Many cloud computing services are Cloud computing has become interesting area both in implementing on distributed web environment and academia and industry. Semantic Web has been an provides virtualized resources, which focuses on some important research area in academic and industrial aspects like the semantic ambiguity, distributed researchers. Many applications will need to work with semantic reasoning, distributed semantic models large amounts of data, one particular application would construction, distributed metadata storage, parallel certainly not exist without the capability of accessing and semantic computing, etc. It also introduces many real processing arbitrary amounts of metadata: search world applications like semantic analysis in science engines that locate the data and services that other computing, cloud resource discovery, accurate applications need. To solve this problem, semantic web advertise recommendation, and web context services used with cloud computing. In this paper we understanding in commercial services. present the use of well established semantic technologies The Semantic Web is gaining immense in Cloud computing. The purpose of this report is to give popularity. Tim Berners Lee’s vision of the Semantic an overview of semantic web services and semantic web Web or Web 3.0 is to transform the World Wide Web technologies in cloud computing. into an intelligent web system of structured, linked data Keyword: Semantic Web Services, Semantic Web which can be queried and inferred as a whole by the Technologies, Cloud Computing, Semantic Web computers themselves. Interoperable applications hosted on the web as service for customers and these I. Introduction web services are designed to be automatically IJSERdiscovered by software agents and exchange data Now a day, Internet provides many more services such amongst themselves. In internet, the cloud computing as instant message, sharing videos, web search, e- platform is another business model, where hardware, commerce platforms, online video conference, and software, applications and tools all will be use as image processing, and various other types of third- public. The main purpose of this paper is to provide a party services on the Web. This require huge amount of research survey on semantic web technologies and memory space on web database to improve online semantic web services. performance and the demand for real-time applications The paper is organized as follows section 2 and high-speed data processing. Because of this, many contains brief introduction for cloud computing to organizations causes a problem to construct large provide the base of this concept. Section 3 describes datacenter to satisfy their demand. As a solution to Semantic Web with their technologies and services. these problems, cloud computing technology used by Section 4 concludes this study. various companies. The companies which provide web services no longer need large capital outlays in II Cloud computing hardware and software to deploy their services. Those companies can just buy these “hardware” and The term "cloud" is group of network in computer. The “software” as cloud computing services on the Web. word "cloud" often refers to the Internet and more To build large datacenter required more money to build precisely to some datacenter full of servers that is their services on cloud. Cloud computing provides on- connected to the Internet. In internet, Cloud computing demand self-service, , measured service, resource is a kind of Internet-based computing, where shared pooling, broad network access and rapid elasticity[1]. resources, information and data are provided to Developers can easily implement their creative ideas computers on-demand. At the time Google started in 1998, its business increased so rapidly that the internet IJSER © 2016 http://www.ijser.org International Journal of Scientific & Engineering Research, Volume 7, Issue 2, February-2016 ISSN 2229-5518 379 technologies are not enough to process the huge new proposed cloud computing model for large scale amount of data in acceptable manner. To solve this graph processing. It can avoid multiple iterations in problem, they develop its own file system Google File MapReduce framework and give stable and scalable System (GFS) [3], and built its parallel computing performance. Pig-latin [7], a SQL-like and data flow environment MapReduce [4] based on GFS. These language can be implemented on Pig [8] to perform technologies which are later called “cloud computing” database-like functionality. turned out to be high efficient, stable and reliable. To access web service, firstly user has to login According to "The NIST Definition of Cloud to the websites who provides cloud service then they Computing" [2], cloud computing is “the delivery of can select any web service that they needed. Users can computing as a service rather than a product, whereby set up their real-time applications on cloud by using shared resources, software, and information are different virtual resources like hard disks, CPU provided to computers and other devices as a utility processors and memories and they can run their web (like the electricity grid) over a network (typically the services application on the platforms of cloud service. Internet)”. In cloud computing everything can be If users want to develop any application then, they can provided as service, including infrastructure, hardware just adopt the existing software services in the cloud. platform, software, etc. The cloud computing model III Semantic Web can be mainly classified into three layers [2]: Cloud Software as a Service (SaaS), Cloud Platform as a "Semantic Web" was coined by Tim Berners-Lee ( Service (PaaS), and Cloud Infrastructure as a Service inventor of the "W3C"). The Semantic web is a (IaaS). In SaaS, the capability provided to the polymorphism of similar data on web. The Semantic consumer is to use the provider’s applications running Web is an extension of the Web through standards by on a Cloud Infrastructure. This is an alternative to the W3C. Tim Berners-Lee defines the Semantic Web locally run applications. The Google Docs is an as "a web of data that can be processed directly and example of SaaS. In PaaS, users can have flexibility indirectly by machines". The Semantic Web provides a and more choices. The consumer can deploy onto the common framework that allows data to be shared and cloud Infrastructure consumer-created or application reused across application, enterprise, and community created using different programming languages and boundaries. Since the inception of the World Wide tools supported by the provider. The Google Apps Web in 1990 by Tim Berners Lee, it has been a large Engine and Microsoft Azure are some examples of databaes of documents and nowadays the percentage of PaaS. IaaS also provides flexibility and choices. The documents is growing very rapidly. The information consumer can choose networks, processing, storage from these huge documents can be aggregated and and other fundamental computing resources where the inferred quickly, they don’t have much use. Human consumer is able to deploy and run software, which can readers cannot read huge amount of documents include operating sysIJSERtems and applications. Amazon’s retrieved by the previously used search engines based Elastic Compute Cloud (based on Amazon machine on keyword searches. To solve this problem Tim Image) is an example of IaaS. If the cloud computing is Berners Lee’s vision is to transform this World Wide based on Internet and available to the general public, it Web into an intelligent web system or Semantic Web is referred as public cloud.
