Which of the following are benefits of virtualization select all that apply?
You'll spend less time maintaining the hardware and IT infrastructure when you have fewer servers. Instead of applying updates server-by-server, you can install, update, and maintain the environment for all VMs in the virtual environment on one server. Your team will be more efficient and productive if you spend less time maintaining equipment. Show
IT teams also use virtualization to solve complex, nuanced technical issues in the cloud. Since data is always available in a virtual server, IT doesn’t have to worry about data recovery from crashed or corrupted devices. Development and Testing Virtualized environments are segmented into virtual machines that developers can quickly spin up without affecting the production environment. Developers can also quickly clone a virtual machine and run tests on it. For example, a developer can clone the virtual machine, apply a new software patch, test the environment, and then pull it into the production application. This process speeds up application development. Sustainability Virtualization improves sustainability by cutting the number of physical servers and the amount of power you consume. This decrease significantly reduces the carbon footprint of the data center. Cost-Effectiveness Virtualization is a great way to cut expenses. If you store data on virtual servers or clouds, you won't have to buy physical hardware or systems. You can therefore reduce your waste, electricity, and maintenance costs. Additionally, virtualization saves you a lot of server space, which you can then use to improve operations. Virtualization is the creation of a virtual -- rather than actual -- version of something, such as an operating system (OS), a server, a storage device or network resources. Virtualization uses software that simulates hardware functionality to create a virtual system. This practice allows IT organizations to operate multiple operating systems, more than one virtual system and various applications on a single server. The benefits of virtualization include greater efficiencies and economies of scale. OS virtualization is the use of software to allow a piece of hardware to run multiple operating system images at the same time. The technology got its start on mainframes decades ago, allowing administrators to avoid wasting expensive processing power. How virtualization worksVirtualization describes a technology in which an application, guest OS or data storage is abstracted away from the true underlying hardware or software. A key use of virtualization technology is server virtualization, which uses a software layer -- called a hypervisor Hypervisors take the physical resources and separate them so they can be utilized by the virtual environment. They can sit on top of an OS or they can be directly installed onto the hardware. The latter is how most enterprises virtualize their systems. The Xen hypervisor is an open source software program that is responsible for managing the low-level interactions that occur between virtual machines (VMs) and the physical hardware. In other words, the Xen hypervisor enables the simultaneous creation, execution and management of various virtual machines in one physical environment. With the help of the hypervisor, the guest OS, normally interacting with true hardware, is now doing so with a software emulation of that hardware; often, the guest OS has no idea it's on virtualized hardware. While the performance of this virtual system is not equal to the performance of the operating system running on true hardware, the concept of virtualization works because most guest operating systems and applications don't need the full use of the underlying hardware. This allows for greater flexibility, control and isolation by removing the dependency on a given hardware platform. While initially meant for server virtualization, the concept of virtualization has spread to applications, networks, data and desktops. A side-by-side view of a traditional versus a virtual architectureThe virtualization process follows the steps listed below:
The virtual environment is often referred to as a guest machine or virtual machine. The VM acts like a single data file that can be transferred from one computer to another and opened in both; it is expected to perform the same way on every computer. Types of virtualizationYou probably know a little about virtualization if you have ever divided your hard drive into different partitions. A partition is the logical division of a hard disk drive to create, in effect, two separate hard drives. There are six areas of IT where virtualization is making headway:
Virtualization can be viewed as part of an overall trend in enterprise IT that includes autonomic computing, a scenario in which the IT environment will be able to manage itself based on perceived activity, and utility computing, in which computer processing power is seen as a utility that clients can pay for only as needed. The usual goal of virtualization is to centralize administrative tasks while improving scalability and workloads. Advantages of virtualizationThe advantages of utilizing a virtualized environment include the following:
Benefits of virtualizationVirtualization provides companies with the benefit of maximizing their output. Additional benefit for both businesses and data centers include the following:
Limitations of virtualizationBefore converting to a virtualized environment, it is important to consider the various upfront costs. The necessary investment in virtualization software, as well as hardware that might be required to make the virtualization possible, can be costly. If the existing infrastructure is more than five years old, an initial renewal budget will have to be considered. Fortunately, many businesses have the capacity to accommodate virtualization without spending large amounts of cash. Furthermore, the costs can be offset by collaborating with a managed service provider that provides monthly leasing or purchase options. There are also software licensing considerations that must be considered when creating a virtualized environment. Companies must ensure that they have a clear understanding of how their vendors view software use within a virtualized environment. This is becoming less of a limitation as more software providers adapt to the increased use of virtualization. Converting to virtualization takes time and may come with a learning curve. Implementing and controlling a virtualized environment demands each IT staff member to be trained and possess expertise in virtualization. Furthermore, some applications do not adapt well when brought into a virtual environment. The IT staff will need to be prepared to face these challenges and should address them prior to converting. There are also security risks involved with virtualization. Data is crucial to the success of a business and, therefore, is a common target for attacks. The chances of experiencing a data breach significantly increase while using virtualization. Finally, in a virtual environment, users lose control of what they can do because there are several links that must collaborate to perform the same task. If any part is not working, then the entire operation will fail. Which of the following are benefits of virtualization?Key benefits include:. Greater IT efficiencies.. Reduced operating costs..
