Komparativna analiza Java i .NET Web servisa

Abstract

Ovaj rad predstavlja rezultat istraživanja sprovedenog sa ciljem da se postavi formalni model arhitekture Web servisa i izvrši komparativna analiza performansi Web servisa realizovanih korišćenjem dve vodeće platforme za razvoj softvera - Java i .NET. Sa ciljem davanja pune slike o standardnoj arhitekturi Web servisa, njihove teorijske i tehnološke osnove su opisane preko formalnog modela, predstavljenog UML dijagramom. Nakon toga dat je opis uočenih elemenata i veza u formalnom modelu, sa posebnim fokusom na ulogu elemenata i formulaciju njihovih međusobnih zavisnosti. Posmatrane platforme za razvoj softvera prikazane su kroz tehnologije za implementaciju Web servisa, i prezentovani su rezultati poređenja različitih tehnologija unutar svake od platformi. Korišćenjem metoda dinamičke analize i softverskih profajlera, vršen je monitoring aplikacija i analiza njihovih performansi. Posmatrane platforme su upoređene sa aspekta izvršavanja Web servisa u JAX-WS i WCF implementacijama, i predstavljeni su dobijeni rezultati. Na kraju je prikazana diskusija u kojoj su objašnjene uočene prednosti i mane Java i .NET realizacija Web servisa.

This paper is the result of research carried out in order to define a formal model of Web services architecture and perform a comparative analysis of performance of the web services implemented using two leading software development platforms - Java and. NET framework. With the goal of providing a full picture of the standard Web services architecture, their theoretical and technological basis are described by formal model, presented by UML diagram. Furthermore, the observed elements and relationships from the formal model are elaborated, with focus on roles of elements and formulation of their interdependence. The considered software development platforms are presented through Web services development technologies available in each of them, and the results of comparison of different technologies inside each platform. By using dynamic analysis methods and software profilers, application monitoring and performance analysis were executed. The considered platforms are compared in terms of execution of web services in JAX-WS and WCF implementations, and the results are presented. At the end, there is the discussion which explains the perceived advantages and disadvantages of Java and. NET Web services implementation.
