Today, we can build and deploy a serverless application in minutes without having to write a line of code using pre-built AWS CloudFormation templates, or services such as the AWS Serverless Application Repository. But can we push the limits even more? In this workshop, we use the Serverless Application Repository combined with Amazon Alexa to create Iron Man's Jarvis look-a-like skill. You learn hands-on with Alexa, Amazon Lex, Amazon SageMaker, and the AWS Serverless Application Repository.

AWS Serverless Application Repository
With serverless your components
are well defined as services.
On the last re:Invent,
AWS Serverless Application
Repository was launched!

If you ever wanted to build a Jarvis how
would you start?

21. © 2018, Amazon Web Services, Inc. or its affiliates. All rights reserved.
Jarvis
Usually people start by building a reciter.
But how do we work on our projects?
One business = application.
Complex business processes are decomposed to simple ones.
Simple business processes are easily converted to serverless components.
We don’t work on apps in a streamlined, but multitasking manner.

How do we build on?

23. © 2018, Amazon Web Services, Inc. or its affiliates. All rights reserved.
Jarvis
We need to find a way how do we translate a simple business process “create
a service to save data to a database” to an AWS Serverless Application
Repository component.
What does a process consist of?
Input, process, output.
Ok, how do we know what’s an input and what’s an output?
We still some help!

Welcome Amazon Comprehend and

How should we do things?
How do we get the sentence?
Alexa Intent Search Query.
How do we analyze the sentence?
Amazon Comprehend Syntax Analysis.
How do we detect what is a process structure?
Get the Subject, Predicate, Object structure.

How should we do things?
How do we get the process?
Convert the structure to an input, process, and output.
How do we know which component based on process?
Search the App Repo for such serverless components.
How do we deploy it and track it?
Deploy the component and store it in the AWS CloudFormation and Amazon
Dynamo DB.

Important note
Serverless Jarvis is still experimental tech
Conversational programming is future, but no one did it yet for production
So have fun, and try to learn something and break things ☺

Summary
• Building your own Serverless Jarvis is not that hard, as we have all the services
in place, what we are doing is just application glue.
• Serverless Jarvis is not that deterministic, but there is a way. (Demo)
• Security is a concern. (How do you know that this component is trustworthy?)
• Is it really the future?
