Scalability
Plain English
Handling more users without breaking.
Definition
Scalability is the ability of a glossarySystemA system is a collection of interconnected components that work together to achieve a specific function or outcome.Open glossary term to handle increased demand without losing glossaryPerformancePerformance refers to how quickly and efficiently a system responds to user actions and processes tasks.Open glossary term.
In practice
Achieved through glossaryArchitectureArchitecture refers to the structure and organisation of a system, including how components interact and are designed.Open glossary term design, glossaryCloudCloud refers to the delivery of computing services such as storage, processing, and networking over the internet.Open glossary term glossaryInfrastructureInfrastructure refers to the underlying systems and resources that support applications and services.Open glossary term, and optimisation.
In context
It is worth distinguishing from current capacity. A glossarySystemA system is a collection of interconnected components that work together to achieve a specific function or outcome.Open glossary term handling today's load comfortably may still be unscalable if the only way to grow it is to buy a bigger machine.
The reality
Many glossarySystemA system is a collection of interconnected components that work together to achieve a specific function or outcome.Open glossary term are not built to scale and struggle as usage grows.
Compared with
Scalability vs Performance
glossaryPerformancePerformance refers to how quickly and efficiently a system responds to user actions and processes tasks.Open glossary term is how fast the glossarySystemA system is a collection of interconnected components that work together to achieve a specific function or outcome.Open glossary term is now. Scalability is whether it stays that fast as load grows. A fast system with a hard ceiling and a slower one that scales linearly fail in very different ways.
