Securing HPC on AWS – isolated clusters
HPC Blog
This article discusses ways to run isolated HPC clusters on AWS using AWS ParallelCluster, where the clusters have no inbound or outbound internet connectivity. It covers two solutions - one with Active Directory (AD) integration and one without.
Specifically, the article covers:
- Background on why certain industries require network isolation for HPC workloads on AWS
- High-level architecture for isolated HPC clusters on AWS
- How to establish connectivity to AWS services from an isolated subnet using VPC endpoints
- Required VPC endpoints for common ParallelCluster functions
- Considerations for shared storage options like FSx, EFS, and EBS in isolated subnets
- Configuration changes needed for isolated ParallelCluster deployments
- Differences between the isolated cluster solution with and without AD integration
- Conclusion highlighting the flexibility and scalability of these solutions
