What You Will Learn in this Session • Some key facts for architecting a mobile backend • Building a sample application – live demo – Intro to the sample application – Live building/deploying/configuring the blocks step by step
Key Facts for Architecting a Mobile Backend Mobile applications are customer facing applications • Number of clients can be huge • If customers use your app 24/7 then you must run and support it 24/7 • Scaling is hard – think about traffic spikes • Some code might run on the client side
How you can use AWS • Use AWS building blocks for your architecture • Mobile applications can directly interact with AWS services • Use AWS managed as much as possible – and let us do the heavy lifting
Demo Use Case • Users can pin messages with pictures to POIs around their current location • Read all messages around your current location like a twitter feed • Messages are location specific and not user specific
Demo Application Overview • Mobile JavaScript application • Use AWS building blocks as much as possible • Use AWS shared infrastructure as much as possible
Demo Architecture Walkthrough
Step 1
Provide application + config (html/js/pictures)
Step 2
Add a friendly DNS name
Step 3
Read POIs next to your location and show them on a map
Step 4
Read messages from Amazon DynamoDB. Messages are pinned to a POI retrieved from Amazon CloudSearch and ordered by date.
Step 5
Add a login with AWS IAM Web Identity Federation to get temporary access keys/secrets.
Step 6
Write messages into an Amazon SQS queue.
Step 7
An AWS Elastic Beanstalk application consumes messages from SQS and writes them to DynamoDB.
Step 8
Upload images for the messages to Amazon S3

What to change if I would have a few minutes more
• Filter the messages for inappropriate content • Add scaling automation to Amazon DynamoDB with the “Dynamic DynamoDB” library • Prevent Amazon DynamoDB Hot Keys with spreading the POIs over several HashKeys
