Amazon Lex leverages the functionalities of AWS Lambda to implement business logic in bots. Furthermore, developers can also build enterprise productivity bots that offer a conversational interface for various business functions, such as accounts, sales, and human resources. The designed bots can be deployed over various channels, such as the AWS Mobile Hub, Facebook, Slack, Twilio, AWS Lambda, and Amazon CloudWatch. Amazon Lex allows developers or enterprise customers to design and build bots very easily without any knowledge about machine learning or deep learning. For example, developers have to define a basic conversational flow in the Lex console and the remaining work, such as the intent of users and dialogue management, are managed by Amazon Lex.
