A Systematic Review of Web Server Technologies Brixton Hamilton
A Systematic Review of Web Server Technologies Brixton Hamilton Abstract The choice between different web server technologies is an increasingly relevant problem that users must face. This article will outline the features and functionalities that web servers perform, the differences between them, focusing on Apache, IIS, Jetty and Nginx, and how those relate to the requirements of different users. I will analyse the current trends in web server technologies, and suggest how they might continue to change in the future. As the internet rapidly grows and evolves, so must the web server technologies we use to host the websites on it. From merely tens of thousands of sites predominantly using NCSA server technology shortly after the birth of the internet, as of November 2016 there are 171 Million active sites[1], and over time the ever-changing needs of these sites will need to be met by more suitable web servers. The role of the web server in isolation is clear-cut, it must handle HTTP requests. However, outside this it must work with database systems (such as MySQL or MongoDB), serve dynamic content using server-side scripting languages (e.g. PHP or ASP .NET), and deal with the operating system on which it runs (most commonly Linux). Many different web server technologies exist, and when choosing between them, compatibility with the other elements of your server architecture is important. For the past 20 years, the clear-cut leader for active websites has been Apache, an adaptable, open- source server, usually run alongside Linux, PHP and MySQL as part of a ‘LAMP Stack’. -

Fastcgi 1 Fastcgi
FastCGI 1 FastCGI FastCGI es un protocolo para interconectar programas interactivos con un servidor web. FastCGI es una variación de la ya conocida Common Gateway Interface (CGI ó Interfaz Común de Entrada). El principal objetivo de FastCGI es reducir la carga asociada con el hecho de interconectar el servidor web y los programas Common Gateway Interface, permitiéndole a un servidor atender más peticiones a la vez. Ventajas • Independencia del lenguaje utilizado. Libertad de elección de la plataforma de desarrollo: C++, PHP, Perl, Java, entre otros. • Se utiliza un proceso separado. Libertad de elección del servidor web. Facilidad para el tratamiento de errores y depuración. • Es posible la ejecución en host separado. Mayor libertad para configuración del sistema, tanto en el diseño de la red como en la elección de los sistemas operativos. Disminución de la carga de trabajo del servidor principal. En resumen, la libertad de diseño de CGI a la velocidad de un módulo del servidor.. Historia CGI es un protocolo para interconectar aplicaciones externas con servidores web. Las aplicaciones CGI corren en un proceso separado que es creado al inicio de cada petición y es finalizado cuando termina su trabajo. Este modelo de "un nuevo proceso por cada petición" hace que los programas CGI sean muy fáciles de implementar, pero limita la eficiencia y la escalabilidad. En altas cargas, la sobrecarga en el sistema operativo por la creación y destrucción de procesos se torna significativa y limita la escalabilidad. Además, el modelo de procesos CGI limita las técnicas de reutilización de recursos (como ser la reutilización de conexiones a base de datos, caché en memoria, etc). -
Web Service - Is a Standardized Medium,Protocol Or Language to Propagate Communication Between the Client and Server Applications on the World Wide Web
Web service - is a standardized medium,protocol or language to propagate communication between the client and server applications on the World Wide Web. A web service is a software module that is designed to perform a certain set of tasks. Web services are invoked by the user directly or indirectly to provide services to the program/software which is being used as a part of WWW. User may be unaware about such web services. The web services can be searched for over the network and can also be invoked accordingly. When invoked, the web service would be able to provide the functionality to the client, which invokes that web service. Many people think that the internet and the world wide web (WWW) are the same thing. While they are closely linked, they are very different systems. The internet is a huge network of computers all connected together. The world wide web (‘www’ or ‘web’ for short) is a collection of webpages found on this network of computers. Our web browser uses the internet to access the web. The World Wide Web is a way of exchanging information between computers on the Internet, tying them together into a vast collection of interactive multimedia resources. World Wide Web was created by Timothy Berners Lee in 1989 at CERN in Geneva. World Wide Web came into existence as a proposal by him, to allow researchers to work together effectively and efficiently at CERN. Eventually it became World Wide Web. Web architecture Web is a two – tiered architecture. • A web browser display information contents • Web server that transfers information to the client Web services HTML – Hyper text markup language is a document design language not a programming language. -

PERFORMANCE to Improve the Performance Many Things Must Be Considered
CHAPTER FIVE PERFORMANCE To improve the performance many things must be considered. The web portal must avoid the system downtimes. Different types of the web servers are available in the market. Selection of the web server must be done after considering the server limitations and the needs of the web portal. Most of the time some assumptions are made about the client machine, but to make the robust web portal all the Client side limitations (e.g., communication media limitations or availability of devices like printer, speaker, etc.) must be considered. The most important point about the performance is speed optimization which can be achieved by Task scheduling. Different types of tools are available in the market as per the reQuirements for the Load and Performance Measurement. 5 PERFORMANCE 5.1 Introduction The software products undergo several cycles of alpha and beta tests and receive feedback from the users before they are distributed as a final product. The alpha and beta versions are given to the users and users suggest changes, which are reflected in the final product. If the software is fully customized then different modules are prepared and these models are installed on the user machines and users are asked to use the modules. Dynamic Content Caching (Centralized or Distributed) is used to improve the performance. The End-Users may struggle in the identification and manipulation of variables. The Modelling Web Applications Compare the modelling components using non-object oriented languages, and Compare the modelling components using object-oriented languages. Most commonly used model components are Script, Mark up, Style Sheet, Schema, Data languages, and Object-Oriented languages. -
Measurement, Analysis and Performance Improvement of the Apache Web Server ¢¡
Measurement, Analysis and Performance Improvement of the Apache Web Server ¢¡ Yiming Hu Department of Electrical & Computer Engineering & Computer Science University of Cincinnati Cincinnati, OH 45221-0030 [email protected] Ashwini Nanda IBM T.J. Watson Research Center P.O.Box 218 Yorktown Heights, NY 10598 [email protected] Qing Yang Department of Electrical & Computer Engineering University of Rhode Island Kingston, RI 0288 [email protected] Abstract Performance of Web servers is critical to the success of many corporations and organizations. However, very few results have been published that quantitatively study the server behavior and identify the performance bottlenecks. In this paper we measure and analyze the behavior of the popular Apache Web server on a uniprocessor system and a 4-CPU SMP (Symmetric Multi-Processor) system running the IBM AIX operating system. Using the AIX built-in tracing facility and a trace-analysis tool, we obtained detailed information on OS kernel events and overall system activities while running Apache driven by the SPECweb96 and the WebStone benchmarks. We found that on average, Apache spends about 20-25% of the total CPU time on user code, 35-50% on kernel system calls and 25-40% on interrupt handling. For systems with small RAM sizes, the Web server performance is limited by the disk bandwidth. For systems with reasonably large RAM sizes, the TCP/IP stack and the network interrupt handler are the major performance bottlenecks. We notice that Apache shows similar behavior on both the uniprocessor and the SMP systems. After quantitatively identifying the performance bottlenecks, we proposed 8 techniques to improve the performance of Apache. -

Abstract HTTP/2: Analysis and measurements by José Fernando Calcerrada Cano The upgrade of HTTP, the protocol that powers the Internet of the people, was published as RFC on May of 2015. HTTP/2 aims to improve the users experience by solving well- know problems of HTTP/1.1 and also introducing new features. The main goal of this project is to study HTTP/2 protocol, the support in the software, its deployment and im- plementation on the Internet and how the network reacts to an upgrade of the existing protocol. To shed some light on this question we build two experiments. We build a crawler to monitor the HTTP/2 adoption across Internet using the Alexa top 1 million websites as sample. We find that 22,653 servers announce support for HTTP/2, but only 10,162 websites are served over it. The support for HTTP/2 Upgrade is minimal, just 16 servers support it and only 10 of them load the content of the websites over HTTP/2 on plain TCP. Motivated by those numbers, we investigate how the new protocol behaves with the middleboxes along the path in the network. -

José Giovanni Ortega Tostado Asesor externo: Lic. Elisa Becerra Ulloa Organismo Receptor: Tata Consultancy Services, Ltd. Mazatlán, Sinaloa a 11 de diciembre de 2015 AGRADECIMIENTOS Con todo el amor del universo y por sobre todas las cosas, a mi madre y a mi padre, que entre la adversa incertidumbre de verme crecer y evolucionar, resintieron caídas incluso más fuertes que las mías, pero con sus espíritus grandes y sus almas soñadoras, estuvieron siempre ahí para darme la mano, ayudarme a levantar y seguir avanzando. Al espacio, al tiempo y a los acontecimientos que me pusieron el día de hoy en el lugar en el que estoy, pues no quisiera estar en ningún otro lado. A todos mis amigos (tanto a los pasajeros como a los de planta), que no hicieron mi vida más fácil, pero fácilmente la hicieron mucho más llevadera; con su elocuencia humorística y su desdén hacia las cosas que los adultos consideran importantes, hicieron de lo que va de mi existencia, la broma más larga y graciosa que alguien pudiera contarte. Quiero hacer, además, una mención especial a una criatura muy particular (cuyo nombre preferiría no recordar para nada) quien me motivó a reflexionar mis días con mucho más detenimiento, y logró que reviviera (de forma bastante dolorosa) mi ilusión en la vida, en el color, en las flores, en el cielo, en la magia y en el amor.
