Understanding Scalability and Architecture

What is scalability?

• Ability to reduce workload

• Ability to handle growth in workload while maintaining performance

• Reducing cost of operations

• Enhancing user interface

Why is scalability important?

• Increases system complexity

• Increases hardware usage

• Ensures system flexibility and cost efficiency

• Enhances software design aesthetics

What does “designing for scalability” refer to?

• Creating small applications for testing

• Developing systems that handle increasing workloads without performance loss

• Designing for minimal hardware usage

• Building applications with low user engagement

Which of the following is a type of scalability design?

• Local scaling

• Vertical scaling

• Top-down scaling

• Bottom-up scaling

Vertical scaling refers to:

• Adding more servers to distribute the load

• Decreasing system resource usage

• Increasing capacity of a single server

• Reducing system reliability

Horizontal scaling involves:

• Using a single high-capacity server

• Adding multiple servers to handle workload

• Reducing the number of user requests

• Minimizing server response times

One advantage of vertical scaling is:

• Low cost

• Increased complexity

• Consistency

• High network latency

A disadvantage of vertical scaling is:

• Increased flexibility

• Limited upgrade capacity

• Enhanced performance

• Reduced redundancy

Which is an advantage of horizontal scaling?

• Simplicity

• Cost-effectiveness

• Increased single-point failure risk

• Inconsistent performance

A disadvantage of horizontal scaling is:

• Increased consistency

• Higher redundancy

• Complexity in management

• Reduced performance
