LVSArchitektur

LVSArchitektur is a design philosophy and approach to building scalable and highly available network services. It emphasizes the use of Load Balancing Virtual Servers (LVS) to distribute incoming network traffic across multiple backend servers. This distribution ensures that no single server becomes overloaded and that the overall service remains accessible even if individual servers fail.

The core principle of LVSArchitektur involves a dedicated LVS router that acts as a single point of access for clients. This router intercepts all incoming requests and intelligently forwards them to one of the available real servers based on a chosen load balancing algorithm. Common algorithms include round-robin, weighted round-robin, least-connection, and IP hash.

By abstracting the backend servers behind a virtual IP address, LVSArchitektur provides a transparent layer of fault tolerance and scalability. Clients are unaware of the individual servers behind the LVS, simplifying client configuration and management. When a real server goes offline, the LVS automatically detects the failure and stops sending traffic to it, redirecting it to the remaining healthy servers. This ensures continuous service availability.

The scalability aspect is achieved by simply adding more real servers to the pool. As demand increases, additional servers can be provisioned and registered with the LVS, allowing the system to handle a larger volume of traffic without performance degradation. This makes LVSArchitektur a popular choice for high-traffic web applications, databases, and other network-intensive services.
