How do you manage API calls between cloud services in hybrid cloud systems?

Hybrid cloud systems integrate public and private cloud resources, and managing API calls between services is crucial. It ensures efficient cross-cloud interoperability, security, and elasticity, applied in integration scenarios such as data synchronization and load balancing.

Core components include an API gateway (e.g., Apigee) as a unified entry point, and a service mesh to handle microservice communication. Features涵盖身份验证 (OAuth), monitoring, and logging. In practical applications, it enhances reliability, reduces latency, simplifies multi-cloud workflows, and improves system performance and compliance.

Implementation steps: Deploy API management tools; configure security mechanisms (e.g., API key policies); set up monitoring and logging systems. Typical scenarios include cross-cloud storage access, and the business value lies in optimizing costs, improving resilience, and reducing risks.
