Why HPC on Cloud?

n Quick Scalingn Focus on Software to increase productivityn Flexible Architecturen Utility Costing Modeln Easy integration with other Cloud services

Recommendations to secure HPC on Cloud

n Don’t open to publicn Use 2-factor based VPN if publicn Limit outgoing access

n Simplicity is Safetyn Don’t overly complicate your stack

n Automate your stack (build whole stack everytime)n Don’t rely on configuration management

n Make data not valuable (eg. use Data Masking)
