MongoDB Performance In The Cloud

Web applications are growing at a staggering rate every day. As web applications keep getting more complex, their data storage requirements tend to grow exponentially. Databases play an important role in the way web applications store their information. Mongodb is a document store database that does not have strict schemas that RDBMs require and can grow horizontally without performance degradation. MongoDB brings possibilities for different storage scenarios and allow the programmers to use the database as a storage that fits their needs, not the other way around. Scaling MongoDB horizontally requires tens to hundreds of servers, making it very difficult to afford this kind of setup on dedicated hardware. By moving the database into the cloud, this opens up a possibility for low cost virtual machine instances at reasonable prices. There are many cloud services to choose from and without testing performance on each one, there is very little information out there. This paper provides benchmarks on the performance of MongoDB in the cloud

Reducing the deforestation of the Amazon through farming system intensification

The Amazon has become the last Far West of the planet. Today, the attention is focused on some sectors in which the region plays a major role: the mineral richness of the soil - especially hydro fuels - biodiversity, climate change and the coca plantations. Big portions of the huge forest have been transferred to the agricultural sector. The vigour of colonisation has transformed the Amazon into a major grain and meat provider with relevant environmental impact in terms of deforestation. This increasing demand for food is changing the context of Amazonian agriculture. Big ranches, which are occupying around 80% of the deforested land and initially conceived as mere land investments, are seeing agriculture as a means to raise their value. At the same time, the world has changed. Unsustainable environmental and social practices which were common a few years ago are no longer acceptable. Accordingly, new production strategies, protecting the environment and human work, are starting to spread. (Résumé d'auteur

An Ontology based System for Cloud Infrastructure Services Discovery

The Cloud infrastructure services landscape advances steadily leaving users in the agony of choice. As a result, Cloud service identification and discovery remains a hard problem due to different service descriptions, non standardised naming conventions and heterogeneous types and features of Cloud services. In this paper, we present an OWL based ontology, the Cloud Computing Ontology (CoCoOn) that defines functional and non functional concepts, attributes and relations of infrastructure services. We also present a system...Comment: Accepted as an invited paper by Collaboratecom 201
