Cost effective and
Efficient
Continuous Scaling and
Monitoring
Easy to develop
and deploy
 Run code without provisioning or managing servers.
 Pay only for the compute time you consume; No charge when not
running
 Execute for virtually any type of application or backend service
 Simple: Upload your code; Lambda runs & scale code with high
availability.
 Automatically trigger from other AWS services or call directly from
web or mobile app.

23. Amazon API Gateway
Simplified API
development
Performance at Scale Security Controls Monitor & meter
API activity
 Makes it easy for developers to create, publish, maintain, monitor,
and secure APIs at scale.
 With a few clicks, create an API that acts as a “front door” for
applications to access data, business logic
 Tie API functionality to back-end services from Amazon EC2, AWS
Lambda, or any Web app
 Handles traffic management, authorization and access control,
monitoring, and API version managemen for processingconcurrent
API calls
