Serverless - Interacting with DynamoDB using Lambda

Overview

To continue learning about serverless services on AWS, we will build a web application for managing documents (Document Management System). The application allows users to upload multiple documents at once, view details, download and delete documents, and search for documents. In addition, users can view overview information such as the number of files, total uploaded size, and account information. Below is the complete workshop series:

• Introduce Document Management System - Write Lambda functions
• Use Amplify Authentication and Storage
• Deploy front-end and API
• Deploy application with AWS SAM
• Set up CDN and SSL
• Build the searching feature
• Deploy CI/CD with CodePipeline
• Trace and monitor with X-Ray and CloudWatch

Below is the architecture of the application:

• Create tables in DynamoDB to store file information
• Use AWS Amplify to create storage for managing files and Amazon Cognito User Pool to manage users
• Deploy SSL/TLS for the application using AWS Certificate Manager, Route 53, and CloudFront.
• Search documents by name, file type, or tag with DynamoDB Streams and AWS OpenSearch.
• Build CI/CD with CodePipeline
• Track and monitor the application with X-Ray and CloudWatch

In this workshop, we will create Lambda functions to read, query, and delete data in DynamoDB.
