Virtualization is a way to create systems that are less complex subsets of the division of systems into more manageable devices. In addition, this measure can give more security to the system, network and applications, as it isolates potentially vulnerable subsystems underlying systems and other virtual platforms.

The concept of virtualization includes all layers of the platform – from applications and operating systems components, processors and interconnections of the platform. But let’s stick to the storage devices and dedicated servers, because these environments are the most active market for virtualization.

An essential tool for all this virtualization work, is the Storage, which is a site designed and suitable for data storage.

Storage virtualization is the process of consolidating multiple physical devices from different manufacturers and rearrange them in clusters, virtual and logical, or storage units. These units are presented to the operating system for use by applications and end users.

Networked storage allows connectivity between all servers and storage devices, and also increases the capacity of organizations to migrate their data. Networked storage can reduce the costs of information processing, by increasing the sharing of devices and capabilities, as well as through more efficient communications.

For example, a virtual storage pool can be created by using the physical disks faster in order to optimize performance for a mission critical application, while protecting the user and the application details of hardware implementation. There are many technologies of “virtualization” of storage that have evolved, including solutions for internal and external bandwidth (in-band and out-band) based storage and hosting.

First of all, you must first go for the Virtualization – need to virtualize some applications and the company gets the benefits. Usually at this stage, about 30% of virtualized applications.To go further there is the idea that you need to virtualize not only the usual basic applications, but also critical applications – e-mail servers, and databases. Virtualization critical applications – is the second step of the model of IT as a service.

The transition to private cloud hosting

The third step is a transition to private cloud.The first two steps – this is the optimization of IT services. We can create a pool of resources, implement load balancing between resources and a process of automation.

In the transition to private cloud, you get other opportunities.You can create self-service portal. For example, you can choose a specific application and pay for on-demand resource.

Businesses can claim a certain level of IT as an agreement on the service provided (SLA) and this can be done with the clouds.

What is the valuable for the company is a constant IT solutions, services based on SLA, the payment on demand, moving applications within the clouds. VMWARE guarantees the full compatibility between your private cloud and external clouds.

The result is a new IT landscape, we have a large number of devices, the client may need the access from anywhere in the world and this access must be secure. Will be required to support a large number of applications.

Applications and users can work within a cloud – within its own data center. The task of IT is to combine them all together and you have complete control over all of this.

To understand the Infrastructure of Information Technology Services and Virtualization, identify and create solutions according to need and size, there are areas like Storage Backup, IP telephony, Wireless Network, Active Network Equipment, Structured Cabling and Optical Networks, and as well as Infrastructure of Virtualization, you need to be familiar with.

Storage Backup:

The Information Technology environments today are complex, and many organizations find that the volume of data is ever increasing, as well as the requirements for service levels, compliance, and obviously the cost for managing this structure.

Associated with these factors, there are the limited human resources and lack of flexibility of conventional technologies of data storage, which cannot adapt to the new requirements that arise every day.

In contrast, the technology users require solutions that are simple to use and advanced features that enable the organization work faster in their processes, with immediate access to information and, consequently, a decrease in response times for its demands.

The consolidation of data storage through the use of specific devices for this purpose, dramatically improves the operations in IT environments. Make data easier to manage, ensures an easy way to share information between applications with high availability and easy expansion without disruption of services.

Consolidation not only simplifies complex environments, but also optimizes the use of storage devices and increasing productivity, reducing the Total Cost of Ownership (TCO).

The use of advanced software makes it easier to meet requirements for service levels by increasing its efficiency. User-friendly tools, working through the storage infrastructure help you to use best practices.

IP telephony:

The concept of IP convergence, which is the unification of various telecommunications systems (voice, data, images, signs) on the network data communication, IP telephony is in its more direct application.

The benefits of converting voice, an analog signal converted into packets for transmission over data networks, have been known for over a decade through the use of VoIP. This initial application was aimed solely for reducing costs through the utilization of links WAN charged by a fixed value, exempting organizations cover the value of long-distance charges, levied on demand.

The same concept has recently been brought to the internal networks. Other benefits, however, began to be exploited. Meet a few:

• Reduced total cost of ownership (TCO) by using the same infrastructure of data communication for voice services;
• Reduced costs of connections, not only between offices of the same company, but also for the places where these offices are located;
• Increased productivity through the use of applications that take advantage of both worlds: data and voice. You can, for example, create collaborative environments in real time between people geographically distant. Another example is the integration between e-mail services and voice mail.
• Mobility, since the extension is no longer a corporate device connected to a PBX port and becomes an IP device connected anywhere in the world. Just have a network of broadband access.

Wireless Network:

The constant development of networks for wireless access has enabled this technology to establish itself as an important tool for telecommunications. Whether complementing conventional wired networks or providing mobility to users and devices, the current corporate wireless LANs have high availability features, management, performance and safety.

The quick installation and costs ever lower wireless networks become highly attractive to several segments.

However, the wide availability and variety of solutions, and the rapid evolution of standards and codes, require great care in specifying an appropriate solution for each case.

Factors like the size and complexity of the network, the electromagnetic environment at the installation site requirements, access control, information security and criticality, and also need network availability, it is imperative, a careful design and a correct choice of type and quantity equipment to be employed.

Active Network Equipment:

The network equipment assets provide the necessary infrastructure to support the applications of data communication in an organization.

More than simply providing connectivity to network devices, switches and routers currently constitute the nerve center of information technology systems. It is the function of such equipment, ensure performance, security, reliability, availability and flexibility required by modern network applications.

A wide variety of suppliers and equipment solutions network assets requires a perfect planning of the organization’s needs, so that the investment is aligned with business strategy.

Structured Cabling and Optical Networks:

The structured cabling system includes the planning of all the telecommunications needs of an organization by using a single infrastructure.

The conventional networks (a unique structure for each application) are rigid and costly, they require different firms or teams to carry out installations and maintenance. This is an important factor for the contractor, who can unify the company that handles all the wiring, or hire someone to take care of maintenance because there is only one structure.

Using the same distribution components regardless of the type of telecommunications service or device to be used to guarantee, from a technical standpoint, the reliability, flexibility, expandability, performance and longevity of the building or campus facilities, the financial point of view : The benefits are investment protection, reduced maintenance costs and expansion, and consequently reducing the total cost of ownership (TCO).

Infrastructure of Virtualization:

Virtualization allows a hardware to do the work of many others, by sharing resources such single physical machine between several different virtual environments.

Dedicated Servers and virtual desktops let you host multiple operating systems and applications locally or remotely, freeing you from physical and geographical limitations. Also generates, saving resources such as electricity and reduction in investments, because the efficient use of hardware will achieve better results in the availability of services, better desktop management, increased security and improved processes for disaster recovery. All this when you build a virtual infrastructure.

Here are the Top 5 reasons to adopt virtualization:

1. Server Consolidation and Infrastructure Optimization: Virtualization makes it possible to achieve significantly higher levels of resource utilization through shared infrastructure and the breakdown of the model legacy “one application for each server”.

2. Cost reduction with physical infrastructure: With virtualization, you can reduce the number of servers and other hardware-related IT in the Data Center. This leads to reductions in physical infrastructure, power and cooling requirements, resulting in significantly lower IT costs.

3. Operational Flexibility and improved Responsiveness: Virtualization offers a new way of managing IT infrastructure and can help IT administrators spend less time on repetitive tasks such as provisioning, configuration, monitoring and maintenance.

4. Increased application availability and improved business continuity: Eliminate planned downtime and recover quickly from unplanned outages with the ability to perform backups in a safe manner and migrate entire virtual environments without interfering with ongoing services.

5. Improved Desktop Management and Security: Deploy and monitor secure desktop environments, where end users can access locally or remotely, with or without network connection, on almost any desktop machine, laptop or tablet PC.
