This document is a master's thesis that examines how management consulting firms effectively market and sell their services. It also aims to discover differences between large and small consulting firms. The author thanks various individuals who provided support and guidance during the thesis process. A literature review covers theories on transitioning from transactional to relationship marketing and the relationship lifecycle model. The study involved interviews and a questionnaire sent to 25 consulting firms to analyze their marketing methods and the factors influencing their choices. The results supported the theories and found relationship-based marketing is more important for less standardized services, while recommendations and references were the most effective marketing tools. Differences between large and small firms were found to be less significant than their similarities.

This document summarizes Facebook's Data Freeway and Puma systems for real-time analytics. Data Freeway is a scalable data streaming framework that includes components like Scribe, Calligraphus, and Continuous Copier to reliably stream data at high throughput with low latency. Puma is Facebook's real-time aggregation engine that uses Data Freeway to perform aggregations on streaming data as it arrives and store results in HBase, enabling real-time queries with latency of only seconds. It was improved from initial versions Puma2 and Puma3 by supporting more complex aggregations and queries.
Building Mission Critical Messaging System On Top Of HBase
Facebook chose HBase as the storage system for its messaging platform due to HBase's high write throughput, good random read performance, horizontal scalability, and automatic failover. Facebook stores messages, metadata, and search indices in HBase. To improve performance and reliability, Facebook developed the system on a production-stabilized branch of HBase, used shadow testing, added extensive monitoring, and contributed improvements back to the HBase community.
