Cooperative storage cloudA cooperative storage cloud is a decentralized model of networked online storage where data is stored on multiple computers (nodes), hosted by the participants cooperating in the cloud. For the cooperative scheme to be viable, the total storage contributed in aggregate must be at least equal to the amount of storage needed by end users. However, some nodes may contribute less storage and some may contribute more. There may be reward models to compensate the nodes contributing more.
In-memory processingIn computer science, in-memory processing (PIM) is a computer architecture for processing data stored in an in-memory database. In-memory processing improves the power usage and performance of moving data between the processor and the main memory. Older systems have been based on disk storage and relational databases using Structured Query Language, which are increasingly regarded as inadequate to meet business intelligence (BI) needs.
Cloud collaborationCloud collaboration is a method of sharing and co-authoring s via cloud computing, whereby documents are uploaded to a central "cloud" for storage, where they can then be accessed by other users. Cloud collaboration technologies allow users to upload, comment and collaborate on documents and even amend the document itself, evolving the document. Businesses in the last few years have increasingly been switching to use of cloud collaboration.
Multi-access edge computingMulti-access edge computing (MEC), formerly mobile edge computing, is an ETSI-defined network architecture concept that enables cloud computing capabilities and an IT service environment at the edge of the cellular network and, more in general at the edge of any network. The basic idea behind MEC is that by running applications and performing related processing tasks closer to the cellular customer, network congestion is reduced and applications perform better.
Dew computingDew computing is an information technology (IT) paradigm that combines the core concept of cloud computing with the capabilities of end devices (personal computers, mobile phones, etc.). It is used to enhance the experience for the end user in comparison to only using cloud computing. Dew computing attempts to solve major problems related to cloud computing technology, such as reliance on internet access. Dropbox is an example of the dew computing paradigm, as it provides access to the files and folders in the cloud in addition to keeping copies on local devices.
HadoopHadoop est un framework libre et open source écrit en Java destiné à faciliter la création d'applications distribuées (au niveau du stockage des données et de leur traitement) et échelonnables (scalables) permettant aux applications de travailler avec des milliers de nœuds et des pétaoctets de données. Ainsi chaque nœud est constitué de machines standard regroupées en grappe. Tous les modules de Hadoop sont conçus selon l'idée que les pannes matérielles sont fréquentes et qu'en conséquence elles doivent être gérées automatiquement par le framework.
Docker (logiciel)Docker est une plateforme permettant de lancer certaines applications dans des conteneurs logiciels lancée en 2013. Selon la firme de recherche sur l'industrie 451 Research, « Docker est un outil qui peut empaqueter une application et ses dépendances dans un conteneur isolé, qui pourra être exécuté sur n'importe quel serveur ». Il ne s'agit pas de virtualisation, mais de conteneurisation, une forme plus légère qui s'appuie sur certaines parties de la machine hôte pour son fonctionnement.
Fédération (informatique)Une fédération est un groupe de fournisseurs informatique ou de réseaux qui s'accordent sur des normes de fonctionnement (« physique » ou/et logiciel) de manière collective. Le terme peut être utilisé pour décrire l'interfonctionnement de deux réseaux de télécommunications distincts, formellement déconnectés, qui peuvent avoir des structures internes différentes. Le terme cloud fédéré fait référence à la facilitation de l'interconnexion de deux ou plusieurs clouds informatiques géographiquement séparés.
Active usersActive users is a software performance metric that is commonly used to measure the level of engagement for a particular software product or object, by quantifying the number of active interactions from users or visitors within a relevant range of time (daily, weekly and monthly). The metric has many uses in software management such as in social networking services, online games, or mobile apps, in web analytics such as in web apps, in commerce such as in internet banking and in academia, such as in user behavior analytics and predictive analytics.
