I see the pattern repeated across industries. Organizations design resilience for their traditional applications, then deploy AI on top without asking whether the same guarantees hold. In one global financial services firm I advise, a real-time credit-decisioning model running on a single cloud region took a 47-minute outage during a regional availability event. The halted loan approvals cost more than the system’s entire annual infrastructure budget, and the resilience rework that followed cost several times what designing it in from the start would have. The leaders who avoid this should ask four questions before go-live:

  1. What happens when the network fails?
  2. What happens when the model degrades?
  3. What happens when an agent executes only halfway?
  4. Who holds the authority to halt and audit?

What the cloud providers signaled this spring

The major providers are on track to spend close to $700 billion on AI infrastructure in 2026, roughly three and a half times the 2024 level. Their announcements are strategic signals, not just features. Last year they converged on one message: enterprises cannot run everything in public cloud, so all three built ways to bring their infrastructure into your data center and your sovereign environment. This year the signal advanced a step. They stopped talking about where workloads run and started shipping the layer that governs what agents are allowed to do: identity, containment, auditability and rollback.

Microsoft introduced an “Agent Computer” model with execution containers and machine identity for agents. AWS built Amazon Bedrock AgentCore around runtime, memory, identity and auditability. Google shipped an agent gateway and sovereign controls for cross-cloud traffic. As Bain observed, agentic AI is now an economics and operations problem, not just a capability problem. The through-line, captured by Microsoft’s own framing, is that AI alone will not change your business; the system running it will. McKinsey’s read is consistent: workloads are becoming more distributed, specialized and operationally demanding, which forces more deliberate infrastructure decisions.
