Modernizing IT Architecture to Support Agentic AI

Modernizing IT Architecture for Agentic AI Foundation

Beyond automation, Agentic AI is a fundamental shift in how enterprise technology operates and how organizations function. Previous automation tools could handle only fragments of a process, always leaving edge cases for humans to step in. Now, that’s changing. AI agents can reason, collaborate, and coordinate actions, enabling them to complete complex, multistep workflows that once relied entirely on human judgment. They don’t just follow instructions. They adapt, learn, and make contextual decisions along the way.

It’s easy to see why this could be transformative. From better decision-making to streamlined operations and improved customer experiences, the potential impact spans the entire business. The question for leaders is no longer how effective AI agents can be but how fast they can prepare to deploy AI agents safely and effectively.

As executives start exploring what agentic AI means for their strategy, talent, and competitive edge, they’ll also need to face a deeper challenge: their IT architecture. Agentic AI builds on the rise of composable, cloud-based architectures, the microservices frameworks many enterprises already use. But to fully unlock its value while managing its risks, organizations must rethink how AI integrates across every layer: systems, data flows, processes, and governance.

For AI agents to work safely at scale, they need real-time context, explainability, and guardrails that ensure secure, cost-effective execution. Today’s enterprise systems aren’t yet designed for thousands of autonomous agents working simultaneously, but that’s exactly the frontier we’re heading toward.

Architecture Must Evolve to Support Agentic AI

It’s important to note that Agentic AI isn’t to replace existing enterprise systems, it’s meant to complement them. The goal is meaningful integration, not disruption. Tech leaders will need to define clear boundaries, roles, and safeguards so these intelligent systems enhance what already works instead of overwhelming it.

AI agents are best suited for complex, non-deterministic challenges, the kind that cut across multiple business domains, depend on unstructured data, require contextual reasoning, and rely on real-time inputs. These are exactly the areas where traditional automation has struggled and where human intervention has always been essential, until now.

Within this new landscape, two layers of agents typically work together:

  • Orchestrator agents function like project managers. They oversee entire workflows, break them into smaller tasks, track progress, and adapt as conditions change.
  • Task agents handle individual assignments, execute actions, and report back their results. The orchestrator then consolidates outputs, refines decisions, and keeps the overall process on track.

This orchestration model gives enterprises both autonomy and control, combining speed with oversight.

Modernizing the Core Platform

To unlock the full potential of agentic AI, many organizations will need to modernize their core technology foundation. Agents can only perform well if they can quickly locate and interact with core business capabilities in real time.

That often means reworking legacy, batch-based systems into more dynamic architectures: systems that are API-driven, event-responsive, and modular. Industry-standard frameworks such as domain-specific architecture networks can accelerate this shift, but modern and legacy systems will likely need to coexist for some time, creating short-term complexity.

Ensuring Interoperability

As AI agents proliferate across the enterprise tech stack, interoperability becomes mission-critical. Standards like the Model Context Protocol (MCP) and frictionless integrations will help unify different systems and prevent siloed operations.

In reality, most organizations will operate a hybrid ecosystem, combining:
• Custom-built agents developed by engineering teams,
• Prebuilt agents embedded within vendor platforms, and
• Dynamically generated agents running inside data environments.

Even development frameworks themselves are becoming agentic. In the near future, a software development lifecycle (SDLC) agent can coordinate specialized agents for design, analysis, engineering, and quality assurance, across the life-cycle. All collaborating to deliver a product from concept to deployment.

Distributing Accountability

Building agentic capability isn’t just an IT project, it’s an enterprise-wide shift. While central platform teams will manage the underlying AI infrastructure, ownership must be distributed. Business domains need to take responsibility for designing, testing, deploying, and monitoring their own agents.

This will require making domain knowledge easily accessible, including product documentation, business logic, data models, and feature stores, so that agents can learn and operate effectively. In short, the success of agentic AI depends on how discoverable your organization’s intelligence truly is.

Scaling Data Access

Finally, none of this works without broad, scalable access to both structured and unstructured data. Many companies still lack reliable ingestion pipelines for content like documents, emails, recordings, images, or videos, yet that’s where much of the tacit knowledge resides.

These unstructured sources are vital for agentic reasoning, particularly in exception-driven processes that fall outside traditional databases. Enterprises that build infrastructure to unify both structured and unstructured data will gain a major edge, enabling AI agents to generate richer insights, more personalized experiences, and faster decisions at scale.

Updating Governance and Controls

As AI agents start making more decisions, governance and control frameworks must evolve. Traditional oversight won’t cut it. Organizations will need real-time explainability, so every action taken by an agent can be traced and understood; behavioral observability, so unusual patterns are detected early; and adaptive security, so systems can adjust to new threats in real time.

This isn’t just about risk management, it’s about trust. Transparent AI behavior helps maintain customer confidence and protects against regulatory and reputational risks. At the same time, technology leaders must monitor compute volatility, managing costs through dynamic resource allocation, smart scheduling, and AI-native FinOps practices. As workloads scale, so must the efficiency with which they’re managed.

Shifting the Engineering Paradigm

Agentic AI doesn’t only change business processes, it reshapes how software is built and maintained. Engineering and DevOps practices will need to adapt to a world where agents evolve and learn continuously. That means new standards for testing, monitoring, deployment, and lifecycle management to ensure reliability as these systems grow more autonomous.

In many cases, AI agents will take over parts of day-to-day software development, from coding and testing to deployment and system maintenance. This shift will free engineers to focus on higher-value work: designing architectures, optimizing performance, and driving innovation. In effect, engineers will move from managing individual applications to managing intelligent ecosystems.

Reimagining Agent Experience and Access

In this new environment, agents become first-class citizens in the enterprise ecosystem.

As channels, they’re emerging as the next major interface for customer and employee engagement, on par with websites, mobile apps, and contact centers. As citizens, they operate as embedded participants in business operations, empowered to act, make decisions, and collaborate across workflows and systems.

This will require a complete reimagining of experience design. Human interactions will increasingly take place through conversational interfaces, while agent-to-agent collaboration will power behind-the-scenes automation across departments, systems, and even partner networks.

To make this work at scale, and safely, organizations must establish robust frameworks for identity, consent, and fine-grained access control. Clear boundaries between human and machine responsibility are essential for trust, safety, and accountability.

The Implementation Imperative

Over the next three to five years, organizations are expected to direct 5–10% of their total technology spending toward foundational capabilities: agent platforms, communication protocols, real-time data pipelines, and next-generation security and observability frameworks.

As adoption accelerates, spending on agentic AI could grow substantially, with up to half of enterprise technology budgets ultimately supporting agents embedded across business functions. Despite the upfront cost, the long-term economics are favorable: efficiency gains and smarter processes will deliver outsized returns.

To succeed, investments should stay focused and outcome-driven, with clear business value from the start. Most successful transformations follow four essential motions:

1. Start small, scale fast.

Focus on a few high-impact business domains first. End-to-end process redesign generates quick wins, lowers cost per agent, and builds momentum for enterprise-wide adoption.

2. Assess readiness.

Evaluate your current architecture for agentic compatibility, from interoperability to event-driven systems and modernized vector databases. Lay the groundwork for scalable development toolchains.

3. Embed guardrails early.

Build in observability, governance, and cost controls from day one. Traceability and accountability must be native to the system, not patched on later.

4. Use AI to scale AI.

Leverage agentic systems within your own transformation, automating development, monitoring, and reporting to accelerate progress and contain costs.

Moving into the Agentic Era

The shift toward agentic AI is already underway, and it’s moving fast. Companies that invest now in architecture, talent, and governance will lead the next generation of intelligent enterprises. Those that wait risk falling behind as AI reshapes every aspect of how work gets done.

Success won’t come from technology alone. It will depend on decisive leadership, the courage to redesign core processes, and the ability to integrate AI responsibly, balancing autonomy with oversight, and innovation with control.

The organizations that move boldly today will be the ones defining how the agentic enterprise of tomorrow truly operates.
