Virtualization – Setting a Trend beyond Reality

Introduction:

There are always two types of things in this world. Ones that exist naturally and the others that can be created artificially. In daily life, we come across many such products that are not real and we say that any such thing, which is far from reality, is virtual. In a world of computer and information technology, virtualization refers to the creation of virtual versions of things such as operating systems, hardware devices or network resources etc. A very good example of virtualization in computer science is when we divide our hard disk into different partitions during Windows installation. We know that a hard disk is an actual physical device but the partitions that we create are not real rather they are purely virtual. Similarly, when we create different folders on our drives, then this type of partition is also virtual. Now let us try to look deeply into the virtualization technology.

Working of Virtualization:

Virtualization works by creating multiple virtual machines (VMs) on a single physical machine. These virtual machines share common resources that are provided to the actual physical machine but each virtual machine have its own environment and while using any of the VMs we get an illusion of working on a completely independent new machine. However, the detailed working of virtualization depends upon which type of virtualization do we want to use.

Types of Virtualization:

Based upon the working and architecture, virtualization can be divided into the following two types:

➢      Bare Metal Virtualization- It is that kind of virtualization in which a hypervisor communicates directly with hardware resources without the need of installing a separate guest operating system. It is an efficient type of virtualization but its drawback is that the hypervisor has limited number of hardware drivers preinstalled on it so it can communicate with only a small number of hardware resources.

➢      Hosted Virtualization- In case of hosted virtualization, we have a separate guest operating system installed over the host operating system. This kind of virtualization resolves the hardware compatibility issues that are present in bare metal virtualization but its drawback is that it is not as much faster as bare metal virtualization because the guest OS cannot communicate directly with the hardware resources due to the presence of underlying host OS.

Advantages of Virtualization:

The advantages of virtualization are listed below:

●       Reduction in workload

●       Cost effectiveness

●       Faster deployment of resources

●       Low energy consumption

●       Efficient resource utilization

●       Fast data recovery

Disadvantages of Virtualization:

The disadvantages of virtualization are listed below:

●       It creates security issues

●       Limited availability

●       Lesser scalability

●       More time consumption

●       Complex trouble shooting

StarWind Hyper-converged Appliance:

StarWind HyperConverged Appliance is a software based hyper-converged platform, which is used to minimize application downtime. All the hyper convergence activities are monitored and managed on one single console. This appliance provides a proactive support, which monitors your cluster 24/7 in order to look for any defects, and if any defect is found, it removes it even before things go wrong any further.

The main features of StarWind HyperConverged Appliance are listed below:

●       StarWind proactive support

●       Server Message Block (SMB3) support

●       Network File System (NFS) support

●       Storage Management Initiative Support

●       Data Locality

●       Commodity hardware

This appliance comes in the following three models: All flash model, hybrid model and disk model.

Conclusion:

With each passing day, the virtualization technology is becoming more and more common and the software experts are trying their level best to enhance the performance of virtualization so that one day the benefits of virtualization can match the benefits of the real versions of different resources or even surpass them. Therefore, we can expect that a day will come when virtualization will be considered more important as compared to reality and that day will come eventually.
