Infrastructure as Code (IaC) enables efficient deployment and operation, which are crucial to releasing software quickly. As setups can be complex, developers implement IaC programs in general-purpose programming languages like TypeScript and Python, using PL-IaC solutions like Pulumi and AWS CDK. The reliability of such IaC programs is even more r...

DevOps encourages independent, cross-functional teams to improve the Software Delivery and Operational (SDO) performance. Despite independence being a primary goal software applications managed by different teams often depend on each other in practice. These dependencies impact the deployment, requiring teams to coordinate to ensure the correct ope...

The advent of cloud computing has enabled large-scale availability of on-demand computing and storage resources. However, these benefits are not yet at the fingertips of HPC developers: Typical HPC applications use on-premise computing resources and rely on static deployment setups, reliable hardware , and rather homogeneous resources. This hinders...

High Performance Computing (HPC) is crucial in a number of sectors, including weather forecasts, particle simulations and fluid dynamics. Existing programming frameworks for HPC expose developers to low-level details such as message passing and explicit memory management, which are hard to program and error-prone. In this paper, we present ongoing...

Distributed query processing is an effective means for processing large amounts of data. To abstract from the technicalities of distributed systems, algorithms for operator placement automatically distribute sequential data queries over the available processing units. However, current algorithms for operator placement focus on performance and ignor...
