How does Scale-Out Architecture expand its capacity?

Scale-Out Architecture expands its capacity primarily by adding more nodes to a system. This approach allows for the distribution of data and workloads across multiple machines, which enhances performance and storage capabilities. As additional nodes are integrated into the architecture, they work collaboratively, thereby increasing the overall capacity and scalability of the system without the limitations that might come from upgrading or resizing existing nodes.

This method is particularly advantageous in environments where data growth is dynamic and unpredictable, as it enables organizations to scale horizontally. Each new node can operate independently but still be part of a larger cohesive system, allowing for more efficient resource utilization and improved fault tolerance. This design contrasts with other approaches that might involve enhancing the capabilities of current nodes or redistributing workloads, which may not provide the same level of scalability or efficiency in accommodating growth.
