An AI cluster becomes productive when its resources can work together. GPUs need access to data, applications need reliable service endpoints, and users need permissions that let them work within clearly defined boundaries. As clusters expand, maintaining those connections becomes an increasingly consequential part of operating them.
Different teams bring different networking needs, from isolated training environments to inference services that depend on controlled access to data and applications. Supporting those use cases requires strong tenant isolation, automated provisioning, policy enforcement, and flexible controls for addressing, DNS, and connectivity. Teams need the freedom to configure their environments while administrators maintain consistent boundaries as workloads and resources change.
Radiant FlightDeck is the operational plane for AI infrastructure, bringing fleet capacity, health, topology, and lifecycle management into one view. Private networking extends that control to how resources connect, enabling administrators to configure networks, manage access, and investigate performance alongside the compute and storage they support. Together, these capabilities create a more consistent foundation for accessing data and running workloads as the cluster evolves.
API-Driven Private Network Provisioning and Management
Every new cluster introduces decisions about connectivity, addressing, and access. FlightDeck brings these into repeatable, API-driven workflows that establish networking alongside the resources it supports.
- Lifecycle control: Create, inspect, update, list, and remove private networks programmatically across CPU, GPU, and storage resources.
- Security operations: Manage security groups through APIs, with defined audit processes to support accountability.
- IP mobility: Move a floating private IP between nodes through an API in under 10 seconds, without requiring an instance reboot.
Protect Workloads with Security Groups and Tenant Isolation
Repeatable provisioning must also preserve clear boundaries. Adding a node or connecting a service should not unintentionally broaden access to the surrounding environment.
FlightDeck enables administrators to manage security groups and review their audit history within network operations. IP- and CIDR-based allow and deny rules govern communication at defined workload, node, service, and network scopes. Administrators can maintain those controls through APIs as deployments evolve.
The underlying fabric enforces tenant separation, with DPU-based controls applying policy at the interface. Infrastructure management interfaces remain separate from tenant-accessible networks. Teams can work with resources belonging to a common cluster while their private networks retain separate addressing, DNS, and access rules.
Within each environment, authorized resources can communicate according to their policies. FlightDeck gives administrators a common place to manage those relationships while preserving the boundaries between private networks.
Movable IPs and Private DNS for Service Continuity
Once connectivity is established, the next challenge is keeping it dependable through maintenance, replacement, and growth.
Private addressing and DNS help separate a service’s identity from the node currently hosting it. Movable private IPs support API-driven reassignment without an instance reboot, reducing the need to reconfigure consumers when a service changes location. Application readiness and state remain part of the recovery process.
Private DNS gives users flexible internal names for storage and other endpoints. Domain-specific forwarding connects node resolvers to customer-designated DNS servers, allowing the cluster to participate in existing enterprise naming arrangements.
By enabling teams to manage these configurations alongside infrastructure changes, FlightDeck helps reduce the amount of change that application teams must absorb. Administrators can manage the environment’s evolution while users retain familiar ways to locate its services.
Virtual Network Peering and Storage Mesh Connectivity
Stable endpoints solve only part of the connectivity problem. The route between resources also determines how effectively applications can use the infrastructure available to them.
Private network peering connects environments without unnecessary traffic detours. Storage mesh connectivity supports communication among authorized storage hosts across subnets, allowing distributed storage systems to exchange data directly.
The distinction matters operationally. Peering connects separate network environments; storage mesh connectivity supports communication within a distributed storage system. Both need to preserve the intended access boundaries while avoiding routing designs that introduce needless contention.
Radiant complements these capabilities with placement informed by physical switch topology and dedicated private connectivity between clusters, storage, and enterprise environments. FlightDeck provides the operational context to manage those connections alongside the resources they serve, helping align logical network configuration and physical traffic paths with workload data needs.
Diagnose Network Issues Faster with Integrated Telemetry
A reachable endpoint can still respond slowly, and a functioning connection can still suffer from dropped traffic or congestion. FlightDeck brings performance evidence and operational context together to support more focused investigation.
- Performance signals: Investigate degraded conditions, errors, drops, utilization, and latency through tenant-visible telemetry.
- Change history: Review network configuration changes and administrative records to understand what changed when an issue emerged.
- Resource context: Examine performance alongside infrastructure health and topology to identify whether a problem follows a resource, path, or configuration.
- Clearer diagnosis: Distinguish connectivity issues from application behavior, reducing uncertainty and improving coordination during troubleshooting.
The Operational Benefits of Private Networking
These capabilities become most valuable when they work together. Provisioning establishes connectivity, policy controls its boundaries, addressing preserves service identity, and telemetry helps teams understand behavior. FlightDeck enables administrators to manage these functions within the wider operation of the cluster. The result is less operational friction between having capacity and using it effectively.
Radiant FlightDeck: Unified Private Network Management
Radiant builds and operates AI infrastructure across data centers, hardware, compute, and managed services. FlightDeck connects these layers through a shared view of resource state, identity, policy, and operational history.
Private networking belongs within that wider picture. A network change affects particular resources, services, and users; understanding those relationships helps administrators act with greater precision. FlightDeck brings that context together with the interfaces needed to configure and operate the networking capabilities supporting the cluster.
The result is more consistent control and infrastructure that is easier to access and integrate as clusters grow, helping turn connected capacity into productive AI.
