Kuormitusjakelu

Kuormitusjakelu, in Finnish, refers to load balancing. It is a technique used in computing and networking to distribute incoming network traffic across multiple backend servers. The primary goal of kuormitusjakelu is to optimize resource utilization, maximize throughput, minimize response time, and avoid overloading any single resource.

A kuormitusjakelu device or software acts as a "traffic cop," receiving incoming requests and forwarding them to a server that is available and capable of fulfilling the request. This prevents any one server from becoming a bottleneck, which can lead to slow performance or complete service failure.

There are various algorithms used for kuormitusjakelu, such as round-robin, least connections, and weighted methods. Round-robin distributes requests sequentially to each server. Least connections sends requests to the server with the fewest active connections. Weighted methods assign different capacities or priorities to servers.

Kuormitusjakelu is a crucial component for ensuring high availability and reliability of applications and services, especially in environments with high traffic volumes. It can be implemented at different layers of the network stack, from the transport layer to the application layer. By distributing the workload, kuormitusjakelu enhances the overall performance and stability of a system.
