Which architecture is described as having a server that does everything, with high costs to upgrade?

• A. Client based architecture
• B. Host based architecture
• C. Cloud-based architecture
• D. Peer-to-peer architecture

Answer: (B)

Centralization is being tested here: all processing and services are handled by a single central server, with clients mostly acting as interfaces. In a host-based architecture, that one server does the work, so everything hinges on that central host. Upgrading it tends to be expensive because capacity, performance, and features are added by beefing up or replacing that central server and its software stack, often with downtime and licensing considerations. The system becomes more prone to bottlenecks and a single point of failure since the whole operation depends on that one host. By comparison, other setups distribute work differently. A client-based approach pushes processing to the end-user devices, reducing central upgrade costs but increasing the burden on clients. Cloud-based architectures leverage elastic resources in the cloud, making upgrades more about adjusting usage and services rather than hard hardware upgrades. Peer-to-peer spreads processing across many nodes, removing the need to upgrade a single server. But when you hear about a server that does everything with high upgrade costs, the description clearly aligns with a host-based architecture.
