Is Your AI Ecosystem Dense Enough for Agentic Workflows?

Back in 2022, if you’d asked a network architect which ecosystem partners they connected to most frequently, the answer likely would have been the cloud hyperscalers.

Now, they’re still building multicloud architectures, but the definition of “multicloud” has changed for the AI era. The hyperscalers have been joined by neoclouds, model providers, SaaS providers, data platforms and more. These partners provide the GPUs, models, datasets, tools and services required to execute an enterprise AI strategy. To further complicate things, these partners are often distributed across different regions and environments.

Before AI, ecosystem connectivity was a simple procurement exercise. Businesses just needed a few cloud on-ramps, which they could set and forget.

After AI, the role of the network architect has become much more complicated:

• They need to figure out how to reach distributed partners in a reliable, cost-effective manner.
• They need to avoid high latency that causes poor user experience and sovereignty issues that cause non-compliance and loss of control.
• They need network agility to ensure the business can support AI agents that perform hundreds of actions in the time it takes a human user to perform one.

Agentic AI in particular is changing network requirements. The agents must be empowered to call different tools, datasets and partner agents, wherever those resources are hosted. If agents can’t reach the needed endpoints reliably, then the entire value proposition of deploying AI agents starts to break down.

Agents also present challenges that human users don’t. Because they operate so quickly and hop across different environments so easily, the impact of inefficient networking can compound without business leaders even knowing it.

Consider an agent chain that needs to make 10 different hops across AWS, Azure, Google Cloud and CoreWeave in different cloud regions. Routing this chain over the public internet may seem like the simplest option. But since the internet doesn’t offer dedicated bandwidth or direct routing, each hop compounds latency and egress costs, while creating security and compliance risk. A single hop in the chain may not appear alarming if you look at it in isolation, but the aggregate is what really matters.

In this hypothetical example, the application needs to execute 10 sequential hops across the four different providers. Using the internet, each hop would follow best-effort routing with no performance SLAs. The average round-trip delay for each hop might be a manageable 50 milliseconds. However, the agent chain would accumulate 500 milliseconds of total latency across all hops, which is more than enough to disrupt any AI application.

Latency isn’t the only thing compounding. Each hop is also a token generation event with its own cost, a boundary crossing with its own compliance exposure, and a point of failure that can break the entire chain. Network time is the part of that stack an enterprise can actually control.

The problem is that it’s a case of “death by a thousand cuts.” Optimizing any individual hop wouldn’t make a meaningful impact on application performance. The only way to address the wider issue is to optimize the entire network architecture for ecosystem density and low-latency connectivity.

The definition of ecosystem density is changing

Businesses have changed the way they work with ecosystem partners. It makes sense that the benefits of ecosystem density have changed as well.

Ecosystem density used to mean that when you needed a particular partner, it was quick and easy to find and connect with them. Businesses were attracted to interconnection hubs because of the network effect they provided. Many potential partners gathered in these hubs, so there was a good chance that their chosen partner was already in the building. They could quickly connect to that partner via provisioning ticket, rather than a complex, time-consuming infrastructure project.

The number of external endpoints the network needed to reach was small and stable. The value of ecosystem density was measured in how much time the organization saved during procurement. Unlike today, it had nothing to do with how well the application performed after it was deployed.

Agentic AI changes the density equation

Ecosystem density is much more than just a procurement benefit now. To put it simply, you can’t do agentic AI without it.

Today’s agents offer both intelligence and agility: They can automatically determine which providers they need to connect with and then do so in real time. If the network becomes a bottleneck, preventing agents from reaching their intended partners quickly and easily, then all their intelligence and agility will go to waste.

As mentioned earlier, a chain of agent functions routed across different providers via the public internet quickly compounds latency, costs, and security and compliance issues. But each hop also represents a potential point of failure. If one transaction fails, then the entire chain breaks down. This further highlights why it’s so important to reach partners in the right places, using the right networking technology.

Ecosystem density keeps more of those hops local, which changes what each one costs in latency, egress fees, and compliance exposure. And when enterprises use private interconnection to capitalize on ecosystem density instead of the public internet, they get direct routing to ensure deterministic latency and mitigate non-compliance risk.

There’s an economic dimension to this as well. Most hops in an agent chain don’t need a frontier model. Parsing a request, classifying an intent or extracting a field can run on an open-weight, inexpensive model, hosted on private infrastructure or a low-cost neocloud, with escalation to a frontier model only when the task genuinely warrants it.

That kind of tiering rarely lives inside a single provider’s lineup, so it depends entirely on what’s reachable: the open-source model running locally and the frontier model available over private interconnect. If you can only reach one, you can’t tier, and your agent economics get set by your most expensive hop.

Flexibility is essential, and it depends on ecosystem density

The AI landscape is always changing, and your chosen ecosystem partners are likely changing as well. There’s no guarantee that today’s leading neoclouds and model providers will still be on top a few years from now. Maintaining the ability to switch providers easily allows enterprises to meet their always-changing needs around performance, pricing and privacy.

Ecosystem flexibility depends on a neutral infrastructure foundation that makes alternative providers easily accessible. If the replacement is available within the same connected ecosystem as the existing endpoint, then switching is quick and easy. If not, then it’s more than just a switch; it’s a migration, and it will likely take months to complete.

In June, geopolitical events reinforced the importance of model flexibility. A U.S. export control directive required Anthropic to suspend access to two of its newest models for any foreign national. Because nationality couldn’t be verified in real time, the company disabled both models for every customer worldwide, including U.S. customers. They stayed offline for roughly three weeks.

The lesson wasn’t only about contracts. The businesses that recovered quickly did so because they already had an alternative available: a second model, in the same connected ecosystem, on neutral infrastructure. Those that had hard-wired one provider into one path had to negotiate new agreements and provision new circuits, which made disruption inevitable.

Businesses also need ecosystem density to respond to changing regulatory conditions. For instance, the Digital Operational Resilience Act (DORA) increases scrutiny on financial institutions in Europe, particularly their relationships with third-party providers. These financial institutions must be prepared to prove that they’re not overly reliant on any single vendor. This means showing that they have access to many different partners, and that they’d be able to reach those partners quickly should the need arise.

Inference is consolidating in metros, not crossing continents

When a company publishes its total number of ecosystem partners globally, that doesn’t reflect the way that ecosystem density impacts real AI workloads. That’s because those workloads don’t operate globally; they operate in specific places, like Frankfurt, Sydney or São Paulo.

A workload is subject to the conditions and regulatory requirements of the metro in which it’s deployed, so the only ecosystem that really matters is the one that’s in that same metro. An ecosystem partner located on the other side of the world is irrelevant in this context.

To truly understand ecosystem density, enterprises leaders must ask themselves several questions:

• Where do our AI agents run?
• Which model providers, neoclouds and data platforms do our agents need access to?
• Are those partners available in the same metros where the agents need to run?

When leaders consider ecosystem density with this level of granularity, it paints a different picture than the global statistics do. The number of ecosystem partners that are accessible to AI agents in the right places is likely much smaller than they initially thought.

Density plus control equals agile, intelligent networking for AI

Equinix colocation data centers gather many different ecosystem partners on the same vendor-neutral foundation, including 9 of the top 10 neoclouds and 8 of the top 10 model providers. These providers land in strategic enterprise hubs like Washington, D.C., Chicago, Dallas, Silicon Valley, Amsterdam, Frankfurt, Singapore and Tokyo. In fact, Silicon Valley alone has 6 of the top 10 neoclouds and 7 of the top 10 LLMs present. This ensures that connectivity and paths to their services are deterministic, performant and secure. Our Equinix data centers help bridge the gap between local ecosystem density and globally distributed workloads.

However, just being adjacent to partners is not enough to capture the full value of what they have to offer. Enterprises need control over their networking to ensure they can quickly align their connections to their intended business outcomes. Equinix offers private connectivity that enables this, including solutions that support sovereignty boundary enforcement, observability into changing real-time conditions, and direct cloud-to-cloud routing between different partner environments.
