Enterprise Agent Architecture 2026
Reference architectures for governing multi-vendor AI agents. Three patterns. One governance layer.
The Governance Layer Architecture
JieGou sits above vendor-specific agent platforms, providing unified governance, memory, and compliance across all of them.

MCP + A2AThree Reference Architecture Patterns
Choose the pattern that matches your vendor landscape. All three use JieGou as the governance layer.
Architecture 1: Salesforce-Centric
Agentforce handles Sales, Service, and Marketing automation. JieGou governs the other 12 departments and provides cross-department memory, unified audit trail, and consistent approval policies.
Architecture 2: Microsoft-Centric
Copilot Studio manages Office-centric workflows and IT helpdesk. JieGou provides governance across non-Office departments, bridges MCP tools with A2A agent coordination, and adds department-specific automation.
Architecture 3: Multi-Vendor
Agentforce + Copilot Studio + Vertex AI + ServiceNow + custom agents, all governed by JieGou. Unified audit trail, cross-vendor memory, consistent compliance policies, and a single governance dashboard for all agents.
Protocol Mapping: Which Vendor Uses What
How JieGou bridges each vendor's protocol into a unified governance layer.
| Vendor | Primary Protocol | JieGou Bridge |
|---|---|---|
| Salesforce Agentforce | A2A | JieGou acts as A2A consumer and registry |
| Microsoft Copilot Studio | MCP | JieGou hosts 245 certified MCP servers |
| Google Vertex AI | A2A | JieGou acts as A2A host and consumer |
| ServiceNow | A2A | JieGou integrates via A2A registry |
| Custom Agents | MCP + A2A | Full dual-protocol support |
Build vs. Buy: Cross-Vendor Governance
Why a dedicated governance layer is more cost-effective than building cross-vendor governance in-house.
| Dimension | Build In-House | Buy (JieGou) |
|---|---|---|
| Time to Deploy | 6-12 months for cross-vendor governance framework | Days to weeks with pre-built governance layers |
| Protocol Support | Custom MCP/A2A implementation per vendor | 245 certified MCP servers + full A2A support |
| Ongoing Maintenance | Dedicated team for protocol updates and vendor changes | Managed platform with automatic updates |
| Compliance | Custom audit trail, RBAC, and approval logic | 10-layer governance with SOC 2, HIPAA, GDPR support |
