Compute

Compute Infrastructure

Virtual Machines

Metal Instances

Cloud GPU

Dedicated compute capacity under your governance—virtual machines for elastic workloads, bare-metal for latency-sensitive or compliance-bound applications, and GPU infrastructure for training, inference, and high-performance analytics. All engineered with isolation boundaries, predictable performance envelopes, and hardware-level control your public-cloud tenancy cannot guarantee.

Whether the workload is a stateful database cluster that refuses to share NUMA nodes, an ML training pipeline that saturates NVLink, or a fleet of lightweight VMs behind an internal platform team—compute starts with the right instance shape and ends with the operational discipline to keep it healthy.

Reality check

Public tenancy vs. private compute discipline

Shared tenancy pattern

When compute is a billing line item

Noisy neighbors steal cycles. Instance families change without notice. GPU availability is a lottery during training season. Compliance auditors ask where the hardware is and nobody can answer precisely.

  • Performance variance spikes during peak hours
  • GPU reservations expire before models finish training
  • No hardware-level isolation for regulated workloads
  • Capacity planning is reactive—overprovision or queue

Private compute delivery

When compute is an engineered surface

Dedicated silicon, measured performance envelopes, GPU scheduling tied to pipeline SLAs, and audit-ready hardware provenance from rack to workload.

  • NUMA-aware placement for latency-sensitive workloads
  • GPU clusters sized to actual training and inference cadence
  • Hardware provenance and lifecycle tracking per instance
  • Capacity forecasting tied to roadmap—not spot market luck

Compute Infrastructure

The physical and logical foundation underneath every VM, metal instance, and GPU allocation—server selection, rack architecture, network fabric, power and cooling envelopes, and lifecycle operations that keep compute predictable across years, not just benchmarks.

Server platform selection

CPU families, memory tiers, and storage buses chosen against workload profiles—not catalog defaults. Qualification includes thermal, firmware, and driver compatibility for your hypervisor or container stack.

  • Benchmark-validated against target workload patterns
  • Firmware and driver matrices maintained per generation
  • Vendor-neutral evaluation where standards allow

Rack and fabric architecture

Compute density, power distribution, and east-west fabric bandwidth designed together—so scaling does not hit a cabling or cooling wall at 60% utilization.

  • ToR and spine capacity modeled against growth plan
  • Power and cooling headroom documented per rack
  • Cable management tied to maintenance access paths

Lifecycle and refresh

Procurement, burn-in, production entry, warranty tracking, and decommission—each stage with documented acceptance and handoffs.

  • Asset records from PO through secure disposal
  • Refresh forecasting aligned to depreciation and workload growth
  • Spare strategy that balances cost against recovery time

Compute capability

Virtual Machine Instances

The most common unit of private cloud compute—VMs sized from lightweight dev containers to multi-socket database engines, all under your hypervisor, your policies, and your scheduling rules.

Instance families

General purpose, memory-optimized, compute-optimized, and storage-dense profiles mapped to workload archetypes—not T-shirt sizes that hide reality.

NUMA and pinning

CPU and memory affinity configured deliberately for latency-sensitive applications—databases, real-time processing, and financial engines that notice jitter.

Live migration

Maintenance-window flexibility without application downtime—validated per workload class, not assumed from hypervisor defaults.

Overcommit policy

Ratios set by workload tier—production gets guarantees, dev-test gets density. Both documented and measured, not discovered during incidents.

Image lifecycle

Golden images, patching cadence, and template governance so new VMs inherit security posture from day one—not after the first vulnerability scan.

Metering and chargeback

CPU, memory, storage, and network consumption tracked per tenant or project—evidence for internal billing and capacity reviews.

Compute capability

Metal Instances

Bare-metal servers allocated as single-tenant instances—no hypervisor overhead, full hardware access, and performance characteristics that do not share a socket with anyone else's workload.

When metal matters

Workloads that need direct device access, deterministic latency, or compliance regimes that prohibit shared hardware. High-frequency trading engines, some database tiers, license-bound software that counts physical cores, and bare-metal Kubernetes nodes for GPU or DPDK networking.

  • Full BIOS/UEFI control for firmware-sensitive stacks
  • SR-IOV and DPDK without virtualization overhead
  • License compliance where per-socket or per-core terms apply

Provisioning discipline

Metal instances provisioned through automation—PXE boot, firmware alignment, BIOS configuration, OS deploy, and network plumbing—not a technician with a USB stick.

  • Repeatable build from bare rack to production-ready
  • Configuration drift detection against declared state

Reclaim and reprovisioning

When a metal instance is returned, secure wipe, firmware reset, and requalification happen before the next tenant sees it—audit-grade evidence included.

  • Cryptographic erase where hardware supports it
  • Requalification test suite before return to pool

Cloud GPU Infrastructure

Purpose-built GPU clusters for training, inference, rendering, and HPC—designed around power density, high-bandwidth interconnects, and scheduling that treats GPU hours as a first-class resource, not a sidecar to CPU allocation.

GPU cluster design

NVLink, InfiniBand, or RoCE fabrics sized to training parallelism needs. Power and cooling engineered for sustained GPU load—not derated after 20 minutes.

  • Interconnect topology matched to distributed training patterns
  • Power and thermal budgets validated under sustained load
  • Multi-tenant scheduling when shared GPU pools are appropriate

Scheduling and orchestration

Job queues, preemption policies, and priority tiers so training pipelines and inference services share GPU resources without stepping on each other.

  • SLURM, Kubernetes GPU operator, or custom orchestration
  • Preemption rules tied to business priority, not first-come
  • Utilization dashboards that distinguish idle from reserved

Driver and framework lifecycle

CUDA, ROCm, driver versions, and ML framework compatibility tracked per cluster—upgrades tested before production training runs depend on them.

  • Compatibility matrices maintained per GPU generation
  • Staged rollout with validation against reference workloads
  • Rollback path when driver updates introduce regressions

Compute capability

Cloud GPU

GPU instances available on demand within your private cloud—allocated to workloads that need accelerated compute without managing the cluster infrastructure directly.

Training workloads

Multi-GPU and multi-node training with high-bandwidth interconnects, shared storage, and checkpointing so long jobs survive node failures without restarting from epoch zero.

Inference serving

Low-latency GPU allocation for model serving—autoscaling, batching, and model versioning infrastructure that keeps prediction endpoints healthy under variable load.

Rendering and simulation

GPU compute for ray tracing, CFD, molecular dynamics, or video encoding pipelines that are bursty but need deterministic throughput when active.

Fractional GPU

MIG, time-slicing, or vGPU partitioning for workloads that need acceleration but not an entire device—density without wasting silicon.

Data gravity

GPU nodes co-located with storage tiers so training data does not cross WAN links—locality engineered, not accidental.

Cost visibility

GPU-hours tracked per team, project, or experiment—evidence for FinOps reviews and capacity planning that goes beyond "we need more GPUs."

FAQ

Frequently asked questions

Yes. Most private cloud deployments combine all three—VMs for general workloads, metal for performance-critical tiers, and GPU nodes for ML or rendering. Network fabric and storage tiers are designed to serve all instance types coherently.

VMware vSphere, KVM/OpenStack, and Nutanix AHV for VMs. NVIDIA A100/H100/B200 and AMD Instinct for GPU. Specifics depend on workload requirements and licensing—we qualify against your stack, not a generic matrix.

Scheduling policies define priority tiers, preemption rules, and quotas per team or project. Utilization is metered so capacity reviews are evidence-based—not political.

End to end—procurement coordination, burn-in, production entry, warranty and RMA, refresh forecasting, and secure decommission with auditable records.

With automation in place, metal instances provision in minutes via PXE, firmware alignment, and declarative OS deploy. Lead time depends on whether spare inventory is pre-staged or requires procurement.
