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. -

We welcome reader comments about anything in the manuscript - other than typos and other simple mistakes. These will be cleaned up during production of the book by copyeditors and proofreaders. https://forums.manning.com/forums/vertx-in-action welcome Thank you for purchasing the MEAP of Vert.x in Action. Asynchronous and reactive applications are an important topic in modern distributed systems, especially as the progressive shift to virtualized and containerized runtime environments emphasize the need for resource efficient, adaptable and dependable application designs. Asynchronous programming is key to maximizing hardware resource usage, as it allows dealing with more concurrent connections than with the traditional blocking I/O paradigms. Services need to cater for workloads that may drastically change throughout from one hour to the other, hence we need to design code that naturally supports horizontal scalability. Last but not least, failure is inevitable when we have services interacting with other services over the network. Embracing failure is key for designing dependable systems. Assemble asynchronous programming, horizontal scalability, resilience and you have what we call today reactive applications, which can also be summarized without marketing jargon as “scalable and dependable applications”. That being said there is no free lunch and the transition to writing asynchronous and reactive applications is difficult when you have a background in more traditional software stacks. Grokking asynchrony in itself is difficult, but the implications of scalability and resilience on the design of an application are anything but trivial. -
