This document profiles Alexandre Marreiros and provides information about his background and expertise. It also includes brief descriptions of cloud connected web applications and how the Azure Mobile Apps service can be used to create a backend for mobile apps with features like offline sync, push notifications, and access to other Azure services. Code snippets demonstrate basic usage of Azure Mobile Apps for a todo list app.

10. Cloud Connected WebAPP
“A cloud connected mobile application is a mobile client that
connects to a mobile backend for shared services. Quite a few of
the apps on your phone are cloud connected already. For
example, Instagram uses the cloud for photo storage, and
Facebook uses the cloud to store the news feeds of you and your
friends.”

19. Azure Mobile Apps
Multiple languages and frameworks - App Service has first-class support for
ASP.NET, Node.js, Java, PHP, and Python
DevOps optimization - Set up continuous integration and deployment with Visual
Studio Team Services, GitHub, or BitBucket. Promote updates through test and
staging environments. Perform A/B testing.

21. Create a Mobile Service
MobileService = new MobileServiceClient(
"https://myapp.azurewebsites.net");

22. Create tables
IMobileServiceSyncTable<TodoItem> syncTable;
public async Task Init()
{
const string path = "syncstore.db";
var db = new MobileServiceSQLiteStore(path);
db.DefineTable<TodoItem>();
}
await MobileService.SyncContext.InitializeAsync(db);
syncTable = MobileService.GetSyncTable<TodoItem>();

23. Push and pull with sync table
private async Task SyncAsync()
{
await MobileService.SyncContext.PushAsync();
var query = syncTable.CreateQuery();
await syncTable.PullAsync("todoItems", query);
}
private async Task InsertTodoItem(TodoItem todoItem)
{
await syncTable.InsertAsync(todoItem);
await MobileService.SyncContext.PushAsync();
}

24. Query local table
public async Task<IEnumerable<TodoItem>> GetOpenItemsAsync()
{
return await todoTable
.Where(item => item.Complete == false)
.ToEnumerableAsync();
}

27. Notification Hub
• Maps between tags and handles
1. Get PNS handle
4. Send to device
2. Store PNS handle 3b. Request notification
Use device handles
3a. Request notification
Use logical users/tags
5. Manage device handles
