Ship the right workload to the right runtime

AI Deployment & Hosting

There is no single best host for every AI application. The right choice depends on whether you are serving a frontend, proxying model APIs, running background agents, storing state, or hosting the model itself. Start with the workload and its failure modes, then compare platforms.

Decisions this guide helps you make

Whether the workload needs a GPU or only calls an external model API.
Whether requests stream, run in the background, or need persistent connections.
How much infrastructure control the team can operate safely.
What the full cost looks like after databases, egress, storage, and idle capacity.

01

Choose by workload—not by logo

A static AI frontend, a streaming API, a background agent, and a GPU model server need different infrastructure.

Best hosting for AI applications

Compare serverless, PaaS, managed servers, VPS, and GPU providers by workload.

Vercel vs Railway vs Fly.io

Pick a runtime for frontends, APIs, workers, containers, and globally distributed services.

Best cloud GPU providers

Compare GPU availability, pricing models, storage, and operational control.

02

Deploy managed AI backends

Managed platforms reduce operational work, but their limits still determine which AI workloads fit.

Cloudways for AI applications

An honest look at managed servers for APIs, RAG backends, and CPU-based workers.

Deploy an AI app on Railway

Ship an application, worker, and database without maintaining a server.

Deploy an AI app on Cloudways

Configure a managed server for a Python or Node AI backend.

03

Design around platform limits

Streaming model calls and durable background work need different execution paths. Treat proxy and serverless deadlines as architecture boundaries.

Long AI requests on Vercel

Choose streaming, jobs, queues, polling, or a separate worker runtime.

AWS Lambda timeouts for AI workloads

Move inference and batch work into bounded asynchronous patterns.

Diagnose first-token latency, proxy buffering, and long-running requests.

AWS vs Google Cloud vs Azure

Compare managed AI, GPU, serverless, identity, data, and enterprise requirements.

04

Self-host models deliberately

Self-hosting trades API dependence for capacity planning, model operations, and hardware responsibility.

Best hosting for Ollama in production

Understand when Ollama belongs on a VPS, dedicated server, or GPU instance.

A practical path from an empty GPU server to a reachable model endpoint.

AI deployment checklist

Validate secrets, health checks, persistence, budgets, and rollback.

Linux for AI servers

Prepare GPU drivers, model storage, containers, permissions, services, and monitoring.

SSH for GPU machines

Use keys, bastions, host verification, and narrow automation identities.
