  • Fiz: a Component Framework for Web Applications
    Fiz: A Component Framework for Web Applications John K. Ousterhout Department of Computer Science Stanford University Abstract Fiz is a framework for developing interactive Web applications. Its overall goal is to raise the level of programming for Web applications, first by providing a set of high-level reusable components that simplify the task of creating interactive Web applications, and second by providing a framework that encourages other people to create addi- tional components. Components in Fiz cover both the front-end of Web applications (managing a browser-based user interface) and the back end (managing the application's data). Fiz makes it possible to create components that encapsulate complex behaviors such as Ajax-based updates, hiding many of the Web's complexities from applica- tion developers. Because of its focus on components, Fiz does not use mechanisms such as templates and model- view-controller in the same way as other frameworks. ger and more useful structures. We will release Fiz in 1 Introduction open-source form and hope to build a user community Although the World-Wide Web was initially conceived that creates an ever-increasing set of interesting com- as a vehicle for delivering and viewing documents, its ponents, which will make it dramatically easier to cre- focus has gradually shifted from documents to applica- ate applications that advance the state-of-the-art in Web tions.

  • The Role of Responsive Design in Web Development
    Webology, Volume 14, Number 2, December, 2017 Home Table of Contents Titles & Subject Index Authors Index The Role of Responsive Design in Web Development Fernando Almeida Centre for Innovation, Technology and Entrepreneurship, INESC TEC, Porto, Portugal. E-mail: [email protected] José Monteiro Higher Polytechnic Institute of Gaya, ISPGaya, V.N.Gaia, Portugal. E-mail: [email protected] Received October 12, 2017; Accepted December 25, 2017 Abstract Responsive design allows software developers to build a Web page that can dynamically adapt to the size of the devices. This development philosophy enables the rendering of Web pages in a fast and optimized way, ensuring a good user experience on mobile devices, tablet and desktop. In the scope of this study, we intend to explore the main advantages and limitations associated with responsive Web design. We adopted a quantitative approach based on a questionnaire filled by 181 professionals in the industry that allowed us to identify the reasons that lead software developers to the adoption of the responsive design and also address the limitations felt by them. The results obtained indicate that offering a good user experience and increasing accessibility stands out as being the most important advantages. On the other hand, the main limitations include the compatibility with older Web browsers, the higher loading time and the difficulties in optimizing user experience. Finally, it was found that the perception of the advantages and limitations of responsive design is distinct for professionals with more professional experience in the field and for freelancer developers.

Most of the industries, irrespective of their size are moving towards Cloud-based solutions. Cloud computing has been buzzing around the industry because of its characteristics such as low-cost storage, on-demand computing resources, pay as you use, availability of data at any time and any place and ease in maintenance, etc. Cloud technology provides high availability, scalability, elasticity, pay as you go, and on-demand computing resources. There are various Cloud service providers available in the market such as AWS, Microsoft Azure, Google Cloud, etc. Here, we are using AWS as a cloud service provider and apply a different approach to develop a web portal, which is different from the traditional approach. This paper demonstrates how to develop any web application, provide multiple interfaces to it, and how to choose appropriate services from Amazon Web Services for an application. Key Words: Cloud Computing, Scalability, Elasticity, Web Portal, Amazon Web Services 1. INTRODUCTION 1.1 Web Development Web Development comprehensively refers to the tasks associated with developing online portals for hosting via the internet or intranet. The web development process incorporates website composition, web content development, customer-side/server- side scripting, system security setup, and other associated tasks.
