Many architectures apply to both loosely coupled and tightly coupled workloads and may require slight modifications based on the scenario. Traditional, on-premises clusters force a one-size-fits-all approach to the cluster infrastructure. However, the cloud offers a wide range of possibilities and allows for optimization of performance and cost. In the cloud, your configuration can range from a traditional cluster experience with a scheduler and login node to a cloud-native architecture with the advantages of cost efficiencies obtainable with cloud-native solutions. Five reference architectures are below.
