Google and AWS split the AI agent stack between control and execution

The era of enterprises stitching together prompt chains and shadow agents is nearing its end as more options for orchestrating complex multi-agent systems emerge. As organizations move AI agents into production, the question remains: "how will we manage them?"

Meanwhile, Google’s Gemini Enterprise adopts a governance-focused approach using a Kubernetes-style control plane. Each method offers a glimpse into how agents move from short-burst task helpers to longer-running entities within a workflow. Upgrades and umbrellas To understand where each company stands, here’s what’s actually new. Google released a new version of Gemini Enterprise, bringing its enterprise AI agent offerings—Gemini Enterprise Platform and Gemini Enterprise Application—under one umbrella.
