Who Should Ditch Public Cloud and When?

“Just move everything to the cloud” sounded simple until invoices and compliance audits piled up. Private cloud as a service (PCaaS) offers a different path: the elasticity of cloud delivered on hardware you control, operated for you by specialists like iShift + Platform9.

Why public-cloud fatigue is rising?

  • Runaway spend.

  • Budget control is now #1 pain.

  • License sticker shock.

What is private cloud as a service?

    1. Managed platform: you supply servers or colo; iShift runs the stack as a SaaS-like service.

    2. Open-source DNA: Kubernetes, KVM & OpenStack power VMs and containers (good-bye VMware tax).

    3. Elastic billing: pay per core / GB RAM with no egress surprises.

Five signals it’s time to switch

  • You face strict compliance (HIPAA, GDPR, FedRAMP) that frowns on multi-tenant drift.

  • Workloads are predictable; reserved instances feel overpriced.

  • Egress or license costs suddenly dwarf infrastructure value.

  • You need single-digit-ms latency for trading, IoT, or real-time analytics.

  • GenAI / GPU burn: hourly cloud GPU pricing vaporizes margins.

Why iShift + Platform9 make PCaaS painless

  • 2-week assessment → hardware rightsizing, TCO model, compliance gap map.

  • 24 / 7 SRE operations – patching, monitoring, incident response handled for you.

  • Built-in cyber resilience – zero-trust access, SIEM hooks, DR run-books from day one.

  • Quarterly FinOps reviews – so your private cloud as a service stays cheaper than public.

Success snapshot
A data-services firm moved analytics clusters to PCaaS, slashing compute spend by 75 %.
“Running in the public cloud cost us four times more,” their CTO said after switching to Platform9.

30-Day Private Cloud as a Service Pilot

WEEK          MILESTONE

1     Kickoff, TCO comparison, compliance checklist

2    Pilot migration of 10 VMs / containers

3    Production rollout + security hardening

4    Knowledge-transfer workshops & hand-off

Quick self-checklist

If you answer YES to 3+ of these, explore PCaaS now:

  • Are cloud invoices > 20 % over forecast?

  • Do data-sovereignty rules block certain workloads from AWS/Azure?

  • Is GenAI compute throttled by on-demand GPU pricing?

  • Still carrying costly VMware licenses post-Broadcom?

  • Does security struggle with multi-tenant risk?
