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.

Challenges and Opportunities

Data Management in the Cloud

The Islamic state has spread its tentacles in India, penetrating stealthily into the academia, media and politics. The mastermind is Shamsur Ali, a physicist from Bangladesh. To destabilize India, he wants to create a sort of apocalypse, which the 21-year-old Kubha must prevent at any cost, come what may. In a brazen attempt at legitimizing the demolition of one of the most prominent historical structures in India, someone unbelievably, it could be both Hiranyagarbha Bharata, a radical Hindu outfit and the Islamic state resorts to a big deceit. Afsar Fareedi, a linguistic paleontologist, catches the fraud. In the melee, there are three gruesome murders, including that of her father, perhaps to eliminate all traces of a carpet which, Afsar discovers, has a lot hidden in its mysterious motifs. At the centre of all this is a verse composed by the maverick mathematician, Aryabhata, some 1,500 years ago.

To begin afresh, after her broken marriage, Saoli returns to India and starts living in prembajar at the house her grandfather had bought from Bitasta’s father. While cleaning the house, Saoli comes across an old diary, perhaps belonging to Bitasta’s mother, Panchali. The Diary has a very cryptic poem written in dactylic hexameter, the archaic meter of the ancient Greek epics. Aware of the fact that Sairandhri didn’t let her son, Parush, marry Bitasta, even though sairandhri and bitasta’s mother were best of friends, saoli gets in touch with the reckless parush, recently accused in a high-profile IP theft case in the US. As Parush tells Saoli about his heedless and shattered life, his unrequited love affair with Bitasta, his lifelong hatred for his mother and his topsy-turvy corporate career in the US, Saoli unearths the darkest secrets hidden in the cryptic poem all this long. Why didn't Sairandhri want Parush to marry Bitasta? Why was Bitasta the only person she wished to see on her death-bed? Why had she been nothing more than a beautiful but lifeless mural at home? The cryptic poem has the answers. Join Saoli and Parush in their journey to decode the past and discover their real identities, where love can never be chained by stereotypes. It’s time to set love free!
