What is the difference between horizontal and vertical scaling?
Linux extends applications and database capability with platform coverage and scalability. Horizontal and vertical scaling meet business processing demands across multiple platforms and computing architectures. Scalability is a key success factor for business applications in a dynamic environment. Platform scalability is expressed in the number of processors driven by one operating system (2-way, 4-way, 8-way and so on). The growth of processors within one operating environment is called vertical scaling. Horizontal scaling is leveraging multiple systems to work together on a common problem in parallel. Each system has its own operating system and one or more processors controlled by each system image.
