Scalability refers to a system’s ability to handle increased loads or demands effectively without compromising performance or functionality.
Key Aspects:
- Can be vertical (adding resources to existing nodes) or horizontal (adding more nodes).
- Important for applications that experience variable workloads or growth over time.
- Allows organisations to adapt resources based on demand fluctuations.
Benefits:
- Supports business growth without requiring complete system overhauls.
- Enhances system reliability and performance under heavy loads.
- Reduces costs by optimising resource use during peak times.
Scalability is crucial for cloud computing services, web applications and large databases where demand can vary significantly over time.
