Authenticate users: Amazon Cognito

Amazon Cognito

Simplifies identity and

access management

Securely access all

AWS services from

mobile device

Cross-device and

cross-platform syncImplement security best

practices

“Your app data is secure, available offline, and kept in sync between devices”

Synchronize user’s data

across devices and

platforms

Manage users as

unique identities across

identity providers

Guest Your own

Auth

Amazon Cognito concepts

Identity pool

IAM roles, trust, and permissions

Identities: authenticated and unauthenticated

Getting started

Create an identity pool

Use SDK to get credentials

Create roles: authenticated and unauthenticated

Getting credentials

Include the following import statements

Initialize the Amazon Cognito credentials provider

Pass the initialized Amazon Cognito credentials provider to the constructor of

the AWS client to be used. This could be the Amazon Cognito Sync client,

the Amazon S3 transfer manager, or any of the other mobile services we will

talk about shortly.

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 Amazon Cognito Sync functionality is simple

Import the Amazon Cognito package

Initialize the Sync client and use the previously created credentials provider

Datasets

Create a dataset or open an existing one

To delete a dataset

Reading and writing to a dataset

Removing keys from a dataset

Store and deliver media assets:

Amazon S3 and Amazon CloudFront

Amazon S3 Connector: Transfer Utility

S3 Connector

• Multipart upload (e.g., user content)

• Fault tolerant download (e.g., assets)

• No back end required

• Automatic retries

• Pause, resume, cancel functions

Integrating the S3 Transfer Utility is simple too!

Instantiate an Amazon S3 client

Instantiate TransferUtility

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

Integrating Mobile Analytics is guess what….simple!

Initialize the MobileAnalyticsManager and that’s it….

We saw earlier where we can find our identity pool ID.

You can get the appid by creating a new app in the Mobile Analytics dashboard

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

Amazon Mobile Analytics dashboard

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 and 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

Custom event tracking using Mobile Analytics

Create an AnalyticsEvent, pass attributes and metrics

Then record the event

Send push notifications: Amazon SNS mobile push

Each platform works differently, and push gets more complex as

you scale to support millions of devices

DynamoDB tables

Removes the need to transform

objects into tables and vice versa

Amazon DynamoDB Connector: Object Mapper

@DynamoDBTable(tableName = ”Highscores")

private int userid, highScore;

private String name;

@DynamoDBHashKey(attributeName = ”userid")

public int getUserId() {

return userid;

}

public void setUserId(int userid) {

this.userid = userid;

}

@DynamoDBAttribute(attributeName=”name")

public String getName() {

return name;

}……

User ID Name High score

17 Joe 25

23 Anna 67

32 Bob 55

Table: high scores

Amazon DynamoDB mapper example

// Build a highscore object

HighScore highScore = new HighScore();

highScore.setUserId(17);

highScore.setName(”Joe");

highScore.setHighScore(25);

// Save book object to DynamoDB

mapper.save(highScore);

// Update item and save object again

highScore.setHighScore(118);

mapper.save(highScore);

// Load another highScore

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

Adding DynamoDB

Methods to create DynamoDB table

Using DynamoDB console

Using code with createTable method

Using Visual Studio with AWS Toolkit for Visual Studio: http://aws.amazon.com/net/

Example:

• Table name: TappyHighScores

• Primary key type: Hash

• Hash attribute name: ScoreID,

• Hash type: Number

Create DynamoDB clientAmazonDynamoDBClient client = new

AmazonDynamoDBClient(RegionEndpoint.USEast1)

Using DynamoDB

Add a high score record

Create high score object

[DynamoDBTable(”TappyHighScores")]

class HighScore

{ [DynamoDBHashKey] // hash key

public int ScoreID { get; set; }

[DynamoDBProperty]

public string Score { get; set; }

public string UserID {get; set; }

}

Save high score record to DynamoDB

_context.SaveAsync<HighScore>(myScore,

(AmazonDynamoResult<VoidResponse> result) =>

{ if (result.Exception != null) { this.displayMessage += "Save

failed ; “ +result.Exception.Message; }

Adding Amazon Simple Storage Service (S3)

Methods create S3 bucket (set permissions)

Using Amazon S3 console

Using code with PutBucket and PutBucketRequest

Using Visual Studio with AWS Toolkit for Visual Studio:

http://aws.amazon.com/net/

Example:

Bucket name: tappyplane_bucket

Create an Amazon S3 transfer managerAmazonS3Client S3Client =

new AmazonS3Client (credentials ,RegionEndpoint.USEast1);

Using Amazon Simple Storage Service (S3)

Download an object

Get badge picture (bragging rights)

var request = new GetObjectRequest ()

{ BucketName = bucketName,

Key = downloadKey,

};

S3Client.GetObjectAsync (request, GetObjectCallback,null);

Upload an object

Upload a picture of high score

Stream stream = null;

stream = new FileStream(uploadSrcFilePath, FileMode.Open,

FileAccess.Read, FileShare.Read);

var postRequest = new PostObjectRequest
