StackHPC is one of the leading OpenStack consultancies working with research institutions worldwide. Formed in 2016 StackHPC has established a formidable reputation with eminent organisations developing OpenStack for their benefit and enabling OpenStack client teams to support their mission critical operations. Our focus is on the Research or Scientific Computing landscape where the demands of high performance computing can place exacting requirements on the underlying configuration, especially when dealing with the software-defined complexities of modern on-premise cloud infrastructure, together with extending this model to hybrid cloud environments. While Research Computing remains our focus, we also support clients across the industrial, retail and financial sectors who share a similar mission in performance. StackHPC has many clients for which we have installed and support a Kolla-Ansible based OpenStack deployment; StackHPC currently employs the both current and former Kolla-Ansible Project Technology Lead within the Open Infrastructure Foundation. These deployments are set in a HPC virtualised and/or bare metal environment and deploy predominantly Slurm and Kubernetes platforms either as managed or self-service configuration options using Terraform and Ansible. In addition to ostensibly OpenStack consultancy StackHPC, also works with clients within public cloud settings. All software is maintained as open source within CI/CD git repositories. StackHPC’s engagement model is founded on the following principles: Focus on research computing - realising and sustaining high performance Design and requirements capture to explore commonalities of approach Reduce complexity and operational burden Training, monitoring, testing and support Continuous knowledge transfer
