Why architecture determines system scalability in SCADA systems - Quick Recap

Recall & Review

beginner

What is system scalability in the context of SCADA systems?

System scalability is the ability of a SCADA system to handle increased workload or expand its capacity without performance loss.

beginner

How does system architecture affect scalability?

Architecture defines how components connect and communicate, which impacts how easily the system can grow or handle more data and users.

intermediate

What is a monolithic architecture and its impact on scalability?

A monolithic architecture combines all functions in one unit, making it harder to scale parts independently and often limiting system growth.

intermediate

Why are modular or distributed architectures better for scalability?

They separate functions into parts that can be scaled independently, allowing the system to grow smoothly and handle more load.

beginner

Give an example of how poor architecture limits SCADA system scalability.

If all sensors send data to one central server without load balancing, the server can become overwhelmed, causing slowdowns or failures.

What does scalability mean in a SCADA system?

A Ability to handle more workload without performance loss

B Ability to reduce system size

C Ability to change hardware only

D Ability to work offline

Scalability means the system can grow or handle more work smoothly.

Which architecture type usually limits scalability the most?

A Distributed architecture

B Modular architecture

C Monolithic architecture

D Cloud architecture

Monolithic architecture bundles everything together, making scaling difficult.

Why is modular architecture good for scalability?

A Because it avoids network communication

B Because it combines all functions in one unit

C Because it uses less hardware

D Because it allows independent scaling of parts

Modular design lets you grow parts separately, improving scalability.

What happens if a SCADA system has poor architecture when workload increases?

A System performance improves

B System slows down or fails

C System automatically upgrades hardware

D System ignores extra workload

Poor architecture can cause slowdowns or failures under heavy load.

Which factor is NOT directly related to system scalability?

A User interface color scheme

B Component communication

C Architecture design

D Load balancing

User interface colors do not affect scalability.

Explain why system architecture is crucial for SCADA system scalability.

Think about how parts of the system work together and grow.

Describe the difference between monolithic and modular architectures in terms of scalability.

Consider how easy it is to grow or change parts.
