AWS Bedrock
AWS
Managed foundation model platform with Bedrock Agents, AgentCore, and Bedrock Guardrails.
Protocols: MCP, A2A
SDKs: Python, JavaScript, Java, Go, .NET
Docs
Google Vertex AI
Enterprise GenAI platform combining Model Garden, agent tooling, MLOps, and safety controls.
Protocols: MCP, A2A, OpenAPI
SDKs: Python, Java, Go, TypeScript
DocsWarning
Always use Microsoft Foundry as the current name. PromptFlow is being deprecated and Azure ML SDK v1 support ends June 30, 2026.
Google naming caution
Do not confuse Google AI Studio (free playground) with Vertex AI Studio (enterprise). Agentspace is now Gemini Enterprise.
