When those black boxes malfunction, drift, or change, you are at the mercy of AWS’s release cadence and operational practices. You will still need teams who understand the behavior of your agents in detail, but you will be diagnosing problems in systems whose core behavior is defined by a vendor’s code and policies, not your own. That is a different kind of fragility. Instead of owning complexity you can see and manage, you’re renting complexity and hoping it behaves.
On top of that, operations teams now have to understand not only distributed cloud-native systems, but emergent, probabilistic agent behavior embedded within them. If your observability, governance, and control mechanisms are all bound to AWS-specific services, you lose the ability to build a unified operations view across clouds and on-prem systems. AWS wants to be your single pane of glass, but the reality is that most large enterprises need several panes, and those panes must interoperate.
Taking the long view
When you adopt Nova 2 and its ecosystem as your primary agentic platform, you are choosing a vertically integrated stack. The immediate upsides are undeniable: optimized performance, deep integrations, turnkey security patterns, and less glue code. For many teams, particularly those that are small, under-resourced, or deeply aligned with AWS already, this is a rational short-term decision.
