distributed system

système distribué, également connu sous le nom d’informatique distribuée, est un système avec plusieurs composants situés sur différentes machines qui communiquent et coordonnent les actions afin d’apparaître comme un seul système cohérent à l’utilisateur final.

systèmes distribués puissent parfois être obscurs, ils présentent généralement trois caractéristiques principales : tous les composants fonctionnent simultanément, il n’y a pas d’horloge globale et tous les composants tombent en panne indépendamment les uns des autres

distributed system is a collection of computers that work together to form a single computer for the end-user

these distributed machines have one shared state and operate concurrently

fail independently without damaging the whole system

linked by a network to share information, communicate, and exchange information easily.

Distributed systems must have a shared network to connect its components, which could be connected using an IP address or even physical cables.

user must be able to communicate with any machine without knowing it is only one machine.

important part of distributed systems is the CAP theorem, which states that a distributed data store cannot simultaneously be consistent, available, and partition tolerant

Decentralized is essentially distributed on a technical level, but usually a decentralized system is not owned by a single source.

distributed system is a collection of independent components located on different machines that share messages with each other in order to achieve common goals.

distributed system will appear as if it is one interface or computer to the end-user

together, the system can maximize resources and information while preventing failures, as if one system fails, it won’t affect the availability of the service.

distributed system, also known as distributed computing, is a system with multiple components located on different machines that communicate and coordinate actions in order to appear as a single coherent system to the end-user.

distributed system is a computing environment in which various components are spread across multiple computers (or other computing devices) on a network. These devices split up the work, coordinating their efforts to complete the job more efficiently than if a single device had been responsible for the task.

Distributed systems are commonly defined by the following key characteristics and features:

Scalability: The ability to grow as the size of the workload increases is an essential feature of distributed systems, accomplished by adding additional processing units or nodes to the network as needed. Concurrency: Distributed system components run simultaneously. They’re also characterized by the lack of a “global clock,” when tasks occur out of sequence and at different rates. Availability/fault tolerance: If one node fails, the remaining nodes can continue to operate without disrupting the overall computation. Transparency: An external programmer or end user sees a distributed system as a single computational unit rather than as its underlying parts, allowing users to interact with a single logical device rather than being concerned with the system’s architecture. Heterogeneity: In most distributed systems, the nodes and components are often asynchronous, with different hardware, middleware, software and operating systems. This allows the distributed systems to be extended with the addition of new components. Replication: Distributed systems enable shared information and messaging, ensuring consistency between redundant resources, such as software or hardware components, improving fault tolerance, reliability and accessibility.

distributed system in its most simplest definition is a group of computers working together as to appear as a single computer to the end-user
