AWS Certified Data Analytics Specialty 2021 – Hands-On - Lambda Integration - Part 1

AWS Lambda is a serverless computing service that allows you to run code without managing servers. It offers cost efficiency by charging only for the compute time you use. Lambda supports various programming languages and can be used for real-time file processing, stream processing, and as a Kron replacement. It integrates with many AWS services like S3, Kinesis, and DynamoDB, enabling event-driven data processing. Lambda's flexibility allows it to interact with external services and perform complex data transformations.
