In the IT world, scalability refers to the ability of a system, infrastructure or application to adapt flexibly to increasing requirements.
This is achieved by increasing resources, performance and capacity accordingly. Resources include, for example, computing power, memory, bandwidth or user access. This adaptation has no negative impact on stability, efficiency, functionality or performance.
Scalability allows systems to grow with increasing load and provide a seamless and reliable experience for users. Especially in cloud computing environments and web applications, scalability can help meet ever-changing requirements and ensure smooth operations.
