Dreifikerfis

Dreifikerfis (distributed system) is a collection of independent computers that appear to users as a single system. They coordinate by exchanging messages and sharing resources to achieve common goals, often to improve scalability, fault tolerance, and performance.

A central feature is concurrency without a single shared memory or clock. Nodes may fail independently, and the system must continue operating, possibly with degraded performance. Openness, scalability, and ability to evolve are also sought characteristics.

Common architectures include client–server, where clients request services from servers, and peer-to-peer, where nodes act as both clients and servers. Middleware and architectures such as service-oriented, microservices, or actor models help manage communication, state, and failures. Communication usually relies on networks, protocols, message queues, or remote procedure calls.

Data management in dreifikerfis often uses replication and partitioning to balance availability and locality. Consistency models vary; some systems aim for strong consistency, others allow eventual consistency. The CAP theorem notes trade-offs between consistency, availability, and partition tolerance in distributed environments.

Practical applications include the World Wide Web, distributed file systems, cloud services, and large-scale databases. Key challenges are partial failures, network partitions, heterogeneity of hardware and software, latency, and security.
