What are sandboxes, and why your agents should use them

The document explores the importance of using sandboxes to safely execute agent-generated code within cloud infrastructure, emphasizing the need for isolation boundaries to protect trusted systems. It discusses how sandboxes limit the potential damage from unreviewed or malicious code, which can otherwise lead to data exfiltration, resource exhaustion, or unauthorized access. The text compares different sandboxing mechanisms, such as containers, secure runtimes, and microVMs, highlighting the varying strengths of isolation they offer, with microVMs providing the strongest boundary by using hardware virtualization. Render's infrastructure splits tasks into trusted and untrusted zones, utilizing containers for agent-generated code, and recommends using microVMs for potentially hostile code to better protect the host environment. It outlines strategies for managing resource allocation, task execution, and network egress, focusing on maintaining security by enforcing strict controls over credentials and network access. The document also advises on setting up a sandbox environment using Render's SDK and discusses best practices to avoid common pitfalls, such as over-trusting boundaries or improperly scoping credentials.
