   A university runs a research application on-premises that requires high-performance computing (HPC) for a few weeks each year. The rest of the year, the application is used lightly. The university wants to reduce the cost of maintaining idle HPC hardware. Which approach is most cost-effective while keeping the application available year-round?

   • AKeep the full HPC cluster on-premises and run it year-round.
   • BBuild a second on-premises HPC cluster to share the load.
   • CUse a hybrid approach: keep a minimal on-premises HPC cluster for light usage and burst to Azure HPC resources during the peak research period.
   • DMigrate the entire HPC application to Azure and run it year-round.
