The growing adoption of IoT devices, emerging “serverless” architectures hosted in public clouds and the growing dependency on machine-to-machine communication have introduced many changes to modern application architecture. Application programming interfaces (APIs) have emerged as crucial bridges to facilitate communication between different application architectures, helping lead to quicker integration and faster deployment of new services. In addition, DevOps requires end-to-end process automation that often leverages APIs for service provisioning, platform management, and continuous deployment.
