AWS Lambda

Lambda – server less application – lets you run code without provisioning or managing servers.  You only pay for the compute time you consume – no charge when your code is not running.

No provisioning of servers
Compute services where you upload your code and create a Lambda function
Valid triggers – every time user sends a request to API Gateway it generates a Lambda function.  First 1 million requests are free.  $.20 per 1 million after.
Lambda scales out not up automatically
Lambda functions are independent 1 event = 1 function
Server less services – API Gateway, S3, dynamoDB, AWS IOT, Alexa Skills kit, Alexa Smart Home, CloudFront, Cloudwatch events, cloudwatch logs, CodeCommit, Cognito, Kinesis, SNS.
