This document discusses using AWS services to build a serverless backend for mobile apps. It describes how Amazon Cognito can be used for user authentication, data synchronization across devices, and security. Amazon Mobile Analytics is presented as a way to analyze user behavior in mobile apps. Amazon SNS is highlighted for its ability to send push notifications across platforms. Integrating these services is described as straightforward using the AWS Mobile SDK. The document emphasizes that developers can build full-featured mobile backends without having to manage their own infrastructure.

21. What does SNS do for us?
• PFT uses SNS for Native Push purpose
• SNS acts as an intermediate between our App and providers’ Native
Push System (Only one integration to build)
• SNS is also like a database of our users’ device identifier

41. Concrete Software builds cross platform mobile games
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.

42. Integrating Cognito Sync functionality is fast
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, Regions.US_EAST_1, provider);
dataset.synchronize(new SyncCallback(){..});
cognito.openOrCreateDataset(datasetName);
dataset.put(key, value);

43. Integrating Cognito Sync functionality is fast
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];

44. Analyze User Behavior: Amazon Mobile Analytics

45. What Customers Told Us About “Mobile Analytics”
Developers deeply value user analytics and consider it an integral part of
their app development process. They want to monitor their most
important metrics in a timely manner, and take action quickly. They would
like to own their mobile data, just like they do with any other AWS
service.

46. 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

47. Specific metrics related to your app and your business
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
Active users / Sessions / Revenue / Retention
Track Behavior Events

48. Integrating Mobile Analytics is fast
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();

49. Integrating Mobile Analytics is fast
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"];
