AWS Lambda is an event-driven, serverless computing platform provided by Amazon as a part of the Amazon Web Services that runs code in response to events and automatically manages the compute resources required by that code without provisioning or managing servers. AWS Lambda can automatically run code in response to multiple events. Lambda can be directly triggered by AWS services such as S3, DynamoDB, Kinesis, SNS, and CloudWatch or changes in data, shifts in system state, or actions by users.AWS Lambda offers to extend other AWS services with custom logic, create your own back-end services that operate at AWS scale, runs code on high-availability compute infrastructure and performs all the administration of the compute resources, including server and operating system maintenance, and code monitoring and logging, serverless backends using AWS Lambda and Amazon Kinesis to handle web, mobile, Internet of Things (IoT) device data telemetry, and 3rd party API requests using Amazon API Gateway, calling it directly from any web or mobile app, thumbnail images, index files, process logs, aggregate and filter data in real-time, application activity tracking, transaction order processing, click stream analysis, data cleansing, metrics generation, log filtering, indexing, social media analysis, Messages arriving in an Amazon Kinesis stream, AWS API call logs created by AWS CloudTrail, built-in logging and monitoring through CloudWatch.
