Scalable systems refer to systems that are designed to handle a growing amount of work or its potential to accommodate growth. In the context of research, scalable systems typically involve the development, modeling, and implementation of systems that can efficiently and effectively handle increasing amounts of data, users, or workload. This may include the use of distributed systems, parallel computing, load balancing, and other techniques to ensure that the system can continue to perform effectively as it scales up in size or complexity. The goal of scalable systems research is to enable organizations to build flexible and adaptable systems that can grow and evolve along with their needs and demands.
