Skaalitavusest, 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. It is a critical aspect of system design and architecture, particularly in the context of software development and IT infrastructure. Scalability can be categorized into two main types: vertical scalability and horizontal scalability.

Vertical scalability, or scale-up, involves increasing the capacity of a single system by adding more resources such as CPU, memory, or storage. This approach is often used in traditional computing environments and can be limited by the physical constraints of the hardware. Horizontal scalability, or scale-out, involves adding more machines or nodes to a system to distribute the workload. This approach is more flexible and is commonly used in modern distributed systems and cloud computing environments.

Scalability is influenced by various factors, including the architecture of the system, the nature of the workload, and the underlying technology. For example, systems that are designed with microservices architecture tend to be more scalable than monolithic systems. Similarly, systems that are designed to handle stateless requests can be more easily scaled horizontally than those that require stateful interactions.

Measuring scalability involves evaluating the system's performance under increasing loads and determining the point at which performance degrades significantly. This can be done through various methods, including load testing, stress testing, and capacity planning. Scalability is a crucial consideration in the design and implementation of any system, as it directly impacts the system's ability to meet the demands of its users and the overall user experience.
