ETX (Enterprise Technology Exchange) — Dependency for LSF, VPN Required

ETX is a prerequisite for LSF (Load Sharing Facility) and requires a site-to-site VPN to be operational before it can function. Dependency Chain: VPN → ETX → LSF

Resource Requirements

• VPN gateway or AWS Site-to-Site VPN connections in each relevant region
• Sufficient bandwidth on the VPN for ETX communication overhead
• Network ACLs and security groups configured to permit ETX traffic flows
• ETX services configured over the VPN tunnel
• LSF then leverages ETX for job scheduling and resource management

Professional Services Core Skillsets

• Cloud Network Architecture — Design and implementation of AWS Site-to-Site VPN, VPC peering, Transit Gateway, routing tables, and firewall/NACL rules
• Enterprise Integration / Middleware — ETX installation, configuration, and integration over VPN tunnels; ensuring reliable message exchange between on-premises and cloud environments
• HPC / Batch Computing — IBM Spectrum LSF deployment, cluster configuration, job scheduling policies, and integration with ETX for workload orchestration
• Security & Compliance — IAM policies, encryption in transit (IPSec), network segmentation, and audit logging across VPN and ETX layers
• Infrastructure Automation (IaC) — CloudFormation / Terraform for repeatable VPN and networking provisioning across multi-region deployments
