kuormituksenjaotus

Kuormituksenjaotus, often translated as load balancing, is a technique used in computer systems and networks to distribute workload across multiple resources. This distribution can improve performance, reliability, and availability of services. When a system experiences high demand, a single server might become overwhelmed, leading to slow response times or outright failure. Kuormituksenjaotus aims to prevent this by spreading the incoming requests or tasks among several interconnected servers or computing units.

The primary goals of kuormituksenjaotus are to ensure that no single resource is overburdened, thereby maximizing throughput and minimizing latency. It also plays a crucial role in fault tolerance; if one server fails, the load balancer can redirect traffic to the remaining healthy servers, ensuring continuous operation of the service. This redundancy is key to maintaining high availability.

There are various algorithms and methods for implementing kuormituksenjaotus. Common approaches include round-robin, where requests are distributed sequentially to each server, and least connection, which directs traffic to the server with the fewest active connections. More sophisticated methods, like weighted round-robin or least response time, consider server capacity or performance metrics. Kuormituksenjaotus can be implemented at different layers of the network stack, from the application layer to the transport layer, depending on the specific requirements.
