Mobile devices and accessing the web have become essential in our daily lives. However, their limitations in terms of both hardware such as the battery, and software capabilities can affect the user experience such as battery drain. There are some best practices for the web page design that are shown to affect the downloading time of web pages. In this study, we report our experience in applying these practices to see their effect on energy saving. We propose two techniques: (1) concatenating external script and stylesheet files and (2) minifying external script and stylesheets that can be used to transcode web pages to improve energy consumption on the client-side and therefore improve the battery life. We present our experimental architecture, implementation, and a systematic evaluation of these two techniques. The evaluation results show that the proposed techniques can achieve approximately 12% processor energy-saving and 4% power saving in two different client types, 13% improvement in a typical laptop battery life, and 4% improvement in a typical mobile phone battery life.

Özet-Günümüzde esnek, güvenilir ve duyarlı (responsive) yazılımlara olan talebin artması ve bu talebe karşılık verebilen internet altyapısının olması yeni nesil bulut uygulamalarının gelişmesine öncülük etmiştir. Bunun sonucunda, bulut tabanlı dağıtık web uygulamalarının birlikte çalışarak oluşturduğu mikroservis tabanlı mimari popülerlik kazanmıştır. Mikroservis tabanlı mimari oldukça yeni olup bu mimariyi kullanarak yazılım geliştiren firmaların kültürlerini değiştirme gerekliliği doğmuştur. Ancak, literatürde mikroservis tabanlı mimaride analiz ve tasarım konusunda uygulanan yöntemleri ele alan çalışma sayısı çok azdır. Bu çalışmada, Türkiye'deki yazılım organizasyonlarının mikroservis tabanlı proje geliştirirken başvurdukları analiz ve tasarım yöntemlerini ele alan bir anket düzenlenmiştir. Anket sonuçları, mikroservis tabanlı proje konusunda tecrübesi olan yazılım organizasyonlarının analiz ve tasarım konusundaki bakış açılarını ortaya çıkarmaktadır. Elde edilen sonuçlar mikroservis kullanan organizasyonlar ile ilgili genel tabloyu göstermekte ve araştırmacılar için çalışma yapılabilecek konuları önermektedir.

The rapidly developing internet infrastructure together with the advances in software technology has enabled the development of cloud-based modern web applications that are much more responsive, flexible, and reliable compared to traditional monolithic applications. Such modern applications require new software design paradigms and architectures. Microservice-based architecture (MSbA), which aims to create small, isolated, loosely-coupled applications that work in cohesion, becoming widespread as one of these approaches. MSbA allows the developed applications to be deployed and maintained separately, as well as scaled on demand. However, there is no de facto method for the analysis and design of systems for these architectures. In this paper, we compared the usefulness of the object-oriented (OO) and event-oriented (EO) approaches for analyzing and designing MS-based systems. More specifically, we performed an exploratory case study to analyze, design, and implement a software application dealing with the 'application and evaluation process of graduate students at IzTech'. This paper discusses the results of this case study. We observe that the EO approaches have significant advantages with respect to the OO approaches.Keywords-microservices, event-driven process chains, eEPC, event-oriented analysis, cloud 244 2021 47th Euromicro Conference on Software Engineering and Advanced Applications (SEAA)
