virtualization and virtual service delivery through IT “cloud of ” is the main topic of discussion in IT circles today. It’s actually hard to avoid the discussion because on some levels, the concept of virtualization is so appealing. The idea of ​​delivering IT services without having to build, manage and maintain means that smaller companies could take advantage of low cost technologies.

inherent limit of decentralized computing, however, is scalability. It turns out that there are limits to the number of servers a company can add, without incurring significant costs for data center space capabilities, disaster recovery, maintenance, licensing and support. business computing is a critical component of business models and more organizations, but maintaining the decentralized computer seems to be both practical and prudent.

computer was not centralized because small businesses have adopted a decentralized approach to computing. In fact, the opposite happened. giants virtualization today quietly improve their products, targeting large enterprises and their participation in the primary market . Today, they have increased processing power and memory capacity of centralized servers, centralized services designed to attract companies of all sizes and products that meet the “server sprawl “that SMEs (Small and Medium Enterprises) are faced daily. By making virtualization technology and affordable for small and medium enterprises, suppliers of virtualized IT infrastructure can help SMEs to provide better IT services at a cost lower.

What are the main advantages of cloud computing?

By far, the benefit of virtualization is a significant reduction in the cost of the infrastructure of information technology for a particular computing environment. Al divorce server software from the server hardware, and just as between the desktop client, desktop computer, companies can spend less on their IT infrastructure. That means fewer servers at the site, “ fine “on customers’ desktops, virtualized data storage, better management of licenses and even virtual networks.

companies spend less because they add new hardware every time you want add a new server. At the same time, virtualization means that individual users can have the operating system environments that need (or prefer) without the costs associated with buying a complete desktop unit and individual copies of licensing software.

companies spend less on disaster recovery infrastructure and business continuity. On the other hand, are based on a common infrastructure partitions (and instantly reconfigurable) to suit your needs. Add more storage space does not mean adding more disks, and IT infrastructure resources do not always need to be dedicated to a particular business function.

This is all very well, but virtualization works

What are the main disadvantages of virtualized IT infrastructure?

The impact of physical hardware failure can not be underestimated. Hardware can and can not do, and if not, can cripple servers and processes running on it. If you are operating your own virtual IT infrastructure, which may or may not be able to address the problem immediately. If virtual IT services contract through a provider, you need to know what their capacity to respond physical fault. Ask about service level guarantees and develop a plan to support their most critical business processes and data.

In addition to the effects of physical failure, the solution of problems within the cloud can be complicated. With part of its infrastructure beyond their control, have to rely on the skills and experience of their virtual infrastructure provider of the information.

servers and freedom to create other virtual machines on a basis of need can be tempting because it can create almost instantly. Without careful guidance about what justifies a new server, you could end up with a lot of under-utilized (or simply unnecessary) machines virtual. The justification process for creating a new virtual server should be similar to the process of your organization to justify the purchase of server hardware, if only because the creation of virtual machines does not absorb the resources.

is privacy possible in cloud computing?

One of the biggest questions about the virtual infrastructure (that is, by definition, shared) is whether or not the controls in place to achieve the level of data security and privacy users may be necessary, either as a matter of law or. matter of best business practices are your data – create and store in some other resource -? safe from foreigners who are not access to it Is the virtual IT infrastructure robust enough to prevent users from their own organization inadvertently or deliberately accessing restricted data In a virtual IT infrastructure, the person or organization that generates the data gives up some measure of control over it. The organizations must rely on the infrastructure provider to support, maintain and strengthen data security at all times.
When an organization manages and maintains its own data and IT infrastructure, the ownership of data and data management responsibilities are clear. When data is created and maintained in a cloud, these seemingly simple questions have no easy answers.

Can a government authority to access data through the IT infrastructure provider How are security breaches? Who is responsible for damages resulting when confidential data have been stolen or misappropriated from the cloud? What about the orphaned data? When the ownership of data is discussed, how the IT infrastructure provider virtual address? provider can deny access to the organization of their own data and, if so, under what circumstances? If certain types of data are excluded from being created or stored in the cloud? What happens to data if a virtual IT provider closes or is acquired by another company?

Wed laws relating to information, information security and privacy of information are constantly evolving. Often, significant regulations do not develop until a major incident exposes the weaknesses in current laws and practices . Too often, consumers fail to respond to these important questions on their own, without any significant legal protections or above. In the absence of meaningful regulation, the industry guidelines and best practices often enough. This approach can be powerful among suppliers and consumers responsible, but lacks the applicability of the law.

A lack of specific legal provisions for handling sensitive data in the virtualized environment, the best backup option is a contractual agreement or set of agreements between the parties that specifies the rights and responsibilities of creators virtual IT provider and data, and the penalties that can be followed in the event of a breach of contract.
