Editor's Notes
- Hi, My name is Dhruv Thukral and I am a Solutions Architect for Gaming here at AWS. I am joined by Tara Walker, who is a Technical Evangelist at AWS. The topic of our presentation is Build & Deploy Your Mobile Game with AWS. We have quite a few slides to go through so lets get started.
- So creating a mobile game is not just about the Mobile game anymore. The game itself is quite important, but there is a lot more to it.
- -First, You need to manage players in your game. Every mobile game or app these days is about acquiring and keeping players and so you want to be able to to provide as much flexibility to your players to be able to authenticate themselves. -You need to be able to provide value added features to these registered users which often means elevated access to your backend resources such as databases and storage. -You need to focus on users and not devices, most often players will play your game on multiple devices like an iPad and iPhone to a Android Tablet and Android Phone -A lot of games are driven by DLC, you need to be able to deliver this content to your users when they require it. No one likes to wait to be able to download a map pack or new level that they just paid for. -Analytics is a huge part of mobile gaming, I was once had a major mobile customer tell me we are a 70% analytics and a 30% gaming company. Now whether you agree or disagree with that philosophy, this trend is becoming a part of mobile gaming that cant be ignored. -You need to be able to constantly engage with your users. Usually hooked with the results of your analytics, you can target users with PN’s to inform them of new DLC, or send them promotional messages -Finally, with features such as leaderboards and highscores, you probably would want to save that shared data somewhere.
- We have a full range of services that are fully integrated with the rest of AWS offering, and optimized for mobile use cases, are accessible via a single Mobile SDK and share the same scalable, on-demand, global infrastructure of all our other AWS services.
- Cognito provides 3 major advantages Sync user data across devices Simplifies Management of users as unique identities across identity providers Implement AWS security best practices for accessing various AWS services
- And Lets first touch on the security aspect. We have seen a lot of developers tend to embed their AWS credentials in their app. These credentials are compromised if the app is decompiled. Amazon Cognito, eliminates the need to embed you AWS credentials in the app. Your mobile app authenticates with the identity provider (IdP) using the provider’s SDK. Once the end user is authenticated with the identity provider, the OAuth or OpenID Connect token returned from the identity provider is passed by your app to Amazon Cognito, which returns a new Cognito ID for the user and a set of temporary, limited-privilege AWS credentials. Amazon Cognito supports the creation and token vending process for unauthenticated users as well as authenticated users. Amazon Cognito creates a random, unique identifier for each unauthenticated user. You can use the unique identifier generated for your app users in your Identity and Access Management policies. For example you can create a policy for an S3 bucket that only allows a particular user access to their own folder thus setting granular access permissions on AWS resources.
- Architecturally, Amazon Cognito has two parts: Cognito identity Broker and Cognito Sync Store. Users first login with login provider of their choice and App with SDK does the rest. In the past, to access cloud services, developers embed aws credentials which is access key id and secret key within the application, this is highly unsecure because it is easy to unip the apk file and get access to keys. Now we make it extremely secure by not only create temprory creds that are valid only for one hour but also limiting the access to other data. The users only have access to store and sync in their own dataset. Once you get the temp cred, you can access other AWS services like S3 to store video, for example, DynamoDB to store shared data like leaderboards, kinesis to store streaming data logs and so on.
- With Amazon Cognito developers can synchronize application data across an end user’s devices with a single line of code. With Amazon Cognito, developers can securely store application data, such as preferences and game state in the AWS cloud. With synchronized application data, developers can give your users a consistent, unified experience on their app across all of their mobile devices. Developers can use Amazon Cognito directly from their mobile app without building or maintaining any backend infrastructure. Amazon Cognito handles secure application data storage and sync, enabling them to focus on their application experiences, instead of the heavy lifting of creating and managing a user application data sync solution. It manages the complexity of conflict resolution and intermittent network connectivity by managing offline cache ensuring your application can always deliver a great user experience. Each data set in the Amazon Cognito sync store can be synchronized on all devices associated with an identity simply by calling the synchronize () method.
- Here is some sample code that shows you how to use cognito sync. You first create a credentials provider, pass it your application context, your identity pool if and the region. You then pass the sync manager your credentials provider and your app context and region. Then adding values to dataset is as simple as opening a dataset. You can have upto a max of 20 datasets per identity so you can group your datasets into user_preferences, inventory, achievements etc, and then you simply add key value pairs to these datasets. To sync a dataset just call the synchronize method. By default the last update always wins in a sync call if you have multiple clients updating the same dataset.
- Handles multipart upload automatically to make the best use of bandwidth and you don’t have to worry about splitting the file into multiple chunks and keep track of the byte range requests.
- You create a new S3 client and use your previously created credentials provider. Then set the region. Then create a TU object and simply call the upload and download methods.
- 3 major advantages for Mobil Anayltics Measures the most commonly measured metrics automatically for you. It has a very generous free tier, 100M free events per month, 1 per M events Own your data, to be ingested in your processing and visualization tool of choice
- Quick Overview: Track nine pre-selected metrics in a simple to review dashboard to get a quick idea of engagement Active Users: Track how many users engage with your app daily and monthly and monitor sticky factor to gauge engagement, appeal, and monetization Sessions: Track how often your app is used on a given day and how often each user opens your app during a day Retention: Measure the rate at which customers come back to your app on a daily and weekly basis, after first use Revenue: Track in-app revenue trend data to identify areas for monetization improvement Custom Events: Track custom defined user actions specific to your app Sticky factor
- Custom Events let you track any action taken in your app, giving you an incredibly powerful insight into your user’s experience and behavior. Custom Events are often used to track social events such as number of Likes/Shares, app specific events such as play progress/song played, and in-app purchase events such as transactions per product SKU. Songs played is the custom even per session. Attribute numerical value associated with the data metric. Attribute: Weaponsused sword, how many people used the sword?
- You initialize the MA manager in a similar way. You pass in the app comntext, the appId and the identity pool id. Then for app session related events you called the Session Client, and for Custom Events, you call the Event Client.
- If you don’t call submitEvents, events will automatically be submitted at multiple intervals.
- Amazon SNS Mobile Push is a managed, scalable, cross-platform push intermediary service. It abstracts the complexity of different push notification services and allows developers to send push notifications across different mobile endpoints. You can subscribe to topics and and send messages which is then relayed to apple and google notifications services
- We discussed user data, now lets talk about shared data.
- It is highly likely that your app will have some data that you would want to share across users who will be on different platforms and devices. To ensure a fluid experience you would want quick and reliable access to the shared data. As an example, lets take one of the most common use cases in games – many games track high scores, leader boards and achievements to add a social element to the game and to increase user engagement. For that you need a quick access database in the cloud that you can query from the client. DynamoDB is a perfect solution for that. So what is DynamoDB? It is a fully managed NoSQL database service. Through its provisioned throughput model, it guarantees predictable performance. As your app can become an instant success overnight and your users can increase from 10s and 100s to 100 of thousands in matter of days. DynamoDB scales seamlessly. There is no cap in the table sizes and throughput limits. It uses SSD-based storage nodes that delivers low-latency access. And there is no administrative overhead. Now lets talk about how you can access DynamoDB from the AWS Mobile SDK in you Mobile App. In addition to the low-level APIs, we provide DynamoDB Object Mapper that simplifies access to Amazon DynamoDB. Using the Object Mapper, you can map you client-side classes to DynamoDB tables. The client library handles transforming the objects into tables and vice versa, eliminating the need for you to write redundant code. To see how easy it is to access DynmaoDB, lets look at an example
- Now in your mobile app, you can use DynamoDB defined annotations to map client side classes to DynamoDB tables. For this example, we will create a mapping class called Highscore which will have the same fields as the DynamoDB table and Get and Set method for each field.
- Next you will simple build a book object and set the required fields. To save the object to DynamoDB, you will simply use DynamoDBObjectMapper save(..) method To update the item again, simply update the fields in the object and call save(..) again. And finally to load another book, you can call the DynamoDBObjectMapper load(..) method and use the hash key. In this case we have set the id as the hash key.
- So imagine a case where your dynamodb key is user_id and you are storing everything for that use against that key, high scores, inventory, purchases etc in a per user JSON object. This will lead to a high number of changes and reads from the same key. So you end up with a hot key. Better to create multiple tables and spread it out. Separate tables for Inventory, Purchases etc.
- Event Driven: This mean Lambda executes code on an event. The event could be sourced from other AWS services, or could be something that you define on your own. You can also chain multiple events, and allow Lambda functions to trigger other Lambda functions. What kind of events are currently supported? Custom event: JSON data defined by your application in the call to the AWS SDK or CLI S3 Notifications: when an action is made on an Amazon S3 Bucket, the lambda function will be notified DynamoDB change: when a line is added, changed, removed from DynamoDB, the lambda function will be notified Kinesis: you can subscribe to a Kinesis stream Cannot access resources currently within a VPC
