Amazon Lex is an AWS service that helps in building an interface where applications use text and voice. Alexa from Amazon also uses Amazon Lex as a backend engine.

“A chatbot is a computer program that connects with the user in a natural language using audio or text mode. It understands what the user says and respond based on a series of rules”.
Intent means a task end-user wants to achieve. Bot can support multiple intents, like flight booking, taxi booking, check price or gold or even start-stop an ec2 instance.
For each intent, you provide the following required information:
Intent can have zero or more slots. You can add slots while configuring an intent configuration. When a bot is called Amazon Lex asks the user for the defined slot values. Amazon Lex asks the user all the slot values before fulfilling the tasks asked by the end-user.
For example, the startec2instance or stopec2instance intent will need slots such as instance name, instance-id, zone-name, etc. In the intent configuration, we can add slots. For each slot, we ask for a slot type and a message for Amazon Lex to ask to the user. Users can answer with a slot value that may have some extra words like “start the ec2 instance with instance id XXX please” or “can we stop and instance by name XXX”. Amazon Lex can still perform the tasks.
Slots have a type. We can create our custom slot types or use built-in slot types. For example, we can have the following slot types for startec2instance intent:
