Book Description
With the proliferation of Software-as-a-Service (SaaS) offerings, it is becoming increasingly important for individual SaaS providers to operate their services at a low cost. This book investigates SaaS from the perspective of the provider and shows how operational costs can be reduced by using “multi tenancy,” a technique for consolidating a large number of customers onto a small number of servers. Specifically, the book addresses multi tenancy on the database level, focusing on in-memory column databases, which are the backbone of many important new enterprise applications. For efficiently implementing multi tenancy in a farm of databases, two fundamental challenges must be addressed, (i) workload modeling and (ii) data placement. The first involves estimating the (shared) resource consumption for multi tenancy on a single in-memory database server. The second consists in assigning tenants to servers in a way that minimizes the number of required servers (and thus costs) based on the assumed workload model. This step also entails replicating tenants for performance and high availability. This book presents novel solutions to both problems.

Book Description
This book explores the political economics and cultural politics of social media news sharing, investigating how it is changing journalism and the news media internationally. News sharing plays important economic and cultural roles in an attention economy, recommending the stories audiences find valuable, making them more visible, and promoting the digital platforms that are reshaping our media ecologies. But is news sharing a force for democracy, or a sign of journalism’s declining power to set news agendas? In Sharing News Online, Tim Dwyer and Fiona Martin analyse the growth of commendary culture and the business of social news, critique the rise of news analytics and dissect virality online. They reveal that surprisingly, we share political stories more highly than celebrity news, and they probe how deeply affect drives our sharing behaviour. In mapping the contours of a critical digital media phenomenon, this book makes essential reading for scholars, journalists and media executives.

Book Description
When Kaumudi Marathé moved to the US from India, she never thought she'd be a famous chef, food writer and unofficial spokesperson for Indian cuisine abroad. Shared Tables is her memoir of an unlikely career enriched and shaped by family history, stories, memorable meals and staunch friendships. In this book, Kaumudi explores her roots in the Konkanastha and Saraswat clans, recalling her immersion in their classic Marathi cuisines. Her peripatetic childhood, spent in places as diverse as Poona, Canada, Nagaland, Hyderabad and Wales, let her taste and savour the many flavours that came her way. As an adult, her choice of journalism as a profession took her to the Bombay of the heady 1980s and '90s, where she met the challenges of adulthood and authorship, navigating marriage and deadlines, while constantly exploring the many offerings of the city. Her eventual move to LA, a city that encouraged her to dream of an entirely new way of living, enabled her to set up the first Indian cooking school in the US, Un-Curry, alongside her restaurant and catering company. Throughout her journey, Kaumudi shared tables with a variety of friends and family, all of them laughing and eating together and helping one another grow into their present selves. Via anecdotes, recipes and photographs, Kaumudi Marathé illustrates how love and food build a shared connection amongst diverse cultures, countries, backgrounds and professions. Shared Tables is a feast for the mind, heart and soul.

Book Description
Cloud computing has emerged as a successful paradigm of service-oriented computing and has revolutionized the way computing infrastructure is used. This success has seen a proliferation in the number of applications that are being deployed in various cloud platforms. There has also been an increase in the scale of the data generated as well as consumed by such applications. Scalable database management systems form a critical part of the cloud infrastructure. The attempt to address the challenges posed by the management of big data has led to a plethora of systems. This book aims to clarify some of the important concepts in the design space of scalable data management in cloud computing infrastructures. Some of the questions that this book aims to answer are: the appropriate systems for a specific set of application requirements, the research challenges in data management for the cloud, and what is novel in the cloud for database researchers? We also aim to address one basic question: whether cloud computing poses new challenges in scalable data management or it is just a reincarnation of old problems? We provide a comprehensive background study of state-of-the-art systems for scalable data management and analysis. We also identify important aspects in the design of different systems and the applicability and scope of these systems. A thorough understanding of current solutions and a precise characterization of the design space are essential for clearing the "cloudy skies of data management" and ensuring the success of DBMSs in the cloud, thus emulating the success enjoyed by relational databases in traditional enterprise settings.
