AWS  Cloud Solutions Architect - (VPN → ETX → LSF) - REMOTE

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
  

• 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
  

EVS (Elastic VMware Service)

EVS provides VMware Cloud Foundation on AWS, enabling lift-and-shift of VMware-based workloads to AWS without re-platforming.
Resource Requirements:

• EVS cluster provisioning in target AWS regions
  
• vCenter, ESXi host, and vSAN configuration within the EVS environment
  
• Network connectivity between EVS and native AWS services (VPC integration, ENI attachments)
  
• VM migration tooling (HCX or equivalent) for workload mobility from on-premises VMware to EVS
  
• Licensing alignment for VMware components
  

Professional Services Core Skillsets:

• VMware Administration / vSphere Engineering — vCenter management, ESXi host configuration, vSAN storage policies, VM lifecycle management, and DRS/HA cluster tuning
  
• AWS EVS / VMware Cloud Specialization — EVS cluster deployment, SDDC configuration, integration with AWS native services (S3, EBS, VPC), and hybrid connectivity design
  
• Migration & Workload Mobility — VMware HCX deployment and configuration, bulk VM migration planning, cutover orchestration, and rollback procedures
  
• Cloud Network Architecture — EVS networking (NSX or VPC-based), connectivity to native AWS VPCs, DNS integration, and cross-region traffic routing
  
• Security & Identity — vCenter RBAC, integration with AWS IAM, NSX micro-segmentation, and compliance controls for VMware workloads on AWS
  
• Infrastructure Automation (IaC) — Automated provisioning of EVS environments using Terraform, CloudFormation, or VMware Aria Automation
  

Professional Services Core Skillsets:

• NetApp / ONTAP Storage Engineering — FSx for ONTAP provisioning, volume and SVM management, snapshot policies, tiering policies, ONTAP CLI/REST API operations, and performance tuning
  
• AWS Storage Architecture — FSx for ONTAP sizing and deployment, throughput capacity planning, integration with VPCs, and cost optimization (capacity pool vs. SSD tier)
  
• Data Migration & Replication — SnapMirror configuration for cross-region replication, NetApp XCP or robocopy for bulk data migration, cutover planning, and data validation
  
• Cloud Network Architecture — VPC subnet design, security groups for NFS/SMB/iSCSI protocols, cross-region VPC peering for replication traffic, and DNS configuration for file system endpoints
  
• Linux / Windows Systems Engineering — NFS mount configuration on Linux, SMB share mapping on Windows, multi-protocol access testing, and client-side performance tuning
  
• Backup, DR & Data Protection — AWS Backup integration with FSx for ONTAP, snapshot scheduling, cross-region DR strategy, and RTO/RPO validation
  
• Security & Compliance — Encryption at rest (KMS), encryption in transit, IAM policies for FSx access, ONTAP export policies, and data governan
