The Sandbox Solution: Closing The AI Testing Gap
Cloud Native Now, Tuesday, March 31st, 2026
Testing AI agents against real cloud infrastructure is expensive, slow and often unreliable. In this interview from KubeCon Europe, Mike Vizard speaks with Waldemar Hummer, CEO of LocalStack, about how high-fidelity sandboxes are helping development teams close the gap between writing AI-driven applications and validating that they actually work as intended.
Hummer explains the core problem: AI agents that interact with cloud services need to be tested in environments that behave like the real thing, but spinning up actual AWS or cloud resources for every test cycle creates waste, drives up costs and introduces unpredictable delays. LocalStack addresses this by providing a local emulation layer that replicates cloud service behavior closely enough for developers and AI agents to run meaningful tests without ever touching a production environment.
