isäntäperusteiset

isäntäperusteiset refers to a concept in Finnish, often translated as "host-based" or "landlord-based" in English, particularly in contexts related to software, systems, or services. It describes a model where the primary functionality, processing, or data storage resides on a central server or host machine, rather than being distributed across individual client machines or devices.

In a software context, isäntäperusteiset applications might require a powerful server to handle all the computational tasks. Clients, often referred to as "terminals" or "thin clients," primarily serve as interfaces for users to interact with the application running on the host. This approach simplifies software management, as updates and maintenance are performed on the central server. It can also lead to more consistent user experiences across different client devices.

The term can also be applied to network infrastructure or service provisioning. For example, an isäntäperusteinen network security model would rely on a central firewall or intrusion detection system on the network's edge to protect all connected devices. Similarly, in some older computing models, a mainframe computer acted as the isäntä, serving multiple terminals. This contrasts with client-server architectures where both client and server have significant processing capabilities, or peer-to-peer networks where responsibilities are distributed among many nodes. The effectiveness of an isäntäperusteinen system often depends on the reliability and capacity of the central host.
