My team and I have played around Lambda in different aspect, such as CI/CD pipeline (CodeCommit/CloudFoamtion), image processing and database query. Lambda has the form of water, which can penetrate to every corner of AWS services, great integrated with other services. And the event driven design by event source object. I would say is a masterpiece of cloud services. Lambda Lambda is an effortless operational paradise, I just focus on Nodejs development without worrying about deployment, logs, public URL configuration. Why Lambda — Perfect integration with powerful AWS services — and It helps to implement an production API with public URL, just within few clicks. API Gateway Lambda. — It is completely , it will only run when invoked. This is perfect for application services having quiet periods followed by peaks in traffic. Also this advantage helps and it is 100% no operations event driven — , Lambda can instantly scale up to a large number of parallel executions, for which the limit is controlled by the . Downscaling is handled simply by automatically terminating the Lambda function execution when do code finishes running. Scalability Number of concurrent requests Reference: — https://www.contino.io/insights/5-killer-use-cases-for-aws-lambda
