Mobile Phones and Cloud Computing
Mobile phones and cloud computing A quantitative research paper on mobile phone application offloading by cloud computing utilization Oskar Hamrén Department of informatics Human Computer Interaction Master’s programme Master thesis 2-year level, 30 credits SPM 2012.07 Abstract The development of the mobile phone has been rapid. From being a device mainly used for phone calls and writing text messages the mobile phone of today, or commonly referred to as the smartphone, has become a multi-purpose device. Because of its size and thermal constraints there are certain limitations in areas of battery life and computational capabilities. Some say that cloud computing is just another buzzword, a way to sell already existing technology. Others claim that it has the potential to transform the whole IT-industry. This thesis is covering the intersection of these two fields by investigating if it is possible to increase the speed of mobile phones by offloading computational heavy mobile phone application functions by using cloud computing. A mobile phone application was developed that conducts three computational heavy tests. The tests were run twice, by not using cloud computing offloading and by using it. The time taken to carry out the tests were saved and later compared to see if it is faster to use cloud computing in comparison to not use it. The results showed that it is not beneficial to use cloud computing to carry out these types of tasks; it is faster to use the mobile phone. 1 Table of Contents Abstract ..................................................................................................................................... 1 Table of Contents ..................................................................................................................... 2 1.

A Coap Server with a Rack Interface for Use of Web Frameworks Such As Ruby on Rails in the Internet of Things
A CoAP Server with a Rack Interface for Use of Web Frameworks such as Ruby on Rails in the Internet of Things Diploma Thesis Henning Muller¨ Matriculation No. 2198830 March 10, 2015 Supervisor Prof. Dr.-Ing. Carsten Bormann Reviewer Dr.-Ing. Olaf Bergmann Adviser Dipl.-Inf. Florian Junge Faculty 3: Computer Science and Mathematics 2afc1e5 cbna This work is licensed under a Creative Commons Attribution-NonCommercial-ShareAlike 4.0 License. http://creativecommons.org/licenses/by-nc-sa/4.0/ Henning Muller¨ [email protected] Abstract We present a Constrained Application Protocol (CoAP) server with a Rack interface to enable application development for the Internet of Things (or Wireless Embedded Internet) using frameworks such as Ruby on Rails. Those frameworks avoid the need for reinvention of the wheel, and simplify the use of Test-driven Development (TDD) and other agile software development methods. They are especially beneficial on less constrained devices such as infrastructure devices or application servers. Our solution supports development of applications almost without paradigm change compared to HTTP and provides performant handling of numerous concurrent clients. The server translates transparently between the protocols and also supports specifics of CoAP such as service and resource discovery, block-wise transfers and observing resources. It also offers the possibility of transparent transcoding between JSON and CBOR payloads. The Resource Directory draft was implemented by us as a Rails application running on our server software. Wir stellen einen Constrained Application Protocol (CoAP) Server mit einem Rack In- terface vor, der Anwendungsentwicklung fur¨ das Internet der Dinge (bzw. das Wireless Embedded Internet) mit Frameworks wie Ruby on Rails ermoglicht.¨ Solche Framworks verhindern die Notwendigkeits, das Rad neu zu erfinden und vereinfachen die Anwen- dung testgetriebener Entwicklung (TDD) und anderer agiler Methoden der Softwareen- twicklung. -

Load Testing of Containerised Web Services
UPTEC IT 16003 Examensarbete 30 hp Mars 2016 Load Testing of Containerised Web Services Christoffer Hamberg Abstract Load Testing of Containerised Web Services Christoffer Hamberg Teknisk- naturvetenskaplig fakultet UTH-enheten Load testing web services requires a great deal of environment configuration and setup. Besöksadress: This is especially apparent in an environment Ångströmlaboratoriet Lägerhyddsvägen 1 where virtualisation by containerisation is Hus 4, Plan 0 used with many moving and volatile parts. However, containerisation tools like Docker Postadress: offer several properties, such as; application Box 536 751 21 Uppsala image creation and distribution, network interconnectivity and application isolation that Telefon: could be used to support the load testing 018 – 471 30 03 process. Telefax: 018 – 471 30 00 In this thesis, a tool named Bencher, which goal is to aid the process of load testing Hemsida: containerised (with Docker) HTTP services, is http://www.teknat.uu.se/student designed and implemented. To reach its goal Bencher automates some of the tedious steps of load testing, including connecting and scaling containers, collecting system metrics and load testing results to name a few. Bencher’s usability is verified by testing a number of hypotheses formed around different architecture characteristics of web servers in the programming language Ruby. With a minimal environment setup cost and a rapid test iteration process, Bencher proved its usability by being successfully used to verify the hypotheses in this thesis. However, there is still need for future work and improvements, including for example functionality for measuring network bandwidth and latency, that could be added to enhance process even further. To conclude, Bencher fulfilled its goal and scope that were set for it in this thesis. -

Building Blocks of a Scalable Web Crawler
Building blocks of a scalable web crawler Marc Seeger Computer Science and Media Stuttgart Media University September 15, 2010 A Thesis Submitted in Fulfilment of the Requirements for a Degree of Master of Science in Computer Science and Media Primary thesis advisor: Prof. Walter Kriha Secondary thesis advisor: Dr. Dries Buytaert I I Abstract The purpose of this thesis was the investigation and implementation of a good architecture for collecting, analysing and managing website data on a scale of millions of domains. The final project is able to automatically collect data about websites and analyse the content management system they are using. To be able to do this efficiently, different possible storage back-ends were examined and a system was implemented that is able to gather and store data at a fast pace while still keeping it searchable. This thesis is a collection of the lessons learned while working on the project combined with the necessary knowledge that went into architectural decisions. It presents an overview of the different infrastructure possibilities and general approaches and as well as explaining the choices that have been made for the implemented system. II Acknowledgements I would like to thank Acquia and Dries Buytaert for allowing me to experience life in the USA while working on a great project. I would also like to thank Chris Brookins for showing me what agile project management is all about. Working at Acquia combined a great infrastructure and atmosphere with a pool of knowledgeable people. Both these things helped me immensely when trying to find and evaluate a matching architecture to this project. -
