What is sandbox infrastructure? A guide for AI and engineering teams

Sandbox infrastructure comprises a comprehensive stack of systems that facilitate the safe execution of isolated workloads in production environments. It includes elements such as isolation technology, orchestration, networking, secrets management, observability, and lifecycle management. These components work together to create secure boundaries, manage workloads efficiently, and maintain operational integrity without risking production systems. Different isolation models, such as containers, gVisor, and microVMs like Firecracker and Kata Containers, provide varying levels of security, with microVMs offering the highest security for untrusted code by utilizing dedicated guest kernels. Platforms like Northflank provide ready-to-use sandbox infrastructure that integrates all necessary components, allowing teams to focus on product development rather than building infrastructure from scratch. This infrastructure supports a range of use cases, from AI coding agents and code interpreters to reinforcement learning pipelines, and can be deployed in public or private cloud environments, offering flexibility and scalability for diverse workloads.
