remote hosts and allow users to manage any system in the network.

Some features are not available on the two product base management tools. The advantage of Microsoft's Hyper-V manager is that, for example, it can move in a virtual machine tool, type it in, and clone or copy the virtual machine tool. To use VMware, users must connect to the vCenter Server1 side to move in or clone a virtual machine application tool. However, out of respect for the hypervisor, the VMware vSphere client provides more information about the host server and the client virtual machine server. VMware scored one point in the comparison, thanks to a more detailed chart.

VMware offers vCenter Server for managing large installations, while Microsoft offers System Center 2012. The latest release of vCenter (version 5.1) adds a portfolio of web clients to manage users' VMware infrastructure from anywhere. Both VMware and Microsoft use Windows PowerSHEll (command line shell and scripting system management tool) to support automated management. VMware also adds a free command line tool called PowerCLI, which contains a long column of custom PowerShell cmdlet script files to manage the user's vSphere infrastructure.

Memory environment:

Does hypervisor support memory overallocation? Memory overallocation is a technique provided in vSphere that allows administrators to allocate more RAM capacity to a virtual machine than to a host. There have been many articles for and against this topic, but it is clear that allocating more resources than the physical requirements will increase the overall density of the virtual machine. Overallocation of memory in a production environment is appropriate for each institution. That said, in my opinion, when used in the right environment, this technology can provide important benefits.

Transparent page sharing:

Transparent page sharing is a way to achieve memory overallocation. With this technique, common code Shared between virtual machines is itself virtualized. For example, your VDI environment has 100 virtual machines running Windows XP. With transparent page sharing, RAM is not necessarily a major limiting factor for server desktop density. VMware stands out for this technology.

In the end, it can be seen that VMware still has an irreplaceable position in the virtualization field. Although Microsoft Hyper-V has been constantly improving in the virtualization field in recent years, and even surpassed VMware in some functions, VMware is better than 1 in terms of both user recognition and cost performance.
