Enterprise AI Stack Deployment Best Practices

A Practical Guide to Architecting Your Internal AI Infrastructure

What Is an AI Stack?

An AI stack is the full-layered system your enterprise needs to build, train, and deploy AI models. It includes compute, data pipelines, LLMs, orchestration, and observability. Whether you're starting your first AI project or scaling internal ML operations, having a robust stack is critical to your success.

Open LLMs Provide Freedom & Customization

Embrace open constructs of AI with foundation models you can run in your own environment. Avoid vendor lock-in and keep sensitive data in-house by fine-tuning your own models.

Recommended Open LLMs:

GPU Selection: NVIDIA vs AMD

Choosing the right GPU architecture is crucial for your AI stack's performance and cost-effectiveness. Here's a comprehensive comparison to guide your decision:

Factor NVIDIA AMD
Ecosystem Maturity Industry-standard; broad support in PyTorch, TensorFlow, and Hugging Face Improving, especially with ROCm support in PyTorch
Software Stack CUDA, cuDNN, TensorRT; highly mature ROCm — open source, less mature but growing
Model Compatibility Wide out-of-the-box compatibility Selective compatibility; tuning may be required
Developer Tools Extensive (Nsight, Triton, NGC containers) Improving; less mature ecosystem
Performance (per watt/$) B200, B300, DGX GB200 NV72, DGX GB300 NV72 Competitive, especially on FP16 workloads
Vendor Lock-In More likely (CUDA proprietary) Lower risk (ROCm is open-source)
Cost Typically higher More cost-effective at similar performance levels
Cloud Support Supported by all major cloud providers Limited but growing
Inference Optimization Highly optimized (TensorRT, Triton) Fewer optimized inference libraries

When to Choose NVIDIA

  • You need the widest compatibility with open-source models and training pipelines
  • Your team relies on CUDA-accelerated libraries and frameworks
  • You want access to mature tooling and prebuilt containerized environments (e.g., NVIDIA NGC)
  • You're building a latency-sensitive inference stack with real-time requirements

When to Choose AMD

  • You want to avoid vendor lock-in and embrace an open ecosystem (ROCm)
  • You're focused on cost-efficiency at scale and can optimize your models accordingly
  • You're building internal capabilities and have control over the training environment
  • You prefer to invest in open hardware/software infrastructure for long-term flexibility

Hybrid Approach: For some enterprises, deploying a heterogeneous AI stack (NVIDIA + AMD) can strike a balance between cost and performance. Use NVIDIA for critical, latency-sensitive workloads and AMD for batch training or lower-priority jobs.

Networking & Compute: Why Standardization Wins

Your infrastructure needs to scale, not lock you in. That's why we recommend NVIDIA, AMD or Broadcom 400G Super NICs. An XPU or accelerator node will consume up to four 400G Ethernet adapters or Super NICs. The IEEE is currently ratifying 1.6T Ethernet, which will allow the next generation of XPUs to scale up 3.2T bps of I/O from GPU to GPU.

Standard Ethernet Proprietary Fabrics
Vendor-agnostic and scalable Vendor lock-in
RoCEv2, RDMA over TCP/IP Hard to integrate
Supports cloud-native stacks Requires niche tuning
Lower TCO Higher complexity

Key Principle: Build once, scale everywhere without being locked into a vendor-specific ecosystem.

Internal Enablement Made Easy

Arm your internal teams with a reference stack and templates:

Blueprint Templates

Pre-approved AI stack blueprints for rapid deployment

CI/CD Integration

GitOps + CI/CD integrations for seamless workflows

Monitoring Stack

Model monitoring with Prometheus + Grafana

Data Governance

Model tracking with MLflow/W&B for compliance

Modular, flexible architecture that evolves with your needs

Data Colocation

Keep your data close to your LLMs for optimal performance

Vendor Independence

Avoid lock-in with open standards and interoperable components

Enterprise LLM Stack Frequently Asked Questions - FAQ

What is a production-ready enterprise LLM stack?

A production-ready enterprise LLM stack is a modular architecture designed to support the full AI lifecycle—training, fine-tuning, and inference—using scalable infrastructure, open-source frameworks, and secure deployment patterns that align with enterprise requirements.

Why do enterprises need a standardized AI stack?

A standardized stack provides consistency across teams, reduces integration friction, supports reproducibility, and ensures security, governance, and observability for scaling LLM-powered applications across departments.

What infrastructure is required for large-scale LLM training and inference?

Enterprises need high-performance compute (GPUs or AI accelerators), ultra-low-latency networking (400G/800G Ethernet or InfiniBand), and scalable storage. Support for containerized workloads and orchestration frameworks like Kubernetes is critical to handle modern LLM workloads.

Which model frameworks and serving tools are recommended?

Commonly used frameworks include PyTorch, Hugging Face Transformers, DeepSpeed, and Megatron. For serving, tools like NVIDIA Triton, vLLM, and BentoML enable efficient, scalable LLM inference and integration with enterprise workflows.

How does this stack support open-source alignment?

The AI-Stack approach embraces open-source components like PyTorch, Kubernetes, and SONiC-based networking. This allows enterprises to avoid lock-in while maintaining flexibility and interoperability across evolving LLM ecosystems.

How can I ensure enterprise-grade security and observability?

The stack supports secure multi-tenancy, role-based access, encrypted communication, audit logging, and integration with enterprise observability platforms—ensuring AI workloads meet corporate security and compliance standards.

How should data pipelines be designed for enterprise LLMs?

Enterprise-grade data pipelines should ensure high-throughput, versioned, and secure movement of training and inference data. They must support distributed loading, batch processing, streaming ingestion, and be integrated with feature stores and lineage tools.

What is LoRA and how is it used in enterprise fine-tuning?

LoRA (Low-Rank Adaptation) is a parameter-efficient fine-tuning method for LLMs that allows enterprises to quickly specialize foundation models using smaller compute resources. It reduces training costs and simplifies deployment while retaining model performance.

What role do AI agents play in enterprise applications?

AI agents orchestrate LLMs to perform goal-directed tasks using memory, planning, and tool use. In the enterprise, agents are deployed for customer support, automation, data extraction, and RAG (retrieval-augmented generation) applications with secure control layers.

Should I use SONiC or InfiniBand for my AI network fabric?

SONiC on 400G/800G Ethernet offers vendor-neutral, cost-effective, open networking, ideal for scale-out inference and hybrid clusters. InfiniBand provides low-latency, RDMA-optimized throughput, ideal for tightly coupled training workloads. Many enterprises use both depending on the workload.
