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 is the result of a decade research in the field of distributing computing , utility computing, virtualization , grid computing and more recently software, network services and web technology which is changeable evolution on demanding technology and services also as looking to the rapid growth of cloud computing which have changed the global computing infrastructure as well as the concept of computing resources toward cloud infrastructure. The important and interest of cloud computing increasing day by day and this technology receives more and more attention in the world (Jain, 2014) the mostly widely used definition of cloud computing is introduced by NIST “as a model for enabling a convenient on demand network access
Cloud computing is defined by experts as a type of computing that relies on sharing computing resources rather than having local servers or personal devices to handle applications. The meaning behind the word cloud is that it is a metaphor for the entire online web and its data as well. A cloud service differs from traditional hosting in three different ways. These three differences are that cloud computing is elastic, it is sold on demand, and the service is managed by the provider of the cloud. The easiest way to explain what cloud computing does is that it stores and gives access to different data and programs over the internet rather than just your computer’s hard drive. For it to be actually considered cloud computing it must include data or programs over the internet. Cloud computing can be done anytime, anywhere with an online connection.
Big Data is a term used to refer to extremely large and complex data sets that have grown beyond the ability to manage and analyse them with traditional data processing tools. However, Big Data contains a lot of valuable information which if extracted successfully, it will help a lot for business, scientific research, to predict the upcoming epidemic and even determining traffic conditions in real time. Therefore, these data must be collected, organized, storage, search, sharing in a different way than usual. In this article, invite you and learn about Big Data, methods people use to exploit it and how it helps our life.
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.
You can define distributed computing many different ways. Various vendors have created and marketed distributed computing systems for years, and have developed numerous initiatives and architectures to permit distributed processing of data and objects across a network of connected systems. They have developed a virtual environment where you can harness idle CPU cycles and storage space of tens, hundreds, or thousands of networked systems to work together on a particularly processing-intensive problem. The growth of such processing models has been limited, however, due to a lack of compelling applications and by bandwidth bottlenecks, combined with significant security, management, and standardization challenges. A number of new vendors have appeared to take advantage of the promising market; including Intel, Microsoft, Sun, and Compaq that have validated the importance of the concept.1 Also, an innovative worldwide distributed computing project whose goal is to find intelligent life in the universe--SETI@Home--has captured the imaginations, and desktop processing cycles of millions of users and desktops.
1. Introduction In the year 2016, the size of the market for big data analytics in India was two billion USD and it is expected to grow approximately by eight times to reach around sixteen billion USD by the year 2025, as per the National Association of Software and Services Companies (NASSCOM)1. India currently ranks among the top ten big data analytics market of the world1. According to Mr. K. S. Viswanathan, Vice President, NASSCOM, the big data sector in India is expected to grow at a Compounded Annual Growth Rate (CAGR) of twenty six percent over the next five years and it will have a thirty two percent share in the global market2.
It presents a novel approach by providing a parallel two-way integration with Hadoop. All writes from the real-time tier make it into Hadoop and output of analytics inside Hadoop can emerge in the in-memory “operational” tier and distributed across data centres. The idea is to leverage distributed memory across a large farm of commodity servers to offer a very low latency SQL queries and transactional updates. 6) Strategic Direction Pivotal’s road map has given a strategic direction to its Hadoop solution and has made it significantly more competitive; its innovations focuses on improving the HAWQ SQL engine and integration with other Pivotal
Google File Systems (GFS) is developed by Google to meet the rapidly growing demand of Google’s data processing needs. On the other hand, Hadoop Distributed File Systems (HDFS) developed by Yahoo and updated by Apache is an open source framework for the usage of different clients with different needs. Though Google File Systems (GFS) and Hadoop Distributed File Systems (GFS) are the distributed file systems developed by different vendors, they have been designed to meet the following goals:
The cloud computing is the practice that enables access to the shared pool of configurable computing resources which can be dynamically provisioned. It refers to both the applications delivered as service as well as hardware and system software in the data centres that provide those services. The attractive features of cloud computing such as on-demand access, high scalability, reliability, cost savings, low maintenance and energy efficiency bring benefits to both cloud service consumers and providers.
The fourth characteristic of cloud computing is broad network access. The applications that are available through cloud services are accessible through a variety of devices and locations, allowing users to access applications through various types of storage not limited to the local hard drive. Furthermore, with cloud computing, users can access applicat...
Cloud computing is the transfer of computing data or information into Internet. Cloud computing services allows individuals and businesses to
The notion of Cloud computing has not only reshaped the field of distributed systems but also undamentally changed how businesses utilize computing today. While Cloud computing provides many advanced features, it still has some shortcomings such as the relatively high operating cost
Cloud computing are functions that are provided as a service. Cloud computing is a form where Input and Output(I/O) operations take place in terminal device such as workstations, smartphones, tablets. However, information analysis, processing, storage, management and distribution of operations takes place in the third space called the cloud. Software and data are typically stored on the server in the cloud. However, the users only have their device as temporary storage for the duration of use. Most users can use the cloud service over the internet using the browser such as Internet Explorer, Chrome, Firefox, and Safari without understanding about technology infrastructure. Cloud service is an on-demand service used to satisfy the user.
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.
Businesses are trending toward the use of cloud computing to assist them with many aspects of their operations. Cloud computing consists of a pay-per use or subscription service to the internet (real time), thus extending the use of a business’s information technology’s capabilities. Cloud computing technology allows for business to increase their information technology capacity and capabilities without ever investing in new infrastructure, training new personnel, or licensing ...
