Major chat platforms, such as Facebook Messenger, have recently added support for chatbots, thus making chatbots more accessible for the end users. This paper presents a case study on building and designing a Messenger chatbot for a media company. The chatbot uses a Serverless Microservice architecture which was implemented using Amazon Web Services (AWS) including API Gateway, Lambda, DynamoDB, SNS and CloudWatch. The paper presents the architecture and reports the findings regarding the design and the final implementation. These findings are also compared to other recent studies around the same emerging topic.
