scale up
InIT engineering, scale-up is the upgrading ofcomputers, servers or other system components for the purpose of increasing performance.
Servers are Symmetric Multiprocessing( SMP) server system architectures that share very large main memories and powerful peripherals. In general, these are systems that feature scalability and flexibility and are used for data-intensive computations. Depending on the application and infrastructure, a scale-up or a scale-out can be the optimal solution approach.
