Cloud computing involves a lot of concepts and technologies. Companies and corporations such as Amazon, Google and Microsoft are providing services following the logic of computational infrastructure cloud computing, with Amazon the pioneer in providing and marketing infrastructure of this kind.
The academic community has also shown interest in cloud computing, and some work has been directed to improvements in aspects of performance, security, usability, implementation and reliability of the system as a whole (Armbrust et al. 2009). Other work has developed new techniques to make adequate infrastructure to each context of cloud computing environments, among which we highlight the project Eucalyptus (Liu et al. 2007), developed by the University of California. The following are some technology, such a model of programming, infrastructure and platforms for cloud computing.
MapReduce/Hadoop
The MapReduce (Dean and Ghemawat 2004) is a model of programming aimed at processing large volumes of data, where the user specifies your application through the sequence of MapReduce operations. The tasks of parallelism, fault tolerance, data distribution and load balancing are left to the MapReduce system, simplifying the development process. From the standpoint of distributed systems, MapReduce offers the transparency of replication, distribution and synchronization.
Each operation of the MapReduce model consists of two functions. The first call mapping function receives a portion of the input file and according to the specification of the user issues a set of intermediate key-value pairs. The second function, called reduction, given a set of values associated with each key, called block. The processing defined by the user and perform...

Cloud computing is 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 service provider interaction. This cloud model promotes availability and is composed of five essential characteristics, three service models, and four deployment models.
To understand how cloud computing can be of value to an organization, it is important to us that we understand the cloud and its components. There are three different types of cloud computing services referred to as Infrastructure as a Service (IaaS), Software as a Service (SaaS) and Platform as a Service (PaaS). IaaS delivers cloud computing infrastructure servers, storage, network and operating systems as an on-demand service. SaaS is about software deploying over the Internet. PaaS allows a creation of web applications without the complexity of buying and maintaining the software and infrastructure. In this paper, I will suggest that Innovartus Technology Inc should use IaaS as a replacement for PaaS because IaaS is a rapidly developing field with resources such as better services, cost variability, utility pricing model and dynamic scaling.
Cloud computing can be defined as: “a variety of computing concepts that involve a large number of computers connected through a real-time communication network such as the Internet.” Our understanding of cloud computing is distributed computing over a network with the ability to run a program or application on many connected computers at the same time.
There is a lot of buzz about “the Cloud” and what it can and cannot do for IT departments. A wide range of products and services are lumped into the phrase “Cloud computing.” While the strict definition of a cloud speaks mainly to a collection of easily deployed virtual servers, it also encompasses vendors of outsourced exchange servers, preconfigured CRM applications, web-enabled word processing applications, and online backup services (Gohring, 2013).
As its core essences cloud computing is nothing but a specialized form of grid computing and distributing computing’s which various in terms of infrastructure , deployment, service and Geographic’s dispersion (Veeramachanenin, Sepetember 2015) the cloud enhance scalability, collaboration, availability , ability to adapt to fluctuation according to demand accelerate development work and provide optional for cost reduction and through efficient and optimized computing. (BH kawljeet, June 2015) cloud computing (CC) recently become as a new paradigm for the delivery and hosting of services our the internet. There are mainly three service delivery model Software as Service (SaaS) required software, operating system and network is provided or we can say in SaaS the customer can access the hosted software instead of installing it in local computer and the user can access these software through local computer internet browser (e.g web enabled E-mail ) the user only pay and the cloud service provider is responsible for management or control of mobile cloud infrastructure some of the company which provide such service are Google, Microsoft , Salesforce ,Facebook, etc…..Infrastructure as Service(IaaS)the cloud provider only provide some hardware resources such as network and virtualization is
Hadoop is a free, java based programming framework that usually supports processing of large data sets that are in diverse computing environment. Hadoop is a cluster computation framework. Apache Hadoop is a programming framework that provides support to data intensive distributed applications with a free license. The program was inspired by Google file and Google’s MapReduce system (Eadline, 2013). According to Eadline (2013), the Hadoop technology was designed to solve various problems such as to provide a fast and reliable analysis for both complex and clustered data. Consequently, different organizational enterprises deployed Hadoop with the existing IT systems, thereby, allowing them to combine old and new data in a strong framework. The major industrial players who used Hadoop technology include IBM, Yahoo, and Google (Lavalle, Lesser, Shockley, Hopkins & Kruschwitz, 2011).
The word cloud is used as a metaphor for the Internet, based on the standardized use of a cloud-like shape to denote a network. A cloud is a combination of hardware, networks, storage, services, and interfaces that helps in delivering computing as a service. Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort or service provider interaction. In addition, the platform provides on demand services to the users for accessing that are always on anywhere, anytime and any place. Cloud computing platform provides the scalability, availability and utility computing for services on Internet.
Enterprises and individual users are outsourcing their services on the web, instead of maintaining the resources of their own. Outsourcing of technical resources enables the organization to concentrate on business need instead of technical aspect, which is looked after by the expert of the IT area. To facilitate such users, a web based paradigm known as cloud computing has emerged and offering the services on utility model [p3]. The major goal of Cloud computing is to reduce the operating cost, increase throughput, increase the reliability and availability [p10].

Cloud computing is being heralded as the onrushing future of computing. In fact, in many ways, cloud computing is already here, and has been for some time. The most obvious example of cloud computing is Google Mail. Cloud computing, simply defined, is the implementation of computing services using shared hardware, shared software and in many cases even shared information. Google Mail, for example, makes e-mail services available using a widespread, highly redundant network of systems that remove that same functionality and data from the user’s computer, putting it “in the cloud” where it can be plucked back out as needed – from any capable device such as a smart phone, computer or internet kiosk.
Clouding computing is very popular services which people talk and look forward to use now a day with a lot of research are ongoing for the cloud is worthy to be invested in. Very popular service like Gmail, Google drive, Facebook, Dropbox, etc… which people now a day used are obvious cloud technology. Moreover, most of the enterprise, SME and governments are looking forward to implement cloud base solutions to settle technology challenges, reducing costs, targeting new levels of efficiency and trying to create innovative business models.
The term "the cloud" is essentially a metaphor for the Internet] Marketers have further popularized the phrase "in the cloud" to refer to software, platforms and infrastructure that are sold "as a service", i.e. remotely through the Internet. Typically, the seller has actual energy-consuming servers which host products and services from a remote location, so end-users don't have to; they can simply log on to the network without installing anything. The major models of cloud computing service are known as software as a service, platform as a service, and infrastructure as a service. These cloud services may be offered in a public, private or hybrid network. Google, Amazon, IBM, Oracle Cloud, Salesforce, Zoho and Microsoft Azure are some well-known cloud vendors.
One might ask how does cloud computing work? Cloud computing architecture refers to the components that work together to form cloud computing. The architecture behind cloud computing involves two different parts, the front end and the back end. Each part connects through the internet and works together. The front end structure is also referred to as the clients. This is the part or side of the server that the user interacts with and sees. For the user to connect and interact with this end, they need to have access to a computer with internet. An example of the front end structure being used is a user logging on the internet to check their email. Again, millions of people check their email every day and do not realize it is part of cloud computing. The other part of cloud computing architecture is called the back end structure. This part is responsible for the service that make the cloud work. It comprises of huge data storage, virtual machines, security mechanism, services, deployment models, servers, etc. () The back end service is made up of Software as a Service (SaaS), Platf...
Cloud computing is the progression of other computing technologies such as paral-lel computing, distributed computing, and grid computing. Its main principle is to disseminate the computing grind stones to distributed computers. Majority of us still use the PC’s and laptops to cache the data and files, sharing of data and files, and to send emails. If our pc’s diverse...
In cloud computing, the word cloud is used as a metaphor for “the internet”. So the cloud computing means “a type of internet-based computing”, where different services such as servers, storage and applications are delivered to an organization’s computers and devices through the internet.
