Description: Scalability is the ability of a system to handle an increasing amount of work or its potential to accommodate growth. This concept is fundamental in the design of computer systems, web applications, and software architectures, as it allows organizations to adapt to the variable demand for resources. Scalability can be vertical, where more resources are added to a single node (such as increasing the memory or processing capacity of a server), or horizontal, where more nodes are added to the system (such as adding more servers or resources to a network). The importance of scalability lies in its ability to ensure that a system can continue to operate efficiently as the workload increases, which is crucial for maintaining optimal performance and a good user experience. In the context of distributed systems, scalability is essential for handling a large number of simultaneous requests, while in agile methodologies, it relates to a team’s ability to adapt and grow in response to changes in project requirements or market demand.
