Accelerating automation of digital health applications via cloud native approach

View publication


Writing thread safe code for concurrent processing requires experience and training, thus legacy research code are usually single threaded, which post a challenge when it comes to scaling. This challenge is harder to overcome in the digital health domain, where code changes might trigger a regulatory review process. In this work, we report a solution of leveraging container technology to convert single threaded legacy code into cloud native services, scaling out data processing throughput via data parallelism. We tested the setup with a batch data processing job on the EverythingALS dataset and obtained 8X speed up compared to single threaded processing. This solution is built as part of IBM Health Guardian, a digital health tool suite. It is generalizable and can be adapted to other projects. The work greatly improves the automation of adoption of legacy research code in the evolving digital health domain. It will attract more open domain research contributions.
