Ready to architect your way to AI success? Let's get started.
Q: What are the hidden costs when training AI across multiple clouds?
A. The AI landscape is inherently dynamic, with dominant players frequently being surpassed by innovative approaches. This constant evolution necessitates a multicloud strategy that provides flexibility to adopt new technologies and capabilities as they emerge. Organizations must be able to pivot quickly to leverage advancements in AI models, tools, and cloud services without being constrained by rigid infrastructure or high migration costs.
However, the rub is, as cloud AI training scales, network-related costs often become the most unpredictable part of the total budget. The main drivers are data egress fees, inefficient routing, and duplicated network infrastructure. Data egress charges grow rapidly when moving petabytes of training data between clouds or regions, especially when traffic traverses the public internet. Unoptimized paths add latency that extends training cycles, while replicating firewalls, load balancers, and SD-WAN devices in every environment creates CapEx-heavy, operationally complex networks. Security infrastructure for network traffic is often duplicated between clouds, leading to cost inefficiencies.
The solution lies in re-architecting data movement around private, software-defined interconnection. By replacing internet-based transit with direct, high-bandwidth links between cloud providers, organizations can reduce egress costs, improve throughput, and maintain predictable performance. Deploying virtual network functions (VNFs) in proximity to cloud regions also lowers hardware spend and simplifies management. Beyond addressing hidden cost, this approach gives IT leaders the agility to scale up or down with AI demand. As GPU clusters spin up, bandwidth can be turned up in minutes; when cycles finish, it can scale back just as fast. This elasticity avoids stranded investments while ensuring compliance and security controls remain consistent across clouds and regions.
By unifying connectivity and network services on a single digital platform, Equinix helps enterprises eliminate hidden costs, accelerate data movement, and ensure the network is a strategic enabler rather than a bottleneck for AI adoption. Specifically, Equinix Fabric helps customers create private, high-performance connections directly between major cloud providers, enabling data to move securely and predictably without traversing the public internet. By extending this flexibility, Equinix Network Edge allows VNFs such as firewalls, SD-WAN, or load balancers to be deployed as software services near data sources or compute regions. Together, these capabilities form a unified interconnection layer that reduces hidden network costs, accelerates training performance, and simplifies scaling across clouds.
Q: How do we keep AI training data legally compliant across countries and regions?
A. Data sovereignty and privacy regulations increasingly shape how and where organizations can process AI data. Frameworks such as GDPR and regional residency laws often require that sensitive datasets remain within geographic boundaries while still being accessible for model training and inference. Balancing those requirements with the need for scalable compute across clouds is one of the core architectural challenges in enterprise AI.
To address this, many enterprises choose to keep data out of the cloud but near it, placing it in neutral, high-performance locations adjacent to major cloud on-ramps. This approach enables control over where data physically resides while still allowing high-speed, low-latency access to any cloud for processing. It also helps avoid unnecessary egress fees, since data moves into the cloud for analysis or training but not back out again.
By establishing deterministic, auditable connections between environments leveraging private, software-defined interconnection keeps data flows under enterprise control, rather than relying on public internet paths. As a result, organizations can enforce consistent encryption, access control, and monitoring across regions while maintaining compliance. This also translates into greater control and auditability of data flows. Workloads can be positioned in compliant locations while still accessing global AI services, GPU clouds, and data partners through secure, private pathways. By combining governance with agility, Equinix makes it possible to pursue your most pressing global AI strategies while still reducing risk. Today, Equinix Fabric can support this approach by enabling private connectivity between enterprise sites, cloud regions, and ecosystem partners, helping data remain local while workloads scale globally. Equinix Network Edge complements this by allowing in-region deployment of virtualized security and networking functions, so policies can be enforced consistently without requiring physical infrastructure in every jurisdiction.
Together, these capabilities offer customers a foundation for compliant, globally distributed AI architectures. As a result, customers can create network architectures that not only reduce compliance risk but also turn regulatory constraints into a competitive advantage by delivering trusted, legally compliant AI services, based on the right data at the right time in the right place at global scale.
Q: How can I balance on-prem, cloud, and edge when running AI workloads without adding more complexity?
A. Determining where AI workloads should run involves balancing control, performance, and scalability. On-premises environments offer data governance and compliance, public clouds deliver elasticity and access to advanced AI tools, and edge locations provide low-latency close to users and devices. Without a unified strategy, this mix can lead to fragmented systems, inconsistent security, and rising operational complexity.
One effective approach is a hybrid multicloud architecture that standardizes connectivity and governance across all environments. Equinix defines hybrid multicloud architecture as a flexible and cost-effective infrastructure that combines the best aspects of public and private clouds to optimize performance, capabilities, cost, and agility. This design allows workloads to move seamlessly between on-prem, cloud, and edge based on performance, regulatory, or cost needs without rearchitecting each time. As a result, organizations can employ a hybrid multicloud architecture where policies, security, and connectivity are consistent across all environments. AI training can happen in the cloud with high-bandwidth interconnects, inference can run at the edge with low-latency access to devices, and sensitive datasets can remain on-premises to maintain regulatory compliance. This architecture enables seamless interconnection across clouds, users, and ecosystems, supporting evolving business needs.If customers utilize Network Edge VNFs they can access a control plane to manage traffic flows seamlessly across these environments, ensuring workloads are placed where they deliver the most business value with a predictable cost. It also enables the deployment of virtual network functions such as firewalls, load balancers, and SD-WAN as software services, reducing hardware overhead and improving consistency. Together, they create a common network fabric that simplifies operations, supports workload mobility, and maintains governance across diverse environments.
As a result, customers can minimize complexity by centralizing management, turning what used to be a fragmented sprawl into a unified, agile, and compliant AI operating model.
Q: How to predict and control network spend when running apps across multiple clouds?
A. As AI and multicloud workloads scale, network costs often become the least predictable element of total spend. Massive east-west data movement between training clusters, storage systems, and clouds can trigger unexpected egress and transit fees, while variable routing across the public internet adds latency and complicates cost forecasting. These factors can make it difficult for IT and finance teams to align budgets with actual workload behavior.
A more sustainable approach is to build predictability and efficiency into the interconnection layer. By replacing public internet paths with dedicated, software-defined connections, organizations can achieve elastic bandwidth scaling while having predictable billing. This model not only ensures stable and reliable network performance but also enhances cost transparency, enabling businesses to optimize their connectivity expenses while supporting evolving operational demands.
Equinix Fabric supports this model by enabling private, high-performance connections to multiple clouds and ecosystem partners from a single port, fostering predictability in network performance. Equinix Network Edge complements this by allowing network functions such as firewalls, SD-WAN, and load balancers to be deployed virtually, reducing CapEx and aligning spend with actual utilization. Together, they deliver a unified network architecture that stabilizes performance, enhances cost transparency, and enables organizations to scale bandwidth effectively while managing costs in alignment with their AI and multicloud workloads.
Q: What’s the best way to ensure my AI workloads don’t go down if one cloud region fails?
A. AI workloads are highly distributed, and regional outages can disrupt training, inference, or data synchronization across clouds. Relying on a single provider or static internet-based paths introduces latency and failure risks that can cascade across operations. Building resilience into the interconnection layer ensures continuity even when one region or cloud becomes unavailable.
The key is to design for multi-region redundancy with pre-established, high-performance failover paths. By maintaining secondary connections across clouds and geographies, organizations can automatically reroute workloads and traffic without interruption or loss of performance.
Equinix Fabric enables this design by providing software-defined, private connectivity to multiple cloud providers and regions. Equinix Network Edge complements it by supporting virtualized global load balancers, SD-WAN, and firewalls that dynamically redirect traffic and enforce security policies during failover. Together, they create a resilient, globally consistent architecture that maintains availability and performance even when individual cloud regions experience disruption.
