IntroductionThe Acorn RISC Machine, or ARM as it is now known, and later processor architecture has become a cornerstone in the landscape of Information Technology (IT) and modern computing. Initially designed for Acorn Computers in the 1980s, ARM processors have evolved to become the driving force behind a multitude of devices, ranging from smartphones and tablets to embedded systems and servers. One of the key reasons for the widespread adoption of ARM architecture is its Reduced Instruction Set Computing (RISC) design philosophy, which emphasizes simplicity and efficiency in instruction execution. This design choice makes ARM processors highly energy-efficient, making them ideal for portable devices where battery life is a critical factor.
Crafting an ARM architecture container imageBuilding containers for ARM architecture can pose challenges, primarily due to the prevalence of Intel and AMD architectures in the majority of computing environments. Several factors contribute to the complexities associated with developing software for ARM when the industry standard is predominantly (at the time of writing this blog post) Intel/AMD based.
