Case Study On Virtualization

Virtualization is a combination of software and hardware engineering that creates Virtual Machines (VMs) - an abstraction of the computer hardware that allows a single machine to act as if it were many machines, or a computer that does not physically exist as a piece of hardware. The hardware that is seen by the operating system is emulated in an effort to separate the physical hardware from operating system. This allows the virtual machine to be moved and hosted on any machine independent of hardware. Virtualization technology is possibly the single most important issue in IT and has started a top to bottom overhaul of the computing industry which is why many companies around the world have are using its softwares to enhance their business opportunities.

Cloud computing was a completely new term a short 9 years ago, in 2007. The basis of this technology is to move the workload of IT activities away from an organization, and to one or more third parties that have resources dedicated to processing such things. These can be, but are not limited to, networking, storage, software systems, and applications. Rather than having to create and maintain their own expensive datacenters, companies can pay a fee to use someone else’s. This makes growing businesses extremely flexible, as they can easily gain or remove storage space per their needs. Being able to purchase the use of online storage space is known as “hardware as a service,” or, more simply, “virtualization.” Being able to purchase the use of online software is known as “software as a service.” Both are very powerful tools that allow the minimization of a company’s IT budget.

To begin our IT solution, our company will look at the center point of all technology, which is our on-site data center. In the data center we have 2 physical servers, which are rack mounted with our uninterruptable power supply (UPS). This area also has its own dedicated A/C units. Our servers are designed for virtualization, which means multiple virtual servers can run on one server. These 2 servers also mirror each other and provide an on-site backup. There will be a fiber channel backbone between the 2 physical servers so data can be sent between them as needed. These 2 servers are Intel E 7450 zion, 6 core, 2.4GHz processors with 128GB memory and the operating system is VMware ESXi version 3.5 with 5 300GB 15K RPM drives which give approximately 1.2TB of total disk space. It also includes 4GB network cards with VMware virtual center version 2.5. Also, our company will have a 3 year 24/7 onsite support.

Virtualization also minimizes the cost of maintaining a datacenter by reducing energy cost, minimizing server sprawl and eliminating under utilization. As BMG embarks on their expansion projects, new virtual machines can be deployed quickly to accommodate the additional capacity required to grow their infrastructure dynamically without expending an enormous amount of capital.

As experts, they are reliable and take all business needs seriously and at the same time recommend the perfect solution for each client. Some of Marathon’s services include backup and disaster recovery, proactive monitoring and maintenance, remote Help Desk, onsite/offsite data storage solutions, installing/maintaining network security, firewall management, network maintenance, VOIP system maintenance, and server administration. As well, Marathon offers virtualization and Cloud Computing because the traditional server-desktop infrastructure although still valuable in today’s businesses, the changeover to virtualization is quickly approaching (marathonconsulting.com). As a result, the demand from many software vendors is to have a single server for their application as this ensures that operations are at peak performance. However, the problem is with multiple applications, they require isolation, and the infrastructure grows unnecessarily and by providing this service, virtualization and Cloud Computing make sense and Marathon provides this solution.

Network Based Virtualization is abstract storage of data applications from the host machine. This is well achieved through fibre channels connection between the machines and the servers running virtualization. The respective operating systems on the separate machines are not a factor to consider as they work independently. For it to achieve its expectations, the following services must be provided as below:

This virtualization service will reduce cost and the company will have reduction in server related capital investment by 70% and a reduction in operational cost by 30% to 40% compared to the physical server.( Accenture_Client_Success_Telstra_Virtualization)

Is the business at first full structure virtualization suite that grants endeavors and private endeavors get a kick out of the chance to change, regulate and propel their IT systems the system through virtualization. VMware Infrastructure passes on thorough virtualization, organization, resource headway, application openness and operational robotization capacities and limits in an arranged advancing.

In this work, it is assumed that there is a SaaS provider who owns a private data center which comprise a finite number of local servers which implements virtualization concepts to run user jobs. The SaaS provider is assumed to

Large corporations might choose to consolidate their IT system in one virtualized (and very expensive) server farm saving on hardware, support and maintenance costs over time.

Sytox Systems is an enterprise company that uses Cloud Computing as its main market front to obtain market share and equity value. In this company it has many different product offerings in virtualization software such as desktop and client applications to allow users to work from any location. This can be at home, at their child’s school, and even at a doctor’s office. It also has multiple hardware appliances which it creates and this manufacturing environment uses many different tools to access its on-time shipment details, return material authorization information, and

Storage virtualization is the pooling of physical storage from multiple network storage devices into what appears to be a single storage device that is managed from a central console. Storage virtualization is commonly used in storage area networks (SANs). Server virtualization is the masking of server resources (including the number and identity of individual physical servers, processors, and operating systems) from server users. The intention is to spare the user from having to understand and manage complicated details of server resources while increasing resource sharing and utilization and maintaining the capacity to expand later.

When a user want to use the services provided by cloud, its request is placed in the form of virtual machines in datacenter on currently active physical machine fulfilling the requirements specified by the user in such

This paper refers to the features of Virtual Machines and Virtual Machines Monitors describing the performance and challenges as well as mechanisms such as fault tolerance, high availability and v-motion. Main theme depicts that modern servers are designed sufficiently powerful to use virtualization into many smaller virtual machines (VMs), each running a separate operating system instance [1]. Numerous systems have been designed to get virtualization by utilizing the storage resources like SAN and processing & memory resources Like Servers and network infrastructure to build a cluster of failover servers [2].

Technology is one aspect of business that can universally enhance any company’s capabilities and add resources to offer a positive impact on the bottom line. However, information technology comes with its own implementation barriers that can complicate matters when making IT investments with an expectation to generate a return on that investment. The biggest impact of virtualization in cost structures is the radical change in how technology is implemented and paid for. Previously, any new technology could require a capital investment, lead times for setup and training, and continuing overhead in the form of support and
