skaloituvuudessa

Scalability refers to the capability of a system, network, or process to handle a growing amount of work, or its potential to be enlarged to accommodate that growth. In computing, scalability is a key characteristic of systems designed to support a large number of users or a large volume of operations. A system is considered scalable if it can maintain or improve its performance as demand increases. This can be achieved through various means, such as adding more hardware resources (vertical scaling) or adding more instances of existing resources (horizontal scaling).

In the context of software development, scalability often relates to how well an application can handle increased load. This might involve optimizing code, using efficient data structures, or designing the architecture to distribute workloads. For instance, a web application that can serve more users by simply adding more servers to a load balancer is considered horizontally scalable. Conversely, a system that can handle more load by upgrading its existing server to a more powerful one is exhibiting vertical scalability.

The concept extends beyond computing. In business, scalability refers to a company's ability to grow its revenue without a proportional increase in costs. This implies an efficient operational model that can expand to meet higher demand. Similarly, in economics, a scalable industry is one where output can increase significantly without a corresponding rise in marginal costs. Understanding and achieving scalability is crucial for the long-term success and sustainability of many systems, businesses, and processes.
