Getting a model to answer 10 inference requests concurrently is tricky but simple enough; getting it to handle 2,000 engineers hitting a coding assistant with long contexts, all day, without runaway costs, is where teams stall. A working endpoint is only the beginning. Teams need to identify the supporting hardware and wire up the right components—serving, scaling, observability, and cost guardrails—so the deployment can support expected SLAs and SLOs under real, sustained load.

DigitalOcean already offers Serverless Inference on the DigitalOcean AI Platform : a fast path to models from OpenAI, Anthropic, Meta, or other providers, with minimal setup and token-based pricing. This offering works well for many use cases. However, when you need your own weights, predictable performance on dedicated GPUs, and economics that favor sustained, high-volume token generation over pay-per-token bursts, a different approach makes sense

Dedicated Inference , our managed LLM hosting service on the DigitalOcean AI Platform, fills that gap.

Dedicated Inference deploys and operates an opinionated inference stack on dedicated GPUs, with Kubernetes-native orchestration under the hood. You interact through the control plane and APIs you already use in the DigitalOcean ecosystem; the data plane exposes public and private endpoints so applications inside, or outside, your VPC can call your models securely.

The service is designed to collapse a vast combinatorial space—GPU SKUs, runtimes, routers, autoscaling policies—into guided defaults so teams hit production milestones faster than DIY stacks, while retaining knobs that matter for model serving: replicas, scaling behavior, and advanced optimizations as you roll out your product roadmap.

What we manage vs. what you control

Every managed product draws a line between operator-owned and customer-owned concerns. Dedicated Inference aims to put day-two operations—cluster lifecycle integration, ingress, core serving and routing components, and the glue between them—on the platform side, while leaving model choice, capacity, and workload-specific tuning with you.

Typically platform-managed :

Provisioning and lifecycle of the underlying orchestration footprint in line with product design (for example, managed Kubernetes integration and GPU pool coordination).

Core inference engine and orchestration integration, including patterns that matter at scale: intelligent routing, autoscaling hooks, and production-oriented serving paths.

Endpoint creation, health and scaling workflows, and the operational automation required to keep endpoints aligned with declared configuration.

In your hands :

Selecting models (including bring-your-own-model paths where supported), GPU profiles, and replica counts appropriate to your SLOs and budget.

Configuring scaling behavior and, over time, advanced serving options that map to your latency, throughput, and cost goals.

Connecting applications via stable HTTP APIs consistent with common LLM client stacks.

Dedicated Inference overview

Dedicated Inference builds on industry-standard building blocks so customers benefit from community momentum and continuous improvement:

vLLM as a capable, widely adopted inference engine for large language models on modern GPUs.

LLM-d as a Kubernetes-oriented stack for distributed inference patterns—precise prefix- cache aware routing, scaling concerns that differ from traditional HTTP services, and room to grow into more advanced topologies as workloads demand.

This combination reflects a deliberate choice: meet customers where they are today (OpenAI-compatible APIs, familiar GPU offerings on DigitalOcean) while staying aligned with where the ecosystem is moving on routing, replication, and scale-out inference.

For readers who want more depth on why LLM routing differs from classic load balancing—and how prefix cache awareness changes the game—see our article on Load Balancing and Scaling LLM Serving .

High-level architecture

The system design separates a control plane (how endpoints are created, updated, listed, and deleted) from a data plane (how chat/completions request traffic reaches your models). That mirrors the management requests, which take a path built for regional placement and durable lifecycle work. Inference requests take a direct, low-latency path in front of your GPUs.

Control plane: central entry, regional execution

What does “control plane” mean here? In this split, the control plane is everything that handles management traffic: management rpc for Dedicated Inference endpoints, plus the durable bookkeeping that turns your declared intent into running DI infrastructure. It is separate from the data plane, which is the hot path for inference (chat/completions-style) requests once an endpoint is healthy.

Central API layer : Requests originating from the DigitalOcean Cloud UI, automation workflows, or the public API are routed through a centralized API layer first. This layer maintains the mapping of endpoint ownership by region and transparently forwards each request to the appropriate regional backend. This design follows a multi-region fan-out model, where regional endpoints are addressed using stable identifiers.

Regional Dedicated Inference service : Each region operates a control-plane service responsible for the full lifecycle management of instances within its scope. This includes persisting the desired state, reconciling it with the observed state, advancing lifecycle status (e.g., creating → active), and enqueuing the workflows that provision or mutate the underlying infrastructure. In this context, lifecycle refers to the state machine governing transitions from requested to running and reachable. An instance represents the managed inference deployment as a whole—encompassing both its control-plane record and the associated backing resources.

Separate worker-style components perform integrations that need retries, backoff, and idempotency—calling the Kubernetes API, watching object status, and publishing lifecycle updates back to the core service. This is similar to the reconciler pattern familiar from Kubernetes operators: observe desired state, act, repeat until reality…
