ARM architectures represent a different approach to how the hardware for a system is designed when compared to more familiar server architectures like x86. The ARM ecosystem has emerged over the last several years with server optimized products and solutions that are designed for cloud and hyperscale computing, telecommunications, and edge computing, as well as high-performance computing (HPC) applications.
