Plate-forme (informatique)En informatique, une plateforme ou plate-forme est un environnement permettant la gestion ou l'utilisation de services (ou logiciels) applicatifs.
Central processing unitA central processing unit (CPU)—also called a central processor or main processor—is the most important processor in a given computer. Its electronic circuitry executes instructions of a computer program, such as arithmetic, logic, controlling, and input/output (I/O) operations. This role contrasts with that of external components, such as main memory and I/O circuitry, and specialized coprocessors such as graphics processing units (GPUs). The form, design, and implementation of CPUs have changed over time, but their fundamental operation remains almost unchanged.
Data processing unitA data processing unit (DPU) is a programmable computer processor that tightly integrates a general-purpose CPU with network interface hardware. Sometimes they are called "IPUs" (for "infrastructure processing unit") or "SmartNICs". They can be used in place of traditional NICs to relieve the main CPU of complex networking responsibilities and other "infrastructural" duties; although their features vary, they may be used to perform encryption/decryption, serve as a firewall, handle TCP/IP, process HTTP requests, or even function as a hypervisor or storage controller.
Platform as a servicePlatform as a service (PaaS), ou plate-forme en tant que service, est l'un des types d'infonuagique (Cloud Computing), principalement destiné aux développeurs ou aux entreprises de développement, où : l'entité cliente (développeurs ou entreprise) maintient les applications proprement dites; le fournisseur cloud maintient la plate-forme d'exécution de ces applications : le matériel du ou des serveurs (la carte mère, la mémoire vive...), les logiciels de base (c'est-à-dire le ou les systèmes d'exploitation, le ou les moteurs de bases de données.
