Abstract The key concept of Web services is to make both inter- and intra-application integration pos- sible in a way that the integration does not depend on the platform or implementation of the service customer or provider. Since the information about Web services and their providers is usually managed in a central UDDI1 registry and the present UDDI standard does not offer a mechanism for the automatic actualization of the Web service information, it is often inac- curate or outdated[1]. This work presents a concept for solving these problems. Moreover, it allows to optimize the Web service application process by adopting a Pull/Push technique and Publish/Subscribe Model based search and management system for Web services. Furthermore, the system searches proactively for new Web services and selects the appropriate service for the service customer. This improves significantly the reaction time and the performance of the Web service application process. The following main contributions build up the core of the work: • The current UDDI standard is extended by a Publish/Subscribe mechanism • Service customers can use the Publish/Subscribe mechanism to register themselves for certain Web services • Reduction of response time for service customers by automatic searching for new Web services by the service broker (in our case SerumS) • Improved correctness and completeness of the search result • Notification about new Web services and changes to the service customers through the service provider • Avoidance of inconsistent data by automatic update of the Web service information The aim of this work is to use the “Publish-Subscribe Notification for Web services”[2] specifi- cation for realizing the Publish/Subscribe mechanism, so that the result can be considered as a replacement for a UDDI registry. The proof of concept (PoC), which results from this work, has in addtion to the traditional functionalities of a UDDI registry also the features mentioned above. 1Universal Description Discovery and Integration ii Zusammenfassung Das Schlusselkonzept¨ von Web Services liegt darin, sowohl Unternehmens-ubergreifende¨ als auch -interne Anwendungsintegration auf die Art und Weise zu erm¨oglichen, dass die Integration weder von der Plattform noch von der Implementierung des Service Customer oder Provider abh¨angt. Da die Informationen zu den Web Services und deren Provider in einer zentralen UDDI Registry verwaltet werden und der aktuelle UDDI Standard keinen Mechanismus zur automatischen Aktualisierung der Web Service Informationen besitzt, sind diese sehr oft un- genau und “out-of-date”[1]. In dieser Arbeit wird ein Konzept zur L¨osung dieser Probleme vorgestellt, welches daruber¨ hinaus den Web Service Anwendungsprozess durch den Einsatz eines auf Pull/Push-Technik und Publish/Subsribe-Modell basierten Such- und Managementsystems optimiert. Außerdem sucht das System proaktiv nach neuen Web Services und w¨ahlt fur¨ den Service Customer den passenden Service. Dies verbessert significant die Reaktionszeit und die Performanz des Web Service Anwendungsprozesses. Die folgenden Hauptbeitr¨age bilden den Kern der Arbeit: • Der aktuelle UDDI Standard wird um den Publish/Subscribe Mechanismus erweitert • Service Customer k¨onnen den Publish/Subscribe Mechanismus benutzen, um sich fur¨ bes- timmte Services zu registrieren. • Reduktion der Antwortzeit fur¨ Service Customer durch automatisches Suchen nach neuen Web Services durch den Service Broker (in unserem Fall SerumS) • Verbesserte Korrektheit und Vollst¨andigkeit des Suchergebnisses. • Die Service Customer werden von den Service Provider uber¨ neue Web Services und ihre Anderungen¨ benachrichtigt. • Vermeidung von inkonsistenten Daten durch automatisches Update der Web Service In- formationen. Das Ziel dieser Arbeit ist das Benutzen der “Publish-Subscribe Notification for Web services”[2] Spezifikation fur¨ die Realisierung des Publish/Subscribe Mechanismus, so dass das Ergebnis als Ersatz fur¨ die UDDI Registry betrachtet werden kann. Das “Proof of Concept (PoC)” besitzt zus¨atzlich zu den traditionellen Fuktionalit¨aten einer UDDI Registry auch die gerade erw¨ahnten Neuerungen. iv Acknowledgement First of all, I would like to thank Univ-Prof. Dr. Eike Jessen and Univ.-Prof. Dr. Martin Bichler for supervising this thesis and giving me the full freedom to work on it.

  • Web Hosting Service Participants Meeting
    1/13/11 Web Hosting Service" Participants meeting http://oit.ncsu.edu/web-hosting-service Presented by: Office of Information Technology January 13, 2011 Introduction to Web Hosting Service Over a year ago, OIT began investigating how to deliver web services in a manner similar to those in the commercial sector. Our current web service, while stable and robust, is unable to provide campus users with the flexibility of more packages/applications and economy of scale that many of us desire to use for our web presence. OIT has been piloting a model of this service with 5 participating units, all who have used the service to varying degrees. OIT is now ready to expand this pilot into a beta by increasing our customer base and monitoring the administrative, technical and support load as we prepare to go into production mode. 1 1/13/11! What makes up the service? Service is running on the OIT production blade farm and the Linux-based operating environment is running atop a VMware infrastructure. Customers have access to cPanel and Fantastico to manage their site(s). WRAP-authentication, InForm availability; two levels of service: Lite and Full. We have tested the service on external machines (hosted by a commercial provider) and are now testing running internally. What’s different about web hosting? • Initial account comes with 10 GB of space w/option to purchase more in 10 GB increments • cPanel control panel to administer your site(s) • Fantastico system that makes installing scripts easier • Unlimited databases (mySQL) • More features and applications for your web presence • Two levels of service (Lite and Full) We continue to offer • NC State hosted URLs • Nightly back-ups • Unlimited bandwidth 2! 1/13/11!

  • Hosting Plan Fulfills My Website Needs? Well, Let’S Take a Look
    GETTING WEB READY Introduction to Web Hosting You have a website in place now, so GET YOUR WEBSITE HOSTED! 4 Learning Objectives: • Define web hosting • Define web server • Identify factors that influence web hosting decisions IF YOU WANT YOUR WEBSITE To not only be easily accessible but also run efficiently At all times, you need to publish along with a Webhosting service provider. User User User User Internet server Website files are hosted on servers. The servers 'serve' those files to individual computer users upon request. The internet makes it all possible. 5 WHAT IS WEB HOSTING • Web hosting allows you to post a website or webpage onto Internet. • A web host, or web hosting service provider, provides technologies & services needed for website or webpage to be viewed in Internet. • Websites are hosted, or stored, on servers. • Hosting companies usually require you to own domain in order to host with them. 6 BUT HOW DO I KNOW which hosting plan fulfills my website needs? Well, let’s take a look... 7 SHARED HOSTING It is not only the most popular, but also the most affordable web hosting plan. The web server is shared by multiple websites in a common hosting environment. They share the same IP address and server resources (disk space, RAM, bandwidth, uptime, etc). 8 V IRTUAL PRIVATE SERVER (VPS) HOSTING In this hosting plan, a server is divided into multiple virtual units and each unit acts as a dedicated server that hosts only one website. 9 DEDICATED HOSTING Here, the user rents the entire server to host his/her website.

  • Demystifying Cloud Computing
    DATA MINING inside their own datacenters. This structure gives users the flex- ibility to scale up and down in response to market fluctuations. For instance, a business enters the market with a new website that is initially unknown to customers, but eventually becomes popular with hundreds of thousands of requests per day. With cloud computing, businesses may start with a minimum set of IT resources and allocate additional services during peak times. Moreover, website owners can easily dispose unused IT resources during non-peak/recession times enabling them to reduce overall costs. Typically, cloud computing adopts the concept of utility com- puting to give users on-demand access to computing resources in a very similar way to accessing traditional public utilities such as electricity, water, and natural gas. In this framework, clients follow a pay-as-you-go model that provides access to as much or as little computing resources as needed whenever needed Demystifying from anywhere. Hence, organizations are no longer obliged to plan ahead and highly invest in computing resources to accom- plish business goals. Cloud History of Cloud Computing The idea of cloud computing is not actually new as it goes back several decades. It was pioneered by Professor John McCarthy, a well-known computer scientist who initiated time- Computing sharing in late 1957 on modified IBM 704 and IBM 7090 com- puters [3]. McCarthy expected that some corporations would Qusay F.

  • For Many People, a Search Engine, Not a Phone Directory, Is Where They Look for Information First
    For many people, a search engine, not a phone directory, is where they look for information first. They assume that they’ll find what they need online, and if they can’t, that it doesn’t exist. To connect with these potential donors, volunteers, and partners, you need a website. Your website doesn’t need to be complicated. To start, you simply need a place where people can learn about your mission and programs, see how to contact you, and make donations. The process of deciding what information you need on your website and drafting it can be difficult, especially if a group is responsible for creating the content. A few tips to make it easier: Start simple. Every page you add is a page you’ll need to update and maintain. Browse other websites. See what pages they have and how the pages are organized. Focus on what people will be looking for on your website. Often this is different than what you want them to read on your website. Avoid jargon and academic language, and write so that people can understand your content easily. (Tools that can help you assess if your content is easy to read include Edit Central (http://www.editcentral.com/gwt1/EditCentral.html), StoryToolz Readability Statistics (http://storytoolz.com/readability), Readability-Score.com (http://www.readability- score.com/).) List your staff and their contact information. Put your donate button and newsletter sign-up form in a prominent place. This list will give you a good start, but it’s by no means complete. A good additional resource is Abstract Edge’s Failing to Plan Is Planning to Fail (http://info.abstractedge.com/nonprofit-ebook).

  • A Platform for Learning Internet of Things
    International Conference e-Learning 2014 A PLATFORM FOR LEARNING INTERNET OF THINGS Zorica Bogdanović, Konstantin Simić, Miloš Milutinović, Božidar Radenković and Marijana Despotović-Zrakić Department for e-Business, Faculty of Organizational Sciences, University of Belgrade Jove Ilića 154, Belgrade, Serbia ABSTRACT This paper presents a model for conducting Internet of Things (IoT) classes based on a web-service oriented cloud platform. The goal of the designed model is to provide university students with knowledge about IoT concepts, possibilities, and business models, and allow them to develop basic system prototypes using general-purpose micro- devices and a cloud and service infrastructure. The model was based on a cloud infrastructure deployed at the E-Business Department at the Belgrade University, and some implementation details are given. The model was tested and evaluated in a pilot course. KEYWORDS Internet of Things, Raspberry Pi, Arduino, Cloud Computing 1. INTRODUCTION The expression “Internet of Things” describes the existence of a number of various things or objects like tags, sensors, actuators, mobile devices, capable of cooperating in order to achieve a common goal (Atzori et al. 2010). Such intelligent devices can take a number of forms and roles, and the composition of such systems can be adjusted dynamically, according to the needs of the users. This gives IoT an almost unlimited area of application within both business and industry (process management, intelligent transport, automation), as well as in homes and public environments (smart homes, e-health, assisted learning). The term IoT encompasses an unbounded, growing set of devices and technologies, and as the IoT technologies gain traction globally, the need for experts that combine knowledge from various technical fields increases.
