Putting the Cloud in Your PocketUsing Azure Mobile Services (.NET)

Consulting/Training

Thank You to Our Sponsors!

Consulting/Training

Cloud and mobile are in fact one and the same.

The mobile devices that users are flocking to are useless without the cloud.

And the cloud…is just a theory until you have a device that's both powerful enough to run apps that can take advantage of it and mobile enough that those apps are with you all the time, and working on your behalf.

The Two Parts of Azure Mobile Services

Client libraries Simplify using the REST APIs provided by the serverClient-side tooling (WAB, Offline Data Sync with SQLite)Source code for the client libraries is available on GitHub:

http://github.com/WindowsAzure/azure-mobile-services

Consulting/Training

Getting Started with the Windows Azure Mobile Services Portal

Consulting/Training

Out of the box support for SQL Azure, Azure Tables, Mongo DB

For SQL AzureAccess via EF6 Code-First

Automapper support is included to provide DB Entity to DTO Conversions

Use DB Migrations for schema updates

3 Steps: Data Model, Data Context, Data Controller

Data Storage

Consulting/Training

With the .NET client library, apps can either use strongly typed data objects or dynamic JSON objects

With strongly-typed data, object/table and property/column names can be aliased Using the DataTable attribute or the JsonProperty attribute

Table operations includeQuery(where, skip/take, orderby/thenby)

Lookup (find by id)

Insert

Update

Delete

Consuming Data Tables (.NET apps)

3 Execution Models for Server CodeTable Controller Methods (CRUD)

Custom API REST Endpoints

Scheduler Jobs

Services property provides access to Log, Push, Settings, Properties

Functionality can be extended with NuGet or other Assembly references

Server-Side Business Logic

Working with Data

Consulting/Training

Authentication & Authorization

Out of box supportMicrosoft Account, Twitter, Google, Facebook, Azure Active Directory

“Secret Values” stored on the server in the Portal, behind the firewall

Authentication FlowsServer-Flow: Server (Mobile Services) manages the authentication process

Client-Flow: Client authenticates on its own, passes token to server

AuthorizationScoped within the Controllers – entire controller or individual methods

Levels: Anonymous, Application, User, Administrator

Custom Authentication Extensibility

Consulting/Training

Facebook, Google, Microsoft Account

Specify in the portal’s “app settings” section

The authentication token that is obtained during login then supports requests for additional information from the identity provider

Available ValuesMicrosoft Account Scopes - http://j.mp/MicrosoftAccountScopes

Facebook Login Permissions - http://j.mp/FacebookPermissions

Google Authorization Scopes - http://j.mp/GoogleScopes

AuthN – Custom Scopes in the Server Flow

Notification Hub provisioned alongside your Mobile Service

Register for Push either via the Client API or relayed through the server

Optionally provide tags with registration

Server sends platform-specific push messages to the Notification Hub along with optional tags to filter targets

Push Notifications

Consulting/Training

1) The app requests and is issued a notification channel

2) The app registers this channel information and optionally some tags with the Mobile Service’s Notification Hub

3) An external event occurs that causes the Internet service to decide it should send notifications

4) The Internet service tells the Notification Hub to send notifications, optionally supplying one or more tags and optionally indicating a template to use

5) The Notification Hub iterates over its own list of applicable registrations, composes the payload appropriately, and sends the correct request to the notification services, managing failures, expired registrations, etc.

6) The notification services route notifications to the appropriate devices, where the payload and device settings determine how it should be displayed
