AWS Lambda

AWS Lambda lets developers to run codes without provisioning or managing servers. With Lambda, users can run code for virtually any type of application or backend service - all with zero administration. All they need is to upload their code and Lambda takes care of everything required to run and scale their code with high availability.A developer can set up their code to automatically trigger from other AWS services or call it directly from any web or mobile app.AWS Lambda automatically scales applications by running code in response to each trigger. Codes run in parallel and processes each trigger individually, scaling precisely with the size of the workload.With AWS Lambda, users are charged for every 100ms their code executes and the number of times their code is triggered. A user does not pay anything when their code isn't running.Enterprises can also use AWS Lambda to perform data validation, filtering, sorting, or other transformations for every data change in a DynamoDB table and load the transformed data to another data store.

Moreover, users can use AWS Lambda and Amazon Kinesis to process real-time streaming data for application activity tracking, transaction order processing, click stream analysis, data cleansing, metrics generation, log filtering, indexing, social media analysis, and IoT device data telemetry and metering.The software allows developers to build serverless backends using AWS Lambda to handle web, mobile, Internet of Things (IoT), and 3rd party API requests.
By combining AWS Lambda with other AWS services, developers can build powerful web applications that automatically scale up and down and run in a highly available configuration across multiple data centers – with zero administrative effort required for scalability, back-ups or multi-data center redundancy.
