Best runtime platforms for AI applications and production infrastructure

AI runtime platforms provide the production infrastructure for capabilities such as model inference, GPU compute, isolated agent or code execution, application hosting, databases, storage, CI/CD, security, and observability, with the appropriate choice depending on how much of this stack an organization needs managed. Northflank is positioned as a broad, full-stack option combining GPU workloads, microVM-backed sandboxes, application deployment, databases, CI/CD, and infrastructure control, including bring-your-own-cloud deployment, while Modal focuses on serverless GPU compute, training, inference, batch work, and sandboxes. E2B specializes in secure isolated environments for AI-generated or untrusted code, Amazon Bedrock AgentCore offers an AWS-integrated managed runtime for AI agents, and Replicate and Together AI provide managed model inference, particularly for custom and open-source models. The comparison emphasizes that specialized services can simplify individual functions, but using several platforms can increase integration and operational complexity, whereas broader platforms may suit teams building complete production AI systems.
