Dynamic scaling with AWS Lambda, Amazon Route 53, and Amazon EC2 Auto Scaling

AWS allows the chaining of features and the ability to incorporate custom serverless functions as a service based on infrastructure events. One such design pattern that has many versatile uses in RTC applications is the combination of automatic scaling lifecycle hooks with Amazon CloudWatch Events, Amazon Route 53, and AWS Lambda functions. AWS Lambda functions can embed any action or logic. The following figure demonstrates how these features chained together can enhance system reliability and scalability with automation.
