THE PERILS OF BECOMING TRAPPED IN THE CLOUD
Terms like ‘open systems’ have been bandied about for decades. While modern computer systems are relatively open compared to their predecessors, there are still plenty of opportunities to become locked into proprietary interfaces. In this article, we explore the challenge of proprietary lock-in in the age of cloud-based HPC and recommend strategies to help you stay portable and flexible. In the early 1990s lock-in at the level of hardware and operating systems was a major concern. Frustrated with costly proprietary systems, customers began looking towards UNIX as a preferred platform. While not widely used for commercial applications at the time, it was perceived as open. There were only a few dialects, and implementations were mostly standard among vendors. The IEEE’s Portable Operating System Interface standards (POSIX 1003.x) began appearing in RFPs, and although there continued to be multiple processor architectures, the push-pull of innovation and customer demand helped impose more uniformity across operating systems and file systems.
