Skaalaavuus

Skaalaavuus, also known as scalability, refers to the ability 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 the capability of a system to increase its total throughput under an increased load when resources (typically hardware) are added. This can be achieved through vertical scaling, which involves adding more power (CPU, RAM) to an existing machine, or horizontal scaling, which involves adding more machines to the system.

Scalability is a critical factor in the design and implementation of systems, particularly in cloud computing, where resources can be dynamically allocated based on demand. It is often measured in terms of performance metrics such as response time, throughput, and resource utilization. A scalable system is designed to maintain or improve performance as the workload increases, ensuring that it can handle growth without significant degradation in service quality.

There are different types of scalability, including:

- Elasticity: The ability to automatically adjust resources in response to demand.

- Fault tolerance: The ability to continue operating properly in the event of the failure of some of its components.

- Load balancing: The ability to distribute workloads across multiple computing resources to ensure no single resource becomes a bottleneck.

Scalability is influenced by various factors, including the architecture of the system, the efficiency of the algorithms used, and the underlying hardware. Achieving scalability often requires a combination of good design principles, efficient coding practices, and the use of appropriate technologies and tools.
