API management from a network engineer's perspective focuses on security, performance, reliability, and automation. Key capabilities include multi-layer security using tools like Cloud Armor, IAM, and VPC service controls; AI and machine learning to identify anomalies, predict traffic, and ensure compliance; global reach and high performance using Cloud CDN; and a hybrid multi-cloud architecture with private network peering between VPCs for low latency and separation of customer and Apigee networks.
