Recognised by cloud economists as the best value private cloud.
September 01, In the last few years, Information Technology IT has embarked on a new paradigm — cloud computing. Although cloud computing is only a different way to deliver computer resources, rather than a new technology, it has sparked a revolution in the way organizations provide information and service.
Originally IT was dominated by mainframe computing. This sturdy configuration eventually gave way to the client-server model. Contemporary IT is increasingly a function of mobile technology, pervasive or ubiquitous computing, and of course, cloud computing.
But this revolution, like every revolution, contains components of the past from which it evolved. Thus, to put cloud computing in the proper context, keep in mind that in the DNA of cloud computing is essentially the creation of its predecessor systems.
In many ways, this momentous change is a matter of "back to the future" rather than the definitive end of the past. In the brave new world of cloud computing, there is room for innovative collaboration of cloud technology and for the proven utility of predecessor systems, such as the powerful mainframe.
This veritable change in how we compute provides immense opportunities for IT personnel to take the reins of change and use them to their individual and institutional advantage.
What is cloud computing? Cloud computing is a comprehensive solution that delivers IT as a service. It is an Internet-based computing solution where shared resources are provided like electricity distributed on the electrical grid.
Computers in the cloud are configured to work together and the various applications use the collective computing power as if they are running on a single system. The flexibility of cloud computing is a function of the allocation of resources on demand.
Before cloud computing, websites and server-based applications were executed on a specific system. With the advent of cloud computing, resources are used as an aggregated virtual computer. This amalgamated configuration provides an environment where applications execute independently without regard for any particular configuration.
Why the rush to the cloud? There are valid and significant business and IT reasons for the cloud computing paradigm shift. The fundamentals of outsourcing as a solution apply.
Cloud computing can reduce both capital expense CapEx and operating expense OpEx costs because resources are only acquired when needed and are only paid for when used.
Refined usage of personnel: Using cloud computing frees valuable personnel allowing them to focus on delivering value rather than maintaining hardware and software. Cloud computing allows for immediate scaling, either up or down, at any time without long-term commitment.
Cloud computing building blocks The cloud computing model is comprised of a front end and a back end. These two elements are connected through a network, in most cases the Internet.
The front end is the vehicle by which the user interacts with the system; the back end is the cloud itself. The front end is composed of a client computer, or the computer network of an enterprise, and the applications used to access the cloud. The back end provides the applications, computers, servers, and data storage that creates the cloud of services.
Computing as a commodity The cloud concept is built on layers, each providing a distinct level of functionality. The commodity that cloud computing sells is computing power at a lower cost and expense to the user.
Cloud computing is poised to become the next mega-utility service. The virtual machine monitor VMM provides the means for simultaneous use of cloud facilities see Figure 1. VMM is a program on a host system that lets one computer support multiple, identical execution environments.
In reality, every user is being served by the same machine. A virtual machine is one operating system OS that is being managed by an underlying control program allowing it to appear to be multiple operating systems. In cloud computing, VMM allows users to monitor and thus manage aspects of the process such as data access, data storage, encryption, addressing, topology, and workload movement.

The investment objective of the Fund is to seek investment results that correspond generally to the price and yield, before the Fund's fees and expenses, of an equity index called the ISE Cloud Computing Index.
The index is a modified market capitalization weighted index designed to track the performance of companies actively involved in the cloud computing industry. Seth Noble is founder and president of Data Expedition.. Moving terabytes or even petabytes of data to the cloud is a daunting task.
But it is important to look beyond the number of bytes.
