In a microservices architecture, applications are decomposed into multiple smaller services communicating via APIs. This results in:

Increased API traffic due to inter-service communication.

Higher need for governance: enforcing policies, security, throttling, and quotas.

Comprehensive monitoring required to trace calls across multiple distributed services to ensure performance, reliability, and compliance.

SAP Integration Suite’s API Management provides these capabilities:

Traffic management (quotas, rate limiting).

Security policies (OAuth, API keys).

End-to-end monitoring & analytics for distributed calls.

Thus, the correct answer highlights the need for more robust API management and monitoring in high-volume, microservices-driven landscapes.
