Scalability solutions refer to strategies and technologies that enable a system to handle increased loads or demands without compromising performance. These solutions can be applied to various areas, including software applications, databases, and network infrastructure. By implementing scalability solutions, organizations can ensure that their systems grow efficiently as user numbers or data volumes increase. There are two main types of scalability: vertical and horizontal. Vertical scalability involves adding resources, such as CPU or memory, to a single server, while horizontal scalability involves adding more servers to distribute the load. Both approaches can be tailored to meet the specific needs of a business, ensuring optimal performance as it expands.
