VMware offers an array of solutions for virtual systems, but we focus only on vSphere in this article. Also, no security patches are necessary for the Controlling Layer components. Out of the box, vSphere offers many governance capabilities and organization can leverage transparent page sharing. One disadvantage is the steep learning curve for many users. Also, more initialization time is necessary because device drivers initialize in the hypervisor layer of the architecture.
Any corrupt code in this layer can cause the initialization to slow down, or even cause the server to hang or crash. Microsoft Hyper-V is capable of helping many companies build a private cloud, virtualize workloads, and scale public cloud services. Hyper-V is built on a microkernalized design, so the device drivers run and operate independently in the Controlling Layer.
These components are built into the Controlling Layer:. For most administrators who've worked with Microsoft products in the past, Hyper-V has an easier learning curve. Perhaps the best advantage is in how little effort is necessary to manage device drivers since new devices can be added without drivers—which means that a wide range of devices can be used with Hyper-V.
Any necessary device drivers are installed directly into the operating system that is running in the Controlling Layer. These drivers are then accessible by virtual machines to access the hardware. It takes Hyper-V just a few minutes to install and deploy new server roles in addition to the main virtualization role.
Also, since the Microsoft hypervisor code is only kB in size, initialization takes less time. In Hyper-V, there is a parent partition and any number of child partitions. The host OS runs in the parent partition. Each child partition is a VM that is a complete virtual computer, with a guest OS need not be Microsoft and programs running on it. The VMs use the same hardware resources as the host.
A single Hyper-V host can have many VMs created on it. Hyper-V allows you to use your physical hardware more effectively by running multiple workloads on a single machine. It lets you use fewer physical servers, thereby reducing hardware costs and saving space, power and cooling costs. With Hyper-V, you can set up and scale your own private cloud environment. Many organizations use Hyper-V to centralize the management of server farms.
This allows them to control their VMs efficiently and reduce the time spent on IT infrastructure management. Hyper-V includes multiple components that make up the Microsoft virtualization platform. These include:. With the installation of Hyper-V on a private cloud environment, organizations can be more flexible with their on-demand IT services and expand when required.
Hyper-V puts existing hardware to the maximum use, ultimately reducing costs and increasing efficiency. Having multiple instances of virtual servers minimizes the impact of sudden downtime , which means system availability increases and companies can improve business continuity.
Security depends on the application of Microsoft security updates, which requires all VMS to be taken offline or moved to a different node to avoid downtime. New guest operating systems that are supported by VMware include:. Academic research was performed to evaluate the performance of Hyper-V, VMware, and other solutions in a controlled laboratory setting, using methods of evaluation and testing guided by the scientific method. According to the authors of the resulting paper, "we conducted performance experiments using different scenarios on each virtualization approach supported by the latest versions of the mentioned hypervisors.
The results indicated that based on performance factors, Hyper-V outperformed VMware. Full insight into the results of each individual test performed by the researchers, their resarch methods, and results can be viewed here.
Data Source: TechNet. For additional information, we recommend the full overview written by Petri. Success in virtualization requires a strong knowledge of your business requirements, clear goals, and a hypervisor that facilitates ease of use.
The popularity of both vSphere and Hyper-V speaks to the products' quality and broad user bases. It can be natural to feel overwhelmed about selecting a hypervisor, which can be a decision that has an impact on your overall virtualization experience. Atlantech Online has extensive experience helping organizations of all sizes and experience levels achieve their virtualization goals. To speak with a virtualization expert today, click here.
