Amazon, Microsoft, and Google are converging on the same enterprise agent architecture
Analysis by Janakiram MSV (The New Stack, July 20, 2026) of the **architectural convergence** of the three hyperscalers' enterprise agent platforms: in nine months, **Amazon Bedrock AgentCore**, **Microsoft Foundry**, and **Gemini Enterprise Agent Platform** have converged on the **same six primitives** — runtime, memory, tool gateway, identity, observability, governance — under different brand names. What was a fragmented collection of libraries 18 months ago is becoming a distinct **platform layer**. The thesis: this convergence replays the **2011-2016 PaaS inflection**, where **Cloud Foundry** and **Heroku** unified VMs, load balancers, queues, and secret stores around a portable **application contract** — except that here **no equivalent contract yet exists**, and **no open source project has claimed it**. Consequence: an enterprise cannot **move an agent from one cloud to another** (session state, traces, and identity all end up with a single provider; migrating means rebuilding everything). The author proposes a **line-by-line mapping** of the Cloud Foundry contract onto agents, sets out three design principles (package the agent as **one deployable unit**, **attach** capabilities rather than embedding providers, integrate the **operational** layer into the abstraction), points to what open protocols (MCP, A2A, OpenTelemetry) leave out of scope — the **lifecycle** — and delivers three due diligence questions: **governance** (neutral foundation vs. vendor), **packaging** (the same artifact on two clouds without rewriting), **state** (exportable memory). Verdict: whoever ends up owning the **agent control plane** will define *what an agent is*.
