AWS Lambda

Overview

Run code without thinking about servers.Pay for only the compute time you consume.

AWS Lambda lets you run code without provisioning or managing servers. You pay only for the compute time you consume - there is no charge when your code is not running. With Lambda, you can run code for virtually any type of application or backend service - all with zero administration. Just upload your code and Lambda takes care of everything required to run and scale your code with high availability. You can set up your code to automatically trigger from other AWS services or call it directly from any web or mobile app.

Features of AWS Lambda

No Servers to Manage - AWS Lambda automatically runs your code without requiring you to provision or manage servers. Just write the code and upload it to Lambda.

Continuous Scaling - AWS Lambda automatically scales your application by running code in response to each trigger. Your code runs in parallel and processes each trigger individually, scaling precisely with the size of the workload.

Subsecond Metering - With AWS Lambda, you are charged for every 100ms your code executes and the number of times your code is triggered. You don't pay anything when your code isn't running.

What can I build with AWS Lambda?

Data Processing - You can use AWS Lambda to execute code in response to triggers such as changes in data, shifts in system state, or actions by users. Lambda can be directly triggered by AWS services such as S3, DynamoDB, Kinesis, SNS, and CloudWatch allowing you to build a variety of real-time serverless data processing systems.

Real-time File Processing - You 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.

Real-time Stream Processing - Whether you’re storing pharmaceutical or financial data, or multimedia files such as photos and videos, Amazon S3 can be used as your big data object store. Amazon Web Services offers a comprehensive portfolio of services to help you manage big data by reducing costs, scaling to meet demand, and increasing the speed of innovation.

Extract, Transform, Load - You can 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.

IoT Backends - You can build backends using AWS Lambda and Amazon Kinesis for Internet of Things (IoT) device data telemetry and analysis.

Mobile Backends - You can build backends using AWS Lambda and Amazon API Gateway to authenticate and process API requests. Lambda makes it easy to create rich, personalised app experiences.

Web Applications - 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.
