Scaling AI: Strategic Infrastructure Investments for Optimal Performance

AI pilots often overlook teh critical role of infrastructure and hardware. However, seasoned experts emphasize that deploying high-value production workloads requires a strategic and ongoing focus on a robust enterprise-grade foundation.As organizations increasingly recognize the pivotal role of infrastructure in enabling generative, agentic, and other intelligent applications, smart investments become paramount.

The Growing Importance of AI Infrastructure

enterprises are significantly increasing their investment in AI infrastructure. According to IDC,organizations boosted spending on compute and storage hardware infrastructure for AI deployments by 97% in 2025 compared to the previous year. researchers predict global investment in this area will surge from $150 billion to $200 billion by 2028.

Did you Know? IDC predicts global investment in AI infrastructure will reach $200 billion by 2028.

Tho, simply spending more isn’t the key to success. John Thompson, author and head of the gen AI Advisory practice at The Hackett Group, notes that the competitive edge goes to those who scale most intelligently.

Avoiding the Pitfalls of Neglecting Infrastructure

Enterprises risk hindering the expansion and industrialization of AI workloads without careful planning and right-sizing of processors, accelerators, and upgraded power and cooling systems. These components are essential for handling the unprecedented data volume, movement, and velocity from edge to on-prem to cloud.

Infrastructure-related issues, such as performance bottlenecks, mismatched hardware, and poor legacy integration, are major obstacles to triumphant AI deployments. The growing interest in agentic AI further elevates the technological and financial stakes.

among tech companies, nearly 50% have agent AI projects underway, with the remainder planning to implement them within 24 months. These complex systems demand costly GPUs and TPUs to operate independently across multiple platforms.

The demanding requirements of AI workloads, including high-speed processing, networking, storage, and immense electrical power, are unlike anything most enterprises have built at scale. Careful analysis, planning, and IT upgrades are essential for readiness.

Key Principles for Scaling AI Infrastructure

While AI projects are unique, certain principles can guide successful scaling. Demands vary significantly between AI functions (training vs. inference) and types (machine learning vs. reinforcement learning). Business goals, budgets, technology debt, and available skills also play a crucial role.

There is no one-size-fits-all approach. Scaling AI infrastructure can involve increasing power (horizontally), upgrading existing hardware (vertically), or a hybrid approach.

Pro Tip: Consider a hybrid approach to AI infrastructure scaling to balance cost and performance.

A crucial mindset shift involves viewing AI not as a standalone submission but as a foundational capability embedded across business processes. Infrastructure must balance stability and security with the ability to quickly deploy purpose-built AI workloads optimized for specific domains.

Deb Golden, Deloitte‘s chief innovation officer, emphasizes that AI should be treated like an operating system, with infrastructure adapting to it. This requires a “fluid fabric” for dynamic allocation across platforms, possibly cutting costs by 30-40% and latency by 15-20%.

Embracing architectural modularity is key for long-term success. Ken Englund, EY Americas technology growth leader, highlights the importance of integrating different tools, agents, solutions, and platforms for flexibility and scalability.

Balancing Prudence and Power in Infrastructure Investment

Enterprise technology teams face the challenge of finding the “just right” investment levels in modern infrastructure to handle the demands of distributed AI. Under-investing can led to performance bottlenecks, while over-investing results in excessive costs and idle resources.

Simply throwing processing power at problems is not a winning strategy. Jobs with minimal AI needs are frequently enough routed to expensive GPU or TPU infrastructure,leading to long-term cost inefficiencies.

Right-Sizing AI Infrastructure

Strategic and tactical choices should be guided by the principle of having the right hardware in the right place at the right time, not simply the most powerful hardware everywhere. Successful scalers employ a “right-size for right-executing approach,” optimizing workload placement and leveraging policy-driven orchestration.

John Thompson emphasizes that AI scaling is not about brute-force compute.The goal is to optimize workload placement, manage context locality, and reduce redundancy.

Sometimes, the analysis can be simple. A generative AI system serving 200 employees might run fine on a single server.
