Azure Container Apps Sandboxes: Secure AI Code Execution

Microsoft has announced the public preview of Azure Container Apps Sandboxes. This new feature allows users to run untrusted code from AI agents in secure, hardware-isolated environments. Here's the thing: each sandbox starts from an OCI disk image in less than a second and can scale to thousands of instances. What's interesting is that it incurs no cost when idle, making it ideal for short, bursty tasks typical of agentic workloads. This helps prevent security risks, as an agent's generated code is isolated from the host environment. Without this hard boundary, a capable model could be vulnerable to prompt injection attacks. The bottom line: developers can now safely execute untrusted code without needing to build custom isolation setups, saving significant operational investment.
