35 Synchronize data across devices : Amazon Cognito (Sync)

36 What have customers told us about Synchronized Profile People have multiple devices and want to transition between devices. Implementing a user profile that syncs across devices, OS, apps is hard. It not only has to work when offline, but easy to integrate with existing apps.

37 Amazon Cognito Sync Store App Data, Preferences and State Save 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 User Data Storage and Sync Identity pool k/v data Work Offline Data always stored in local SQLite DB first. Works seamlessly when intermittent or no connectivity Any Platform ios/android/fireos

38 Amazon Cognito Sync Offline: The client SDK manages a local SQLite data store to allow the app to work even when connectivity is not available. Fast: The methods to read and write data only interact with the local SQLite database. Intelligent Sync: The sync method compares the local version of the data to the cloud sync store, pushes up deltas and pulls down new changes. Local SQLite Cache Flexible Conflict resolution: The sync method first reads the changes then writes its local changes to the cloud sync store By default Cognito assumes that the last write wins. Developers can override and implement their own conflict resolution programmatically

39 Integrating Cognito Sync functionality is dead simple Initialize the CredentialsProvider and CognitoClient provider = new CognitoCredentialsProvider(context, AWS_ACCOUNT_ID, COGNITO_POOL_ID, COGNTIO_ROLE_UNAUTH, COGNITO_ROLE_AUTH); cognito = new DefaultCognitoSyncClient(context, COGNITO_POOL_ID, provider); Create or open Dataset and Add Key Values cognito.openorcreatedataset(datasetname); dataset.put(key, value); Call synchronize on the dataset dataset.synchronize(new SyncCallback(){..});

40 Integrating Cognito Sync functionality is dead simple ios Initialize the AWSCognitoSyncClient AWSCognitoSyncClient *syncclient = [[AWSCognitoSyncClient alloc] initwithconfiguration: configuration]; Create or open Dataset and Add Key Values DataSet *dataset = [syncclient openorcreatedataset:@"mydataset"]; NSString *value = [dataset readstringforkey:@"mykey"]; [dataset putstring:@"my value" forkey:@"mykey"]; Call synchronize on the dataset [dataset synchronize];

41 Analyze User Behavior: Amazon Mobile Analytics

42 User Analytics Is the Most Adopted Mobile Developer Tool

43 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.

44 Amazon Mobile Analytics Easily collect, visualize and understand your app usage data at scale Fast Scalable and Generous Free Tier Own Your Data Focus on metrics that matter. Usage reports available within 60 minutes of receiving data from an app Scale to billions of events per day from millions of users. Data collected are not shared, aggregated, or reused

45 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 Download and integrate the Mobile SDK with one line of code (Android/FireOS, ios) View engagement and session activity reports in the AWS Management console within minutes

46

47 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

48 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

49 Track Custom Events 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 Number of songs played, per user session, in a music app In-app item popularity in a shopping app Understand player abort rates per level, in a game

50 Integrating Mobile Analytics is super simple Initialize the AmazonMobileAnalyticsClient. That s it! Get Session Activity in the AWS Management Console. analytics = new AmazonMobileAnalytics(provider, context, "SnakeGameAWS ); Add OnResume() and OnPause() analytics.getsessionclient().resumesession(); analytics.getsessionclient().pausesession(); Analytics.getEventClient().submitEvents(); For Custom Events activity reports, add events. EventClient eventclient = analytics.geteventclient(); MobileAnalyticsEvent visitevent = eventclient.createevent("speedset"); eventclient.recordevent(visitevent);

51 Integrating Mobile Analytics is super simple ios Initialize the AmazonMobileAnalytics object. That s it! Get Session Activity in the AWS Management Console. AWSMobileAnalytics* analytics = [AWSMobileAnalytics defaultawsmobileanalyticswithidentifier:@"someuniqueid"]; Create add Custom Events id<awsmobileanalyticseventclient> eventclient = analytics.eventclient; id<awsmobileanalyticsevent> level1event = [eventclient createeventwitheventtype:@"level1complete"]; Submit the event. If we don't call submitevents, events will automatically be submitted at periodic intervals. [eventclient submitevents];

52 Store and share media: Amazon S3

53 Amazon S3 Connector: Transfer Manager S3 Connector Multipart upload/download media to/from S3 (photos, videos, audio) No backend required Automatic retries Pause, resume, cancel functions Amazon S3

54 Amazon S3 Connector: Transfer Manager // 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];

55 Send Push Notifications: Amazon SNS Mobile Push

56 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.

57 Each platform works differently, and push gets even more complex as you scale to support millions of devices. Cloud App Platform Services Mobile Apps
