Nutanix Cloud Clusters (NC2) on AWS: A Hybrid Workflow for Operational Symmetry
Patch your IAM policy to create a dedicated User‑Nutanix‑NC2 with least privilege, open an AWS Support Case for dedicated host quota, and manually launch an EC2 instance to verify availability before deploying NC2.

Summary
Nutanix Cloud Clusters (NC2) on AWS offers a hybrid workflow that treats AWS as a native cluster through Prism, addressing the hybrid paradox where organizations want AWS elasticity but stay tied to on‑prem VMware, vCenter or Hyper‑V. The author emphasizes operational symmetry over simple lift‑and‑shift, recommending a pre‑flight assessment with Nutanix Move or RVTools to capture RAM, vCPU, and disk density rather than just totals. Before touching the AWS console, you must open an AWS Support Case to request a quota increase for dedicated host families such as i3 or i4i metal, a process that can take at least a week. After approval, launching a single EC2 instance of the requested type manually verifies host availability before the NC2 deployment.
Security best practices involve creating a dedicated IAM user (e.g., User‑Nutanix‑NC2) with a third‑party policy scoped to the Nutanix Manager, applying least privilege. Connectivity is achieved via an AWS Site‑to‑Site VPN and manual adjustments to VPC route tables to point the on‑prem CIDR to the Virtual Private Gateway. The ROI comes from standardizing operations across failure domains, enabling a disaster‑recovery plan with lower RTOs and a single pane of glass. Resources for implementation include the NC2 listing on AWS Marketplace, the Nutanix Test Drive guide, and the Nutanix University certification path.
