Transparent Deployment of Scientific Workflows across Clouds - Kubernetes Approach

We present an end-to-end solution for automation of scientific workflow deployment and execution on distributed computing infrastructures. The solution integrates de-facto standard and widely adopted tools, including Terraform and Kubernetes, with our HyperFlow workflow management system. In such a solution, infrastructure providers have abstracted away thanks to generic Kubernetes layer. However, we also support other computing infrastructures, both containerized such as Kubernetes or Amazon ECS, and non-containerized, e.g. Amazon Lambda, in a single unified approach. The resulting solution enables execution of hybrid workflows that utilize multiple computing infrastructures and significantly lowers the complexity related to management of repeatable infrastructures for the execution of scientific workflows and conducting scientific workflow research.
