Even with high CPU loads, due to license costs for expensive proprietary software, the advantage can shift towards mainframes when dedicated Application Assist Processors (zAAP) are employed, because usually only the generic CPUs have to be licensed. By offloading work to the &#x27;license-free&#x27; zAAPs, overall throughput can be greatly increased with equal license costs.<p>Of course, this scenario isn&#x27;t what LinuxONE boxes are made for; they are more focused towards open source deployments in the enterprise, with low license costs (usually only support contract costs).
