Võrgusuhtlust

Võrgusuhtlust, also known as network balancing or load balancing in English, refers to the process of distributing incoming network traffic across multiple servers to optimize resource use, maximize throughput, minimize response time, and avoid overload on any single server. This technique is widely used in modern computing environments, particularly in web hosting, cloud computing, and distributed systems.

The primary goal of võrgusuhtlust is to ensure high availability and reliability of services. By evenly distributing the workload, it prevents any single server from becoming a bottleneck, thereby improving overall system performance and resilience. Load balancers, which are specialized devices or software applications, play a crucial role in this process. They act as intermediaries between clients and servers, directing requests to the most suitable server based on predefined algorithms.

Common algorithms used in võrgusuhtlust include round-robin, least connections, IP hash, and weighted distribution. Round-robin distributes requests sequentially among servers, while least connections directs traffic to the server with the fewest active connections. IP hash ensures that requests from the same client are consistently routed to the same server, which is useful for maintaining session persistence. Weighted distribution allows administrators to assign different weights to servers based on their capacity or performance, ensuring that more capable servers handle a larger share of the load.

Võrgusuhtlust is essential for scaling applications horizontally, allowing businesses to handle increased traffic without investing in additional hardware. It also enhances fault tolerance by rerouting traffic away from failed servers, ensuring continuous service availability. Additionally, load balancing can improve security by distributing attacks across multiple servers, reducing the impact of denial-of-service (DoS) attacks. Overall, võrgusuhtlust is a fundamental component of modern infrastructure, enabling efficient and reliable service delivery.
