In general, majority of data restore systems often specify their ability to restore data to only the computing systems with similar or the same software running on them (i.e., environment like operating system, applications, and others). But the case of Base Metal restore is totally different and more unique as it is a repair and restoration technique designed to restore data to a computing system with entirely different hardware and software environment. So, the restoration process is coined “Bare Metal”, which means that the process does not need any requirement from the computing system where the data backup was done for it to restore the data.

Some Difference between Bare Metals and Disk Image Restore
Though, Bare Metal and Disk image restores work with similar process with each other, there are differences that exist between them. While Bare Metal involved installation of operating system, applications and component of data in the image file, Disk Image Restore only requires the installation of the restoration software and a copy of the disk image installed in the backed up computing system. With the help of Bare Metal imaging applications, the process of bare metal restore will be made easier. There is always replication of images of software components as well as the data to the new disk that were present at the time of backup through snapshots. This normally makes it easy for the data and the images to be restored using Bare Metal. The entire file systems in the disk images as well as disk partitions are copied using Linux Booth CD. There is also creation of new partition with either the same or larger size disk image, which resulted from the backup. Some servers support Bare Metal restores, and users can make use of such Bare Metal enabled servers to restore or recover their system in to a HyperV virtual machine.

Indeed, just with one single restore process, the entire computing system can be restored to the last known good state with the help of Bare Metal systems. This wonderful system is great and useful for recovering of data from the system during a disaster. This is made possible owing to the fact that the disk image can be useful for recreating the whole system at completely new geo-location with new hardware, using online application access. The restoration process involved in Bare Metal has been referred to as an art instead of a science, as it differs in the implementation from other system restore software. Not all online backup providers have Bare Metal services. Asigra is a powerful cloud backup software that has the capability to provide Bare Metal restore services.

Before starting your restoration using Bare Metal, you must ensure that the configuration of your system is supported by bare metal as the storage configurations of the servers may not be the same. So, confirm whether the basic partition table type of your system is supported by Bare Metal before going ahead to make use of it for your system data restore.

Virtualization has some basic characteristics which help organizations to reduce hardware investment, operating cost, maintenance charges, and consumption of energy. It improves performance of system, as well as capability to recover data in disaster. Virtualization plays an important role in the growth of cloud computing.

Abstraction is important for cloud computing; therefore, virtualization separates applications as well as operating system from underlying machines. Decoupled procedure makes them able to travel across clusters, data centers, and servers. Side by side, virtualization brings together memory, resources and storage into particular virtual environment, and makes it easy to share applications and computing capacity through cloud.

Infrastructure Management
As far as cloud computing is concerned, it is linked with notable features. Some of familiar characteristics are as follows:

Scalability
Automation
IT Management
Agility
On-demand Delivery

Virtualization is recognized as primary source to help with the growth of cloud computing. On the other hand, the cloud offers a variety of benefits to virtual environment. When resources are librated and organized in virtual settings, they are dispersed and provisioned as needed. The cloud offers on-demand access, automated delivery and flexibility to particular resources and accommodates growth requirements. As a result, complexity and cost are reduced; and resources can be best utilized and extra attention can be directed towards business operations.

Growth of Non-Virtual Clouds
It is a fact that the cloud does not need virtualization to flourish; however, pairing of these two help in harvesting maximum benefits easily. It is the basic reason why the cloud platform is assisted through hypervisors like Hyper-V, as well as VMware Sphere. Moreover, there are a variety of technologies which are targeting to authorize the cloud to grow without assistance of virtualization any more.

Open source community has presented CoreOS as simple and easy to use operating system. It is based on Linux Kernel, which is familiar to may around the world. Services which are not important are stripped and Linux allocation makes use of particular containers to deliver security, performance and dependability advantages of virtual machines by using similar abstraction parts for which virtualization is renowned for. There is no use of hypervisor to get maximum advantage. Conversely, CoreOS assures nominal performance operating cost, as well as capability to strap up the cloud power by utilizing a few machines only.

One more open source alternative is Docker. It is best for those who are concerned to tap into cloud with no virtualization hassle. It is a particular type of tool, planned to containerize applications in an environment (Linux) without the need to virtualize the whole operating system. Cloud deployment is given power from Docker to enable the delivery of processes, tasks and application easy across a single physical machine or group of virtual machines. It works flawlessly with system CoreOS and improves the efficiency, speed and flexibility of available containers, as well as their significant applications.

If your organization is getting benefit from virtual environment, it means you have taken initiative for an infrastructure (cloud based) for an easy conversion. Though virtualization administration come with their own challenges, technologies such as CoreOS and Docker can be adopted as alternatives.
