Azure DocumentDB is Microsoft’s multi-tenant distributed database service for managing JSON documents at Internet scale. DocumentDB is now generally available to Azure developers. In this paper, we describe the DocumentDB indexing subsystem. DocumentDB indexing enables automatic indexing of documents without requiring a schema or secondary indices. Uniquely, DocumentDB provides real-time consis...

Biodegradation of Orange II, Tropaeolin O, Congo Red, and Azure B in cultures of the white rot fungus, Phanerochaete chrysosporium, was demonstrated by decolarization of the culture medium, the extent of which was determined by monitoring the decrease in absorbance at or near the wavelength maximum for each dye. Metabolite formation was also monitored. Decolorization of these dyes was most exte...

Internet has become pervasive in our daily life and Cloud computing is an emerging paradigm where computing resources are offered over the Internet as scalable, on-demand (Web) services. A company deploying an Internet service needs to invest huge amounts of money on infrastructure needs to serve possible users which is not a problem for large enterprises but when it comes to Small and Medium E...

Increasingly, confidential medical records are being stored in data centers hosted by hospitals or large companies. As sophisticated algorithms for predictive analysis on medical data continue to be developed, it is likely that, in the future, more and more computation will be done on private patient data. While encryption provides a tool for assuring the privacy of medical information, it limi...

The emergence of Cloud Computing offers users and companies the opportunity to utilize elastic resources without the burden of maintaining physical computing centers themselves. Among the popular cloud computing service paradigms today, the Infrastructure-as-a-Service (IaaS) provides virtual computing resources in term of virtual machines (VMs), which users can acquire and release according to ...

The subjects addressed in this thesis are inspired from research problems faced by the Lokad company. These problems are related to the challenge of designing efficient parallelization techniques of clustering algorithms on a Cloud Computing platform. Chapter 2 provides an introduction to the Cloud Computing technologies, especially the ones devoted to intensive computations. Chapter 3 details ...
