What is the primary feature of Scale-Up Architecture?

The primary feature of Scale-Up Architecture is that it increases capacity by adding resources to a single node. This approach focuses on enhancing the capabilities of an existing server or storage unit by upgrading components such as CPU, memory, or storage within that node. This method allows for significant improvements in performance and efficiency without the complexity of managing multiple nodes, which often accompanies Scale-Out Architecture.

This architecture is particularly beneficial in environments where high performance is required for applications that need to handle large amounts of data or perform intensive computations. By concentrating resources within a single node, it simplifies management and can often lead to better resource utilization since all upgrades and expansions occur in one place. The benefits include easier scalability and a reduction in the overhead associated with network communication that can arise when using multiple nodes.
