BN208 Networked Applications | Virtualization Technology Develop

ng the data into the physical disk storage unit or the hard drive of the computer. Likewise, virtualization strategies can be connected to other IT framework layers - including operating system, networks, server hardware and network [5]. With the implementation of the virtualization technology a physical layer is established between the network hardware, storage unit and the different application running on the machine. The resource can be pooled and managed by the administration with the application of the virtualization technology and help the IT infrastructure of the organization to become more responsive and dynamic in nature and thus becoming cost efficient.

Virtualization is a piece of the IT framework for a considerable length of time, the VMware conveyed the advantages of virtualization to industry-standard x86-based stages, which now frame the larger part of desktop, tablet and server shipments. A key advantage of virtualization is the capacity to run numerous working frameworks on a solitary physical framework and offer the fundamental equipment assets known as parceling [2]. Today, virtualization can apply to a scope of framework layers, including equipment level virtualization, working framework level virtualization, and abnormal state dialect virtual machines. Equipment level virtualization was spearheaded on IBM centralized servers and the Unix/RISC framework merchants started with equipment construct dividing abilities before moving in light of programming based apportioning

Virtual machines

With the application of the virtualization technology the operating system and the application becomes hardware independent and it can be provisioned for any system. The virtualization of a system can help to manage the operating system and its application by encapsulating them as a single unit and deploying it into the virtual machine. For the creation of the virtual machine two types of approaches are applied using the VMware or software based partitioning which includes virtualization of the operating system and virtualization of the hardware resources [8]. A partitioning service is offered by the application of hosted service and for supporting the different configuration used by the hardware to run the virtual machine. The hypervisor architecture is also used for the installation of the virtual machine and running it on the same hardware platform. Since it has guide access to the equipment assets, a hypervisor is more productive than facilitated designs, empowering more noteworthy adaptability, power and execution.

The virtual machine is created by representing a physical machine using a software application. A set of virtual hardware devices are used for the creation of the virtual machine and utilizing the virtual hardware the application and the operating system can be installed [1]. The VMWare application can be utilized for the virtualization of the hardware resources and it contains advanced features like multiprocessing and memory management.

Different challenges faced by an organization can be mitigated with the application of virtualization such as:

Containment and consolidation of the server-

Dispensing with 'server sprawl' by means of arrangement of frameworks such as virtual machines for running it securely and move straightforwardly crosswise over shared equipment, and increment server usage rates from 5-15% to 60-80%.

Testing and optimizing the system-

Testing and rapidly provisioning the test for the deployment of the servers and reusing the system resources for decreasing the IT cost in the organization. Different standards are required to be applied for the deployment of the server and enhance the collaboration of the developer for the deployment of the server [7]. The preconfigured systems can be used and the system can be virtualized for optimizing the framework.

Continuity in the business-

The cost of the server virtualization is less and the complexity is also less and help the organization to utilize its resources efficiently. The virtualization helps in higher availability of the resources and helps to meet the growing demand of the organization. It also helps to replicate the files and restore the files residing in the targeted server for minimizing the downtime and maintain continuity in the business.

Desktop enterprise-

The unmanaged PCs are required to be secured with the application of the server visualization technology. The security policy of the end users are required to be analyzed and applier for creation of the virtual machines.

Architecture of Virtual machines

The hypervisors are designed to tightly couple the operating system and the VMware Infrastructure virtualizes the whole IT framework including servers, stockpiling and systems. It totals these heterogeneous assets and presents a basic and uniform arrangement of components in the virtual condition. With VMware Infrastructure, IT assets can be overseen like a common utility and progressively provisioned to various specialty units and ventures without agonizing over the hidden equipment contrasts and confinements [9]. The architecture of the virtual machine consists of a simple virtual elements and they can be used for the development of a virtual data center. The virtual infrastructure client can also be used for allowing the network administrator to connect with the system remotely and a standard interface can be used for deployment of the virtual machines.

Protocols

There are different protocols that can be used for the development of the virtual service and deployment of the virtual machines. The protocol containing the IPv4 and the IPv6 address and a range of IP address can be assigned for associating the profile and controlling the network of the virtual machines. There are different protocols that can be applied for the designing the architecture of the virtual machine and configuring it to balance the load of the current infrastructure of the organization [1]. The protocols are also used for the management of the virtual network and ensuring the security policy of the organization. The virtual switch can also be used and different VLAN can be used for interconnecting the network devices. The virtual machine has different Mac address and thus the Mac address can be linked with the layer 2 switch for bounding the connection. The

Techniques 

Different techniques can be applied for the virtualization of machine like consolidation of the server, para virtualization. The virtualization of the operating system can be done by the installing an application such as VMWare or virtual box in the host operating system and assigning host hardware to the virtual machine installed using the application program. Running on this working framework is a virtualization application which executes similarly as whatever other application, for example, a word processor or spreadsheet would keep running on the framework [2]. It is inside this virtualization application that at least one virtual machines are made to run the visitor working frameworks on the host PC. The virtualization application is in charge of beginning, ceasing and dealing with each virtual machine and basically controlling access to physical equipment assets for the benefit of the individual virtual machines. The virtualization application likewise takes part in a procedure known as double revamping which includes examining the guideline stream of the executing visitor framework and supplanting any special directions with safe imitations [6]. This has the impact of making the visitor framework think it is running specifically on the framework equipment, instead of in a virtual machine inside an application.

Framework for NAM

A complex infrastructure is used for the management of the network application it focuses on the security of the network framework and the main components considered for the development of the architectural design of the framework using the virtual machine is the optimization of the network [9]. The application of the network framework solution is addressed by the NAM and the optimization issues raised during the deployment of the solution are addressed using the application delivery controller and monitoring the performance of the network application.

The application delivery controller analyzes the load on the server and uses a load balancer for controlling the delivery of the network load. The load balancer redirects the network traffic into different channels and increases the efficiency of the virtual machines.

The monitoring of the performance is done to analyze the performance of the application installed in the virtual machines and the performance of the network, operating system and the devices installed in the network.
