Cloud Databases : A shift towards new paradigm.
ABSTRACT
.In this paper, we analyze the design choices that allowed modern scalable data management systems to achieve orders of magnitude higher levels of scalability compared to traditional databases. The challenge of building consistent, available, and scalable data management systems capable of serving petabytes of data for millions of users has confronted the data management research community as well as large internet enterprises. Current proposed solutions to scalable data management, driven primarily by prevalent application requirements, limit consistent access to only the granularity of single objects, rows, or keys, thereby trading off consistency for high scalability

Cash-strapped organizations look for alternatives which can reduce their capital investments involved in purchasing and maintaining IT hardware and software so that they can get maximum benefits of IT. Cloud computing (CC) becomes a natural and ideal choice for such organizations and customers. Cloud computing takes benefit of many technologies such as server consolidation, huge and faster storage, grid computing, virtualization, N-tier architecture and robust networks. It delivers highly scalable and expensive infrastructure with minimal set up and negligible maintenance cost. It provides IT-related services such as Software-as-a-Service, Development Platforms-as-a-Service and Infrastructure-asa-Service over the network on-demand anytime from anywhere on the basis of “pay-as-you-go" model. It is a fast growing concept changing the IT related perceptions of its users. Elasticity, scalability, high availability, priceper-usage and multi-tenancy are the main features of Cloud computing. It reduces the cost of using expensive resources at the provider’s end due to economies of scale. Quick provisioning and immediate deployment of latest applications at lesser cost are the benefits which force people to adopt Cloud computing. Cloud computing has brought a paradigm shift not in the technology landscape, but also in the database landscape. With more usage of Cloud computing,
The focus of cloud computing is providing with scalable and a cheap on-demand computing infrastructure with a good quality of service levels. The process of the cloud computing involves a set of network enabled services that can be accessed in a simple and general way. Cloud computing provides with a unique value proposition for any organization to outsource their information and communication technology infrastructure. Moreover, the concept itself provides with a value proposition for an organization as using the cloud saves on cost, resources, and staff, and business opportunities for the organization (Katzan). An extensive connectivity of
Cloud computing is defined by Cearly and Phifer in their case study titled “Case Studies in Cloud Computing” as “a style of computing in which scalable and elastic IT-related capabilities are provided ‘ as a service’ to customers using Internet technologies”. Cloud computing services had been provided by major vendors such as Google, Amazon, Microsoft, IBM, Hewlett-Packard, and others for business computing until recently when Apple Corporation announced iCloud for consumers. Therefore, cloud computing is now available for businesses as well as consumers. Read the case study titled, “ Ericsson”, located here, about Ericsson cloud computing.
The world has recently adopted a new approach to computing – cloud computing. It is a particularly new model of computing, where databases are stored and operated somewhere in a cloud. Mell and Grance (2011) define cloud computing as “a model for enabling ubiquitous, 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” (p. 2). In other words, the cloud is considered a remote computing data center that one can access either on the subscription or “pay-as-you-go” basis. Thus, cloud computing relates to the hardware, applications, and system software that provide
The main purpose of the study is to provide the information of cloud computing. Here the definitions of cloud computing is described including the briefing about what cloud computing and why it is used. Moreover, it includes brief overview of deployment models and service models of cloud computing. It will help to get a better and clear idea about how organizations can access cloud. It includes advantages and drawbacks of using cloud computing in organizations.
Cloud computing, has opened a new potentiality for technology and computer science of the future. In recent years, IT industry has completely evolved from its demand for the purchase of software, hardware and information systems. Information architecture is provided these days as a service, which is divided into three main segments: "Applications", "Platform" and "Infrastructure”. The main goal of cloud computing is to provide users with a more flexible and scalable computing applications, data storage and the platform in a transparent manner. By using cloud-computing platform, organizations can easily capture and deploy the necessary services and operations with the help of the Internet, but without the need to configure
Over the past several years, cloud computing has been getting attention as a new computing model for providing flexible and on-demand infrastructures, platforms, and software as services. Cloud computing is a technology through exchange of information and software management. Cloud computing allows users to use computer technology without the installation in their computers. It allows users to access their files or data from any computer having an internet connection. Cloud computing provides more efficient computing by centralizing data storage, processing and bandwidth. This technology emphases on virtualization of the host server or the controlling computer. The server acts as a communication network through which information could be shared. The information can be stored, retrieved and shared as and when required through a widespread global platform.
Cloud computing is the new buzz in the recent days and cloud computing allows users to share files and applications over the internet. In the following pages we will discuss about the cloud computing its pros and cons, the security risk and how to overcome and use its resources for the best advantage of organizations. It is attracting much of the attention now-a-days which can be seen by observing the big names of the IT industry like IBM, Microsoft and Google investing millions of dollars into research on cloud computing.
Cloud computing is the growing method of computing adopted by many organizations nowadays around the world. The word ‘cloud’ refers to the network, the servers providing the cloud services can be located anywhere in the world (Garg & Buyya, 2012). The services are provided through internet and made available to the end users. Several definitions are given for the cloud computing in the literature. According to (Mell & Grance, 2011), “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.” Different advantages of having cloud computing includes, services are available on demand, the users have to pay only as per the use and the services are accessible from anywhere as it is available over network. There are different service models and deployment models available for cloud computing.
Cloud computing is a mixture of distributed system, utility computing and grid computing. In cloud computing, use combination of all these three in virtualized manner. Cloud computing converts desktop computing into service based computing using server cluster and huge databases at data center. Cloud computing gives innovative facility like on demand, pay per use, dynamically scalable and efficient provisioning of resources. Cloud computing the new developed technology of distributed computing systems changed the phase of entire business over internet and set a new trend.
Cloud computing is currently being used by a large number of organizations. Many consider it a major development of the decade in computing. In this article I define cloud computing, various services available on the cloud infrastructure, then discuss the technological trends which have led to its emergence, its advantages and disadvantages, and the applications which are appropriate to outsource to a cloud computing service.
This paper will outline and describe three vendors that provide the Hadoop NoSQL database program to enterprises. Each of these companies see themselves as uniquely different, thus positioning themselves within a market place that has begun to become highly competitive in the “Big Data” age. I will provide an outline of the talking points that will be discussed for each company, starting with a brief description of the Hadoop NoSQL open-source database program, then I will discuss each company on the evaluation categories, and conclude with options for whether to move forward with either of these vendors. After the conclusion the reader will have the information on these vendors and the confidence to be able to decide on which choice would be best for the business.
In Nowadays, there are two major of database management systems which are used to deal with data, the first one called Relational Database Management System (RDBMS) which is the traditional relational databases, it deals with structured data and have been popular since decades since 1970, while the second one called Not only Structure Query Language databases (NoSQL), they are dealing with semi-structured and unstructured data; the NoSQL types are gaining their popularity with the development of the internet and the social media since April 2009. NoSQL are intending to override the cons of RDBMs, such as fixed
In this report I am going to discuss about No SQL databases and the criterion that are to be taken into consideration when choosing a database that best supports your product. NoSQL databases enclose a variety of database technologies and was developed in response to rise in volume of data unlike relational databases which were built to handle structured data [1].
Information technology continues to revolutionize the interactions of mankind in various ways, through social media, business, education and other channels. The internet has made it possible to transmit large data across many networks. These networks have made it possible to store, access and query billion of data from large databases. Innovation has given rise to special language used to manage and access all sorts of information within various databases know as SQL. Recently a new generation of SQL known as NoSQL has been developed. NoSQL store related data in JSON-like, name-value documents and can store data without specifying a schema. One such type of NoSQL database that has been developed is the IBM Informix
Define the structure of a database: data types and restraint that the data have to satisfy.
