Sync scalability is extremely hard
Expensive to manage and operate
Distracts them from building core UX
Managing unique user identities is difficult
“Table stakes” for every app
Undifferentiated Heavy Lifting

17. Amazon Cognito Sync Data Model
• Identity
Pool:
Pool
of
app
users.
Can
be
shared
across
apps.
• Identity:
An
individual
user.
Consistent
across
identity
providers.
Can
be
a
guest
user.
• Dataset:
Per
user
grouping
of
data.
The
most
granular
level
of
sync.
Up
to
1
MB.
• Record:

18. Integrating Amazon Cognito Sync
Functionality Is Dead Simple
Initialize the CredentialsProvider and CognitoClient
Call synchronize on the dataset
Create or open the dataset and add key values
provider = new CognitoCachingCredentialsProvider (context, AWS_ACCOUNT_ID,
COGNITO_POOL_ID, COGNITO_ROLE_UNAUTH, COGNITO_ROLE_AUTH, Regions.US_EAST_1);
cognito = new CognitoSyncManager (context, Regions.US_EAST_1, provider);
dataset.synchronize(new SyncCallback(){..});
cognito.openOrCreateDataset(datasetName);
dataset.put(key, value);

19. Integrating Amazon Cognito Sync
Functionality Is Dead Simple
Initialize the AWSCognitoSyncClient
Call synchronize on the dataset
Create or open the 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];

20. Analyze User Behavior: Amazon Mobile Analytics

21. 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
“Simply and cost-­effectively collect and analyze your application usage data”
Data collected are not
shared, aggregated, or
reused

22. 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

23. 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.

24. 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 for 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
Track Custom Events

25. Integrating Mobile Analytics is super simple
Initialize the MobileAnalyticsManager. That’s it! Get Session
Activity in the AWS Management Console.
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();

26. Integrating Mobile Analytics is super simple
Initialize the AWSMobileAnalytics object. That’s it! Get Session
Activity in the AWS Management Console.
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"];

// Creating the transfer manager
TransferManager = new TransferManager(credentialProvider);
// Upload image
Upload upload = transferManager.upload(BUCKET_NAME, fileName, file);
// Download image
Download download = transferManager.download(BUCKET_NAME, mKey,
file);
// Pause, and Resume
try {
PersistableDownload = download.pause();
//do something if we didn’t abort
} catch(PauseException e) {
//do something if we aborted
}
download = transferManager.resumeDownload(persistableDownload);

34. Amazon S3 Connector: Transfer Manager in iOS
// 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];

Call synchronize on the dataset
Create/Upload the Lambda function to the AWS Management Console
lambda = new LambdaInvokerFactory(context, Regions.US_WEST_2, provider);
//interface
@LambdaFunction(functionName="cloudFunction”)
String localFunction(String nameInfo);
lambda.localFunction(“Hello From “); // this will output “Hello From Lambda”
exports.handler = function(event, context) {
context.done(null, event + 'Lambda'); // SUCCESS with message
};
