Key benefits:

Free and Open Source Software (OSS) - zero license costs

Optional enterprise support available for organizations requiring SLAs

Zero-configuration service discovery reduces operational overhead

Real-time traffic routing adjustments based on service health

Phase 2: API/AI Gateway - Securing and Controlling Access

When you need it:

Centralized authentication and authorization requirements

API access management across multiple teams/departments

Content Guard for bidirectional safeguards

Phase 3: API Management - Full Lifecycle Runtime Governance

Key benefits:

Premium API Management tier for full lifecycle management

Comprehensive API governance with policy enforcement

Developer self-service through customizable portals

End-to-end observability for operations and business analysis
