Architecture
Now we will try to draw the architecture diagram for this application:
The previous diagram shows how the overall application functionality would look. The
working of the application is explained in the following points:
• The clients sends requests to the application deployed on Tomcat or any other serv-
er.
• The code written for the application connects with DynamoDB to perform the op-
eration. Sample operations would include adding a new question, adding a reply to
an already existing question, deleting a topic/question, and so on.
• AWS S3 can be used to archive the data from DynamoDB; we have seen how to
archive data on S3 using EMR in Chapter 6 , Integrating DynamoDB with Other
AWS Components .
