🏠 Private Cloud Server

Elastic On-Prem & Colo — Secure-by-Default, Cost-Smart, and Proven Daily

Private Cloud gives you public-cloud speed with on-prem/colo sovereignty—self-service compute, storage, and networking delivered through APIs, GitOps, and policy-as-code.
SolveForce designs and operates private cloud as a complete operating modelfabric (EVPN/VXLAN), platforms (HCI/OpenStack/Kubernetes), storage (SAN/NVMe-oF), Zero-Trust access, observability & evidence, chargeback/FinOps, and continuity—so the binder matches the build every single day.

🎯 Outcomes We Optimize

  • Agility without surprise — environments in minutes via IaC/GitOps; guardrails (deny-public, CMEK-required, tags enforced) and drift watchers protect day-2.
  • Deterministic performance — EVPN/VXLAN leaf/spine, right storage tiers (NVMe-oF/SSD/HDD), predictable latency for DB/VM/AI/VDI.
  • Zero-Trust by default — ZTNA for consoles/SSH/RDP, workload identity (no long-lived keys), WAF/API signing on portals.
  • Evidence on demand — configs/changes/approvals/tests/drills stream to /siem-soar for QBRs/audits.
  • Cost that behaves — showback/chargeback, capacity boards, reservation plans; unit economics ($/VM, $/vCPU, $/GB, $/GPU-hr).

🧭 Reference Architecture (colo/on-prem + hybrid)

1) Fabric & Interconnect

  • EVPN/VXLAN leaf/spine with Anycast gateways, QoS classes (EF/AF/BE), OOB network; MACsec on uplinks.

🔐 Security That Sticks (private baseline)

  • Identity-first: SSO/MFA; PIM/JIT for admins; workload identity for apps; no long-lived keys.
  • Boundary: WAF/Bot/DDoS for portals/APIs; token- & schema-validated calls; secure bastions behind ZTNA.
  • Custody: CMKs in HSM/KMS; vault secrets; rotation ceremonies logged; S/MIME/DMARC for ops communications.
  • Policy-as-code: deny-public, CMEK-required, tag enforcement, region & tenancy controls; CI checks + drift watchers.
  • Evidence: logs/configs/approvals/tests to SIEM; SOAR automations with approvals.

🧪 Acceptance Tests & Artifacts (we keep the receipts)

  • Fabric — EVPN/VXLAN validation, leaf/spine latency/jitter, QoS class tests, MACsec enablement; OTDR/light levels for inter-building links.
  • Compute — image integrity (SBOM/signatures), auto-heal/scale exercises; kernel/driver posture.
  • Storage — fio/VDbench (mixed read/write, sequential/random), snapshot/restore screenshots & checksums, replica lag; NVMe-oF queue/MTU checks.
  • Security — ZTNA admits, WAF/Bot events, KMS/vault rotations, DMARC/TLS-RPT headers.
  • DR — documented failover/failback timings; clean-point catalog; DR runbook screenshots.
    Artifacts stream to /siem-soar and assemble into QBR/audit packs.

💸 Showback/Chargeback (Private-Cloud FinOps)

  • Govern — mandatory tags/labels; budgets & alerts; policy stop on untagged resources.
  • Account — meter vCPU/RAM/IOPS/GB/GPU-hr, network egress; publish unit costs per team/service.
  • Optimize — rightsize VM flavors, storage tiering/lifecycle, consolidation & placement rules, reservation pools, energy-aware scheduling.
  • Forecast — capacity curves for compute/RAM/IOPS/GPU; quarterly planning with lead time for optics/UPS/racks.

🧱 Design Notes & Best Practices

  • Guardrails first: policy-as-code + drift watchers catch most mistakes before production.
  • Routed access > spanning tree: bound L2 domains; extend L2 only when justified.
  • NVMe-oF on IP? Use MTU 9000 end-to-end; size buffers; keep ECMP balanced.
  • Image discipline: SBOM & signatures; bake agents; refresh cadence.
  • Anycast for UC/API ingress: health-gated withdraw; test periodically.
  • Workload identity: replace static keys; rotate everything else with proof.
  • Quarterly drills: backups restore, DR failover, ZTNA revoke, WAF rule rollback—with artifacts.
