  • 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.
