AWS Lambda is an event-driven, serverless computing platform provided by Amazon as a part of the Amazon Web Services. It is a compute service that runs code in response to events and automatically manages the compute resources required by that code. AWS Lambda executes your code only when needed and scales automatically, All you need to do is supply your code in one of the languages that AWS Lambda supports (currently Node.js, Java, C#, and Python).
AWS Dynamo DB is a fully managed NoSQL database service that provides fast and predictable performance with seamless scalability.AWSDynamoDB lets you offload the administrative burdens of operating and scaling a distributed database so that you don't have to worry about hardware provisioning, setup, and configuration, replication, software patching, or cluster scaling.
Here in this documentation, I am going to provide a detailed explanation and step by step process of triggering AWS Lambda function to work with AWS Dynamo DB.
Create a Lambda function to process data to AWS Dynamo DB. Test the Lambda function by triggering it manually and checking the AWS Dynamo DB tables for the correctness of data insertion and deletion, using the AWS Management Console.
Create a Lambda Function and Invoke it Manually (Using the AWS Console)
