by Kashif Imran, Sr. Solutions Architect, AWS In this workshop you'll learn to build a web application using a serverless architecture. With fresh funding from its seed investors, Wild Rydes (www.wildrydes.com) is seeking to build the world’s greatest mobile/VR/AR unicorn transportation system. The scrappy startup needs a first-class webpage to begin marketing to new users and to begin its plans for global domination. Join us to help Wild Rydes build a website using a serverless architecture. You’ll build a scalable website using services like AWS Lambda, Amazon API Gateway, Amazon DynamoDB, Amazon Cognito, and Amazon S3.

AWS Lambda: Serverless computing
• Run code without servers. Pay only for the compute time you consume.
• Triggered by events or called from APIs:
– PUT to an Amazon S3 bucket
– Updates to Amazon DynamoDB table
– Call to an Amazon API Gateway endpoint
– Mobile app back-end call
– And many more…
• Makes it easy to:
– Perform real-time data processing
– Build scalable back-end services
– Glue and choreograph systems

Benefits of AWS Lambda
No Servers to Manage Continuous Scaling Don’t Pay for Idle Capacity
Lambda allows you to run
application logic without
provisioning servers or worrying
about the health or security of
underlying resources
Lambda scales infrastructure
beneath your application logic;
just send requests and events
and Lambda will automatically
scale to accommodate it
With Lambda, you’re billed in
100ms increments of execution
time and number of requests
and you’re never charged for
anything when your code isn’t
running

Amazon DynamoDB
• Fast and flexible NoSQL database service
for any scale
Dead Simple
• GetItem(primaryKey)
• PutItem(item)
Robust Depth
• Fine-Grained Access Control
• Streams
• Triggers
• Cross-Region Replication
• DynamoDB local
• Free-text search
• Titan Graph Database integration
• Strong consistency option
• Atomic counters

Amazon API Gateway
• Create, publish, maintain, monitor, and secure APIs at any scale
Create a unified API
frontend for multiple
backend microservices
DDoS and throttling to
protect your backend
microservices
Authenticate and authorize
requests to your backend
microservices

Amazon Cognito
• Add user sign-up, sign-in, and data synchronization to your apps
Add user sign-up and sign-
in to your mobile and web
apps
Federate identities and
provide secure access to
AWS resources
Store and sync across
devices
