Building an Amazon Lex Chatbot that engages users in multiple languages

You can create an Amazon Lex Chatbot within a web application to engage your web site visitors. An Amazon Lex Chatbot is functionality that performs on-line chat conversation with users without providing direct contact with a person. For example, the following illustration shows an Amazon Lex Chatbot that engages a user about booking a hotel room.

The Amazon Lex Chatbot created in this AWS tutorial is able to handle multiple languages. For example, a user who speaks French can enter French text and get back a response in French.

Likewise, a user can communicate with the Amazon Lex chatbot in Italian.

This AWS tutorial guides you through creating an Amazon Lex chatbot and integrating it into a Spring Boot web application. The AWS SDK for Java (version 2) is used to invoke these AWS services:

• Amazon Lex
• Amazon Comprehend
• Amazon Translate

Creating AWS video analyzer applications using the AWS SDK for Java

 You can create a Java web application that analyzes videos for label detection by using the Java SDK for Java version 2. The application created in this AWS tutorial lets you upload a video (MP4 file) to an Amazon Simple Storage Service (Amazon S3) bucket. Then the application uses the Amazon Rekognition service to analyze the video. The results are used to populate a data model and then a report is generated and emailed to a specific user by using the Amazon Simple Email Service (SES).

The following illustration shows a report that is generated after the application completes analyzing the video.

In this tutorial, you create a Spring Boot application that invokes various AWS services. The Spring Boot APIs are used to build a model, different views, and a controller. For more information, see Spring Boot.

This application uses the following AWS services:

• Amazon Rekognition
• Amazon S3
• Amazon SES
• AWS Elastic Beanstalk

Using Amazon Cognito to require a user to log into a web application

 Amazon Cognito lets you add user sign-up, sign-in, and access control to your web applications. Amazon Cognito scales to millions of users and supports sign-in with social identity providers, such as Facebook, Google, and enterprise identity providers such as OAuth2. In this tutorial, OAuth2 and Amazon Cognito are used to protect a web application. This means a user has to log into the application by using the credentials of a user defined in an Amazon Cognito User Pool. For example, when a user accesses a web application, they see a web page that lets anonymous users view a log in page, as shown in the following illustration.

When the user clicks the log in button, they are presented with a log in form where they can enter their user credentials.

After the user enters their credentials, they can access the web application.

Creating scheduled events to invoke Lambda functions

You can create a scheduled event that invokes an AWS Lambda function by using an Amazon CloudWatch Event. You can configure a CloudWatch Event to use a cron expression to schedule when a Lambda function is invoked. For example, you can schedule a CloudWatch Event to invoke an AWS Lambda function every weekday. AWS Lambda is a compute service that enables you to run code without provisioning or managing servers.

Note: You can create Lambda functions in various programming languages. For this tutorial, the AWS Lambda function is implemented by using the AWS Lambda Java runtime API.

In this tutorial, you create a Lambda function by using the AWS Lambda Java runtime API. This example invokes different AWS services to perform a specific use case. For example, assume that an organization sends a mobile text message to its employees that congratulates them at the one year anniversary date, as shown in this illustration.

This tutorial shows you how to use Java logic to create a solution that performs this use case. For example, you'll learn how to read an Amazon DynamoDB table to determine which employees have reached the one year anniversary date, how to process the data, and send out a text message all by using an AWS Lambda function. Then you’ll learn how to use a cron expression to invoke the AWS Lambda function every weekday.
