Mastering the operational model challenge for distributed AI/ML infrastructure

Mastering the operational model challenge for distributed AI infrastructure

The NVIDIA GTC event has concluded. I recently returned from this event in San Jose, still buzzing with excitement from the incredible announcements and palpable energy throughout the conference. The rapid pace of innovation in the AI/ML infrastructure space was clear, with NVIDIA leading the way. NVIDIA CEO Jensen Huang delivered an awe-inspiring keynote, revealing previously unimaginable breakthroughs. Among the highlights was the launch of the GB100 Blackwell system, the fastest AI supercomputer ever built. As I witnessed the contagious enthusiasm of the tech community gathered there, it became clear that we are at a watershed moment in democratizing Artificial Intelligence.

Jensen Huang’s approach to running NVIDIA as its CEO is deeply rooted in a core belief in continuous innovation and solving problems that conventional computing cannot address.

This philosophy will drive NVIDIA to continue to break new frontiers in AI and deliver innovations that we may not even have heard of yet.

After viewing the rack systems constructed by NVIDIA and numerous others from their ODM and hardware partners at the event, and conversing with several attendees, the situation became clear to me. There is a pronounced demand for private AI/ML infrastructure intended for widespread distribution.

Several factors contribute to the demand for on-premises, edge, or colocation-based AI/ML workloads. These include geopolitical events, economic headwinds, and industry-specific requirements.

With global tensions and supply chain disruptions persisting, organizations increasingly aim to reduce reliance on third-party providers. They seek greater control over their critical infrastructure and data.

Furthermore, certain industries have unique workload characteristics that make private clouds, edge, or colocation facilities more appropriate than public cloud offerings.

Organizations in fields such as drug discovery, genomics research, autonomous driving, oil and gas exploration, SASE edge security, and telco 5G/6G operations often face specialized workloads. These tasks demand consistent, high-performance computing resources when run in regional data centers.

Scientific research, AI/ML model training, and data-intensive processing tasks in these fields can often be managed more cost-effectively in private cloud environments or at the edge, closer to where the data is generated.

The operational challenges of AI/ML infrastructure

Data scientists, researchers, and AI/ML teams require flexible, high-performance infrastructure to support the full lifecycle of development – from data experimentation and model training to inferencing at scale. However, managing the underlying compute, storage, and networking resources across a distributed footprint presents immense operational hurdles.

ML and data teams’ requirements

Data scientists and researchers want to focus on modeling and application development rather than dealing with infrastructure complexity. They need on-demand access to scale resources for intensive data processing, model training, and inferencing workloads without operational overhead.

MLOps and DevOps demands

On the other hand, MLOps and DevOps teams require total control, high availability, and fault tolerance of the on-premises AI/ML infrastructure. Ensuring reliable model deployment, continuous delivery, and governance is critical but extremely difficult without automation.

Operational consistency challenges

Spanning this AI/ML infrastructure across core data centers, public clouds, and edge locations significantly compounds the operational burden. Maintaining consistency in deployments, monitoring, troubleshooting, and upgrades becomes exponentially more complex in a heterogeneous distributed environment.

Streamlined operations needed

To unlock AI/ML’s full potential, enterprises need a streamlined operational model. This model must feature high automation, offering self-service provisioning, built-in redundancy, and unified lifecycle management across the entire distributed footprint. Only with this setup can data teams innovate rapidly. At the same time, MLOps and DevOps can ensure scalability, reliability, and governance.

Achieving a cloud operational model for distributed AI/ML infrastructure

To effectively operationalize AI/ML infrastructure across a distributed footprint spanning core data centers, public clouds, and the edge, enterprises require an operational model with the following characteristics:

Kubernetes as a consistent compute fabric

Adopting Kubernetes as the foundational compute fabric provides a consistent abstraction layer with open APIs for integrating storage, networking, and other infrastructure services across the distributed footprint. This establishes a uniform substrate for deploying AI/ML workloads. Kubernetes is a necessary foundation, but not sufficient for a complete operational model.

Closed-loop automation

Public cloud providers have made significant investments in developing highly automated closed-loop systems for the full lifecycle management of their infrastructure and services. Every aspect – from initial provisioning and configuration to continuous monitoring, troubleshooting, and seamless upgrades – is driven through intelligent automation.

Manual operations that rely on people executing scripts and procedures may suffice at a small scale, but quickly become inefficient, inconsistent, and error-prone as the infrastructure footprint expands across distributed data centers, public clouds, and edge locations.

Enterprises cannot realistically employ and coordinate armies of operations personnel for tasks like scaling resources, applying patches, recovering from outages, and managing complex redundancy scenarios.

What’s required is an operational model based on closed-loop automation. This model leverages telemetry data, machine learning, and codified runbook procedures. It autonomously detects and resolves issues, optimizes resource usage, and enforces compliance across the entire footprint. Self-healing capabilities enable resilient self-management. Meanwhile, unified automation eliminates fragmented islands of infrastructure. Only with this operational convergence can organizations achieve the agility, efficiency, and reliability needed. This is essential to fully harness AI/ML at a hyperscale level.

Platform engineering at scale with a cloud management plane

A comprehensive operational and management plane is needed, possessing the following characteristics:

  • Reduced maintenance costs by aggregating all distributed infrastructure behind a single management pane.
  • Rapid and repeatable remote deployments to hundreds or thousands of distributed cloud locations with consistent template-based configuration and policy control.
  • An operational SLA through automated health monitoring, runbook-driven resolution of common problems, and streamlined upgrades.

Building an enterprise-grade, internal cloud management plane requires hundreds of highly skilled cloud software and DevOps engineers. They work full-time on automation, self-healing capabilities, and unified lifecycle management. Very few organizations can afford this level of platform engineering talent and headcount.

Continuous operational improvement

An operational model that can dynamically improve and add new features/capabilities over time through a virtuous cycle of operational data, analytics, and continuous integration. Ad-hoc scripting approaches rapidly become stale and obsolete.

Enabling collaborative multi-stakeholder operations for AI/ML infrastructure

Operating a distributed AI/ML infrastructure is not just a technical challenge. It also requires coordination and shared responsibilities across multiple stakeholders. Data science, MLOps, DevOps, infrastructure, security, and compliance teams all have key roles. They ensure the success of the end-to-end lifecycle. Additionally, managed service providers and vendors may be involved in supporting different parts of the stack.

To enable this collaborative operating model, organizations need an open platform that provides clear separations of concerns with appropriate visibility, access controls, and automation capabilities tailored to each stakeholder’s needs.

Comprehensive telemetry, observability, and AIOps-driven analytics are critical for stakeholders to efficiently triage and resolve issues through a cohesive support experience. Trusted governance policies that span the hybrid infrastructure are also required for compliance and enabling cross-functional cooperation.

By designing for multi-tenant, multi-cluster operations from the outset, the platform can foster seamless collaboration across this ecosystem of internal and external entities.

Unlocking the potential of distributed AI/ML infrastructure

To truly realize the potential of distributed AI infrastructure, the industry must address the operational model challenge, allowing enterprises, independent software vendors (ISVs), and managed service providers (MSPs) to provide benefits on par with public clouds.

Embracing such an operational model, organizations can harness the power of AI/ML workloads on-premises or in colocation facilities without the complexities and inefficiencies associated with manual management. They can achieve the scalability, reliability, and cost-effectiveness needed to compete in an increasingly AI-driven world.
