Centralised vs. Distributed Control Systems

Centralised Control Systems

Centralised control systems rely on a single central computer to manage all processing and decision-making.

Definition

Centralised control system

A control system that relies on a single central computer to manage all processing and decision-making

This architecture offers several advantages:

Simplified Management: All data and processes are handled in one location, making it easier to monitor and control.
Cost-Effective: Client devices require minimal hardware since the central system performs all computations.
Enhanced Security: Data is stored centrally, reducing the risk of unauthorised access across multiple locations.
Efficient Backup: With all resources in one place, backing up data is straightforward and less resource-intensive.

Note

Centralised systems are often used in environments where reliability and control are paramount, such as banking systems or large-scale enterprise networks.

In contrast, the disadvantages are:

Single Point of Failure: If the central system or its connection fails, the entire network can become inoperative.
Scalability Challenges: Expanding the system requires a significant investment in the central infrastructure.
