Cloud bursting in Slurm is a feature that allows a Slurm cluster to expand its computing resources into a cloud environment, meeting increased demand for computing resources. When the on-premises resources of a Slurm cluster are insufficient, bursting allows the cluster to temporarily extend its capacity by utilizing cloud resources. This can help organizations manage peak workloads without having to invest in and maintain additional physical hardware
Slurm can be configured to work with various cloud providers such as Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform (GCP), and more. It uses cloud APIs to create and manage virtual machines (VMs) in the cloud.
