Cornerstone Technical Solutions
Services · Red Hat Partner · SDVOSB

From VMware exit to 3am pager. One senior team.

We migrate, build, and operate OpenShift and Kubernetes platforms for regulated, mission-critical, and edge environments — then govern how AI ships to them. Senior engineers only. No offshore hand-offs.

How our services fit together

One team, from first assessment to day-two operations.

Start wherever you are. Every service hands off cleanly to the next — usually to the same engineers.

Most migrations and builds transition into managed operations — the engineers who built it stay on to run it.
01
Migration · Flagship

Migrate off VMware — or shrink it. Keep your VMs either way.

Broadcom changed the economics of VMware overnight. Move your whole estate, or run OpenShift Virtualization alongside vSphere and cut what you license. Either way, we move your virtual machines onto Red Hat OpenShift Virtualization with the Migration Toolkit for Virtualization — cold and warm migrations, network and storage mapping, and wave-based cutovers that keep workloads running. Done in production on bare metal with enterprise storage, including CJIS-scoped government environments.

  • ✓Readiness assessment: inventory, dependency mapping, sizing, and a migrate-or-rebalance plan
  • ✓Pilot migration proves the full path before production moves
  • ✓Wave-based migration with MTV/Forklift, plus guest remediation (virtio, guest agent, boot fixes)
  • ✓Software-defined storage and modern data protection built in, not bolted on
  • ✓VMs and containers side by side — one platform, one operating model

Managed operations · 24×7

Your platform, run by the people who'd build it.

We operate OpenShift and Kubernetes as a true extension of your team — the senior engineers who run your changes are the ones who answer your 3am P1. Today we run a 30+ cluster shipboard fleet plus shoreside clusters for a Fortune-500 enterprise.

  • ✓24×7 coverage from named, US-based senior engineers — no shared NOC
  • ✓Tiered SLAs with acknowledge, engage, and mitigate milestones
  • ✓Upgrades, patching, scaling, backup/DR operations, and incident response
  • ✓Clean Red Hat escalation when an issue is upstream
  • ✓Transparent per-cluster pricing — no surprise change orders

Federal & disconnected

OpenShift where the internet doesn't reach.

Most integrators can deploy OpenShift. Far fewer can deploy it fully disconnected, hardened to federal standards, in a classified facility. Our background spans USMC, DoD, FBI, and DHS engagements — and as an SDVOSB we bring the contracting access government work requires.

  • ✓Air-gapped installs: Quay mirror registry, oc-mirror pipelines, agent-based deployment
  • ✓DISA STIG hardening via the Compliance Operator, FIPS mode, continuous compliance
  • ✓FedRAMP and DoD Impact Level readiness
  • ✓Authorized supply chain: Red Hat Satellite, Iron Bank / Platform One
  • ✓Cross-domain and media-transfer workflows for true air gaps

Edge & fleet

Run containers where the network barely reaches.

Disconnected sites, intermittent links, hundreds of identical locations — that's where most platform teams struggle and where we're strongest. We design and operate containerized edge fleets with Podman, Quadlet, and pull-based GitOps, so every site stays consistent, self-heals, and updates safely. Built for maritime, retail, manufacturing, and any estate of remote sites.

  • ✓Fleet architecture that survives intermittent and low-bandwidth links
  • ✓Pull-based GitOps and image-mode delivery for atomic, rollback-safe updates
  • ✓Consistent configuration and security posture across every site
  • ✓Edge-appropriate WAF and end-to-end TLS — no heavyweight control plane
  • ✓Centralized fleet management without per-site cluster sprawl

Platform builds05

Bare-metal OpenShift & Virtualization builds

Production OpenShift on your hardware — where the hard problems actually live.

  • ›Agent-based, IPI, or UPI cluster deployment
  • ›Portworx, Pure FlashArray, or ODF storage — RWX for live-migratable VMs
  • ›VLAN/OVN, EgressIP, MetalLB, and NIC bonding
  • ›Day-two runbooks tailored to your environment

Woven through everything we do

Controls as engineering guarantees, not policy documents.

Separation of duties enforced as a technical control. Audit evidence generated automatically. Compliance encoded as policy-as-code instead of a binder nobody maintains — delivered for SOX-scoped financial systems and CJIS-scoped government environments.

Why Cornerstone

Production-proven, not PowerPoint-proven.

We've done the hard version.

Bare-metal OpenShift Virtualization migrations with enterprise storage, complex networking, and full day-two operations — in production, under real constraints.

Veteran-owned, federal-ready.

A background spanning USMC, DoD, FBI, and DHS. SDVOSB and NVBDC certified. Red Hat Partner. The access and depth government work requires.

Senior engineers, not hand-offs.

You work directly with the people who do the work — 24 years of DevOps, automation, cloud, storage, and container experience behind every engagement.

Our platform · a product, not a service

Governing what AI ships to production.

TruStacks is our AI delivery-governance platform: agents propose, policy decides, humans approve. Every change is checked against signed policy-as-code before a human reviews it — no autonomous path to production, by design.

TruStacks — Let AI handle delivery. Without giving up control.
Git push. Go home.
