Scale-out Computing

Scale-out computing refers to expanding a system's capacity by adding more individual units, like servers or computers, rather than upgrading existing ones. This approach allows handling increased workloads efficiently by distributing tasks across multiple machines. It's similar to adding more lanes to a highway to accommodate more traffic—performance improves as you add more units. Scale-out is common in data centers and cloud services, enabling flexible, cost-effective growth for applications and data processing without overloading a single machine.
