| Best for | Large organizations already running on Microsoft 365, Teams, SharePoint, and Dynamics. | Engineering teams on Google Cloud who want to build agents using Gemini's long-context capabilities and integrate directly with BigQuery, Cloud Storage, and Google Workspace. |
| Not for | Companies not primarily on the Microsoft stack. The integration depth is Microsoft-native; the rest of the ecosystem is an afterthought. | Teams not on Google Cloud — Vertex's value proposition is integration depth that doesn't transfer.
