What You’ll Get Out of This Session

• What AWS offers for mobile application development

• Easier to architect your mobile application

• Write cross platform mobile applications with AWS services

We asked two questions to our mobile customers:

What makes your mobile apps unique?

Where are you spending most of your time?

Amazon Mobile Analytics

Scalable and Generous

Free Tier

Focus on metrics that

matter. Usage reports

available within 60

minutes of receiving data

from an app

Fast

Scale to billions of

events per day from

millions of users.

Own Your Data

“Easily collect, visualize and understand your app usage data at scale”

Data collected are not

shared, aggregated, or

reused

Key Business Metrics

(with one line of code)

1. Monthly Active Users

(MAU)

2. Daily Active Users

(DAU)

3. New Users,

4. Daily Sessions,

5. Sticky Factor,

6. 1-Day Retention,

7. Avg. Revenue per DAU,

8. Daily Paying Users,

9. Avg. Paying DAU

Track Retention

User retention is a key

indicator to judge the

outcome of a marketing

campaign, new feature

introduction, UX changes,

app updates, etc.

Mobile Analytics provide four

charts to track daily or

weekly rate of returning

users, after first use of the

app

Get behavioral insights into app specific

actions that your users take

Reports provide a view of how often custom

events occur. You can add further context

with Attributes and Metrics, to each custom

event

Examples

Track the number of

Likes/Shares, per

article, in a news app

Understand player

abort rates per

level, in a game

Number of songs

played, per user

session, in a music

app

In-app item popularity

in a shopping app

Auto Scaling

(Never under or over

Focus on business logic,

your code; AWS Lambda

handles everything else

Zero Administration

Lambda scales the

infrastructure as needed

to match the event rate

and pay as you go

servers to manage”

Send Push Notifications: Amazon SNS Mobile Push

What Customers Told Us About “Push Notifications”

Sending large-scale push notifications, cross-platform is still hard.

Developers want to be able to reach their customers globally and

across all devices.

Each platform works differently, and push gets even more

complex as you scale to support millions of devices.

Amazon DynamoDB Connector: Object Mapper

Simplifies access to Amazon

DynamoDB in you app

Map client-side classes to Amazon

DynamoDB tables

Removes the need to transform

objects into tables and vice versa

Amazon DynamoDB: Example @DynamoDBTable(tableName = "Bookstore")

public static class Book {

private int id;

private String isbn, title;

private Boolean hardCover;

@DynamoDBHashKey(attributeName = "id")

public int getId() {

return id;

}

public void setId(int id) {

this.id = id;

}

@DynamoDBAttribute(attributeName="isbn")

public String getIsbn() {

return isbn;

}

...

}

Id isbn Title hardCover

1 22-22222 My First Book Yes

2 43-43234 My Favorite Book No

3 55-12345 My New Book Yes

Table: Bookstore

Amazon DynamoDB: Example// Build a book object

Book book = new Book();

book.setId(17);

book.setIsbn("222-2222222222");

book.setTitle("Some Title");

book.setHardCover(true);

// Save book object to dynmaoDB

mapper.save(book);

// Update item and save object again

book.setTitle("Updated Title");

book.setHardCover(false);

mapper.save(book);

// Load another book

Book anotherBook = mapper.load(Book.class,7);
