Concrete Software builds cross platform mobile games

Concrete Software has been making hit mobile games

like Jellyflop and PBA Bowling Challenge since 2003.

With Amazon Cognito, We

can build games much faster

and provide great user

experience to our customers.

Keith A. Pichelman

CEO, Concrete Software

”

“• Provide a seamless user experience across devices

and platforms to our users.

• Store save games in the cloud and synchronize them

across all of a user’s devices without creating or

hosting a backend.

The Challenge

The solution

• Amazon Cognito helps us securely access our AWS

resources.

• Cognito Sync gives us flexibility to save data in the

cloud, and cache it on a user’s devices, without

managing any backend infrastructure.


Synchronize data across devices : Amazon Cognito (Sync)


Amazon Cognito Sync

User Data

Storage and

Sync

Any Platform

iOS/Android/FireOS

Store App Data, Preferences and StateSave app and device data to the cloud and merge

them after login

Cross-device Cross-OS Sync Sync user data and preferences across devices

with one line of code

Work OfflineData always stored in local SQLite DB first.

Works seamlessly when intermittent or no

connectivity

k/v data

Identity pool


Integrating Cognito Sync functionality is simple

Initialize the CredentialsProvider and CognitoClient

Call synchronize on the dataset

Create or open Dataset and Add Key Values

provider = new CognitoCachingCredentialsProvider (context, AWS_ACCOUNT_ID,

COGNITO_POOL_ID, COGNTIO_ROLE_UNAUTH, COGNITO_ROLE_AUTH, Regions.US_EAST_1);

cognito = new CognitoSyncManager (context, COGNITO_POOL_ID, Regions.US_EAST_1, provider);

dataset.synchronize(new SyncCallback(){..});

cognito.openOrCreateDataset(datasetName);

dataset.put(key, value);


Integrating Cognito Sync functionality is simple

Initialize the AWSCognitoSyncClient

Call synchronize on the dataset

Create or open Dataset and Add Key Values

DataSet *dataset = [syncClient openOrCreateDataSet:@"myDataSet"];

NSString *value = [dataset readStringForKey:@"myKey"];

[dataset putString:@"my value" forKey:@"myKey"];

AWSCognitoSyncClient *syncClient = [[AWSCognitoSyncClient alloc]

initWithConfiguration: configuration];

[dataset synchronize];

// Creating the transfer manager

self.transferManager = [S3TransferManager new];

self.transferManager.s3 = s3client;

// Upload image

[self.transferManager uploadFile:fileName bucket:bucketName key:objectName];

// Download image

[self.transferManager downloadFile:fileName bucket:bucketName key:objectName];

// Pause, Resume, Cancel

[self.transferManager pauseAllTransfers];

[self.transferManager resumeAllTransfers];

[self.transferManager cancelAllTransfers];

Outplay Entertainment – Amazon S3 Connector via Mobile SDK

Outplay Entertainment is mobile-focused game

developer on a mission to deliver fun, free and

innovative games for smartphones, tablets, and social

networks.

With Amazon S3 connector, we can

improve the users experience by

dynamically downloading game assets

in the background. No long up-front

delays for our users.

Douglas Hare

CEO, Outplay Entertainment

”

“ • Improved User Experience. Using the Mobile SDK,

they can download the game assets in background

while the user starts playing the game. No limits on

downloading extra assets.

• Dynamic updates. They can update the assets

dynamically and avoid AppStore release cycles.

• Unquestioned Scalability. Different assets for

multiple screen densities go up to 170 MB+. By

storing this data on S3 and directly downloading to

the mobile device, they can scale seamlessly.

• Excellent Performance. Highest resolution devices

end up downloading about 90MB of extra content.


Analyze User Behavior: Amazon Mobile Analytics


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


Getting Started with Mobile Analytics

in 3 steps

Sign up for AWS Account and create or use existing Cognito ID in

the AWS Management Console

View engagement and session activity reports in the

AWS Management console within minutes

Download and integrate the Mobile SDK with one line of

code (Android/FireOS, iOS)


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


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

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

Track Custom Events


Integrating Mobile Analytics is simple

Initialize the MobileAnalyticsManager. That’s it!

For Custom Events activity reports, add events.

Add OnResume() and OnPause()

private static MobileAnalyticsManager analytics;

analytics = MobileAnalyticsManager.getOrCreateInstance(

this.getApplicationContext(),"yourCompany.yourAppId",

Regions.YOUR_REGION, config, cognitoProvider );

EventClient eventClient = analytics.getEventClient();

MobileAnalyticsEvent visitEvent = eventClient.createEvent("speedSet");

eventClient.recordEvent(visitEvent);

analytics.getSessionClient().resumeSession();

analytics.getSessionClient().pauseSession();

Analytics.getEventClient().submitEvents();


Integrating Mobile Analytics is simple

Initialize the AWSMobileAnalytics object. That’s it!

Submit the event. If we don't call submitEvents, events

will automatically be submitted at periodic intervals.

Create add Custom Events

[eventClient submitEvents];

id<AWSMobileAnalyticsEventClient> eventClient =

analytics.eventClient;

id<AWSMobileAnalyticsEvent> level1Event = [eventClient

createEventWithEventType:@"level1Complete"];

AWSMobileAnalytics* analytics = [AWSMobileAnalytics

defaultAWSMobileAnalyticsWithIdentifier:@"someuniqueid"];

Store Shared Data: Amazon DynamoDB


Joe Anna Bob

Highscores

Joe 1500

Anna 800

Bob 750

Amazon DynamoDB Connector: Object Mapper

Simplifies access to Amazon

DynamoDB in your 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 = ”Highscores")

public static class HighScore{

private int id, highScore;

private String name;

@DynamoDBHashKey(attributeName = "id")

public int getId() {

return id;

}

public void setId(int id) {

this.id = id;

}

@DynamoDBAttribute(attributeName=”name")

public String getName() {

return name;

}……

id name highscore

17 Joe 25

23 Anna 67

32 Bob 55

Table: Highscores


Amazon DynamoDB: Example// Build a highscore object

HighScore highScore = new HighScore();

highScore.setId(17);

highScore.setName(”Joe");

highScore.setHighScore(25);

// Save book object to dynmaoDB

mapper.save(highScore);

// Update item and save object again

highScore.setHighScore(118);

mapper.save(highScore);

// Load another book

HighScore anotherHighScore = mapper.load(HighScore.class,23);


Amazon DynamoDB Best Practices

• Keep item size small

• Store metadata in Amazon DynamoDB and

large blobs in Amazon S3

• Use a table with a hash key for extremely

high scale

• Use table per day, week, month etc. for

storing time series data

• Use conditional/OCC updates

• Avoid hot keys and hot partitions

AWS Lambda

Auto Scaling

(Never under or over

provision)

Focus on business logic,

not infrastructure. Upload

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

Bring Your Own Code

“Run stateless functions in the cloud and scale without any servers to manage”

Starting with Javacript but

later bring your own code,

Create threads and

processes, run batch scripts

or other executables,


An Event Driven Asynchronous Code

Execution Platform.



Execution Platform.

1. Custom event

2. S3 Notifications

3. DynamoDB Changes

4. Kinesis



Execution Platform.How do invoke a function?

Directly Invoke on Lambda Console

Use SDK or CLI and call invoke-async

Registering an Event (S3, DynamoDB, Kinesis)

X Cron-ish

X RPC

X REST



Execution Platform.

• A call to a Lambda function is non-blocking.

• You do not wait for an answer.

• You just assume your function will be executed and your request

processed.



Execution Platform.

• Underlying Infrastructure is Entirely Managed for You!

• Supports Node.js only but more languages coming soon.

• Runs on Amazon Linux.

• Offers 500MB of /tmp storage.
