Private Cloud Using Open Source Operating System Ubuntu 10.04 Server

Cloud Computing is a fairly new term used to identify a type of computer connectivity, IT services and on-demand delivery offered via the web. The way that it works is, Cloud Computing offers an easy approach to accessing servers, storage, databases and a wide set of request over the Internet. Cloud Computing also allows cloud-based service providers to own and sustain the network-connected equipment necessary for these application services. This is all done while permitting a business to facilitate and use the services that are deemed essential via a web application (Amazon, 2016).

The issue of cloud computing refers to either the applications that are delivered in the form of services on the internet or the systems software and hardware in the data centres that are meant for the provision of those services (Dinh, et al. 2013). As outlined by NIST, there are usually four main cloud delivery models. The cloud models are

The world is turning to cloud computing to manage data. Businesses are at the forefront of this new trend with companies such as Google, Amazon, Microsoft, and others leading the way by providing these services. What exactly is cloud computing? According to Turban & Volonino (2011), cloud computing is Internet- based computing in which shared resources (such as hard drives for storage) and software apps are provided to computers and other devices on- demand (p. 48).

Cloud Computing has been a buzz world in the past few years. The use of this technology increased considerably when we made huge progress in this domain, reducing the cost for everyone. Today, Cloud Computing is widely used all across the world by a lot of companies such as Microsoft, Facebook, Amazon, etc…

The National Institute of Standards and Technology defines cloud computing as a model that allows convenient, on-demand network access to a pool of configurable computing resources. These resources may consist of storage, networks, servers, applications, services and so forth that can be quickly provisioned and put into service while requiring a minimum of management effort or interaction by the service provider (Mell & Grance, 2011).

Cloud computing has been defined by NIST as a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or cloud provider interaction. Cloud computing can be considered a new computing paradigm insofar as it allows the utilization of a computing infrastructure at one or more levels of abstraction, as an on-demand service made available over the Internet or other computer network.

Cloud computing is a popular and widely accepted paradigm built concepts such as on-demand computing resources, elastic scaling, elimination of up-front capital and operational expenses, and establishing a pay-as-you-use business model for computing and information technology services. And the adoption of virtualization, service oriented architectures, and utility computing there has been a significant development in the creation of cloud

Cloud Computing provide enterprises and users with varieties of capabilities for store and process data in the data centers of third-party. It depends on resources sharing to carry out accordance and economies of scale, like a utility over a network. The basic of Cloud Computing is the extended concept of sharing services and aggregate infrastructure. It is the product of evolution and using current exponents and technologies.

Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.

Cloud computing is an advanced IT model to host and share both software and hardware resources over the Internet. It allows organisations to use a pool of IT resources

"Cloud Computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications and services) that can be rapidly provisioned and released

Cloud computing is an advanced computing technology based on the Internet environment to share the computing resources. Cloud computing refers to the services and applications delivered via Internet and also refers to hardware and software in the datacenters that provide those services. Cloud computing model has five characters, three service models, and three deployment models [1].

The overall concept of cloud computing is one which is based on a new architectural model of computer resources which means the data is stored remotely, but is provided to users as if it was stored locally. This new concept has been described as being "a style of computing where massively scalable IT-enabled capabilities are delivered 'as a service' to external customers using internet technologies" ("Will IT of the Future Have Its Feet Firmly Planted in the "Cloud"?," 2008), in a dramatic shift from traditional computing methods. Cloud computing is also able to provide services to the end user seamlessly, to serve applications from a central location, regardless of the user’s location. There are numerous services such as

With a significant development of the era of internet information, numerous data from vary field like science, engineer and business need to be handled quickly and accurately, which means the demand of computing power is far more than the ability of current technology. In order to enhance the computing system and save cost, ‘Cloud computing’ was emerged. People use cloud computing commonly in storage, which allow consumers use internet to share or store resources and information. The concept of this technology was proposed initially by John McCarthy in 1960s, while he predicted, computing will become a part of infrastructure instruction like gas, water and electricity everyone can get and use it easily and cheaply. The
