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
