Interfacing Apache HTTP Server 2.4 with External Applications Met Unix (in the form of Xenix) in 1985 Jeff Trawick Joined IBM in 1990 to work on network software for mainframes Moved to a different organization in 2000 to work on Apache httpd Later spent about 4 years at Sun/Oracle Got tired of being tired of being an employee of too-huge corporation so formed my own too-small company Currently working part-time, coding on other projects, and taking classes Overview Interfacing Apache HTTP Server 2.4 with External Applications Jeff Trawick Huge problem space, so simplify Perspective: \General purpose" web servers, not minimal application containers which implement HTTP \Applications:" Code that runs dynamically on the server during request processing to process input and generate output Possible web server interactions Interfacing Apache HTTP Server 2.4 with External Applications Jeff Trawick Native code plugin modules (uhh, assuming server is native code) Non-native code + language interpreter inside server (Lua, Perl, etc.) Arbitrary processes on the other side of a standard wire protocol like HTTP (proxy), CGI, FastCGI, etc. (Java and \all of the above") or private protocol Some hybrid such as mod fcgid mod fcgid as example hybrid Interfacing Apache HTTP Server 2.4 with External Applications Jeff Trawick Supports applications which implement a standard wire protocol, no restriction on implementation mechanism Has extensive support for managing the application[+interpreter] processes so that the management of the application processes is well-integrated with the web server Contrast with mod proxy fcgi (pure FastCGI, no process management) or mod php (no processes/threads other than those of web server).

  • Load Balancing for Heterogeneous Web Servers
    Load Balancing for Heterogeneous Web Servers Adam Pi´orkowski1, Aleksander Kempny2, Adrian Hajduk1, and Jacek Strzelczyk1 1 Department of Geoinfomatics and Applied Computer Science, AGH University of Science and Technology, Cracow, Poland {adam.piorkowski,jacek.strzelczyk}@agh.edu.pl http://www.agh.edu.pl 2 Adult Congenital and Valvular Heart Disease Center University of Muenster, Muenster, Germany [email protected] http://www.ukmuenster.de Abstract. A load balancing issue for heterogeneous web servers is de- scribed in this article. The review of algorithms and solutions is shown. The selected Internet service for on-line echocardiography training is presented. The independence of simultaneous requests for this server is proved. Results of experimental tests are presented3. Key words: load balancing, scalability, web server, minimum response time, throughput, on-line simulator 1 Introduction Modern web servers can handle millions of queries, although the performance of a single node is limited. Performance can be continuously increased, if the services are designed so that they can be scaled. The concept of scalability is closely related to load balancing. This technique has been used since the beginning of the first distributed systems, including rich client architecture. Most of the complex web systems use load balancing to improve performance, availability and security [1{4]. 2 Load Balancing in Cluster of web servers Clustering of web servers is a method of constructing scalable Internet services. The basic idea behind the construction of such a service is to set the relay server 3 This is the accepted version of: Piorkowski, A., Kempny, A., Hajduk, A., Strzelczyk, J.: Load Balancing for Heterogeneous Web Servers.

Applications used for the analysis of genetic data process large volumes of data with complex algorithms. High performance, flexibility, and a user interface with a web browser are required by these solutions, which can be achieved by using multiple programming languages. In this study, I developed a freely available framework for building software to analyze genetic data, which uses C++, Python, JavaScript, and several libraries. This system was used to build a number of genetic data processing applications and it reduced the time and costs of development. 1.
