Lo scenario Mobile/Smartphone/Apps

Mobile (oggi)…

…domani ci saranno tanti nomi: Devices

Intelligente Devices

Internet of Things

App è il modello delle applicazioni che provengono da uno «shop» Tipico per questo tipo di dispositivi

Anche nei PC (es. Windows 8) ora si chiamano App

App=Client+Services

Quando parliamo di app, pensiamo subito allo smartphone e alla «grafica»

Una app non funziona mai da sola

Parliamo di applicazioni «connesse» Il valore dello smartphone è essere «online»

Sei online perché comunichiamo con dei servizi Identità (Facebook, live.it, gmail.com, linkedin, …)

Email (Live, Gmail, …)

Storage drives (OneDrive, GoogleDrive, DropBox, ….)

…

Se tutti percepiamo come scrivere una app, come scriviamo un servizio?

Servizi per le App

I servizi per le app sono composti da due parti fondamentali Il Codice

L’infrastruttura

Il codice è la parte «che fa il lavoro» Lo scriviamo in qualche linguaggio (Javascript+HTML, C# e XAML, Java, PHP, ….)

L’infrastruttura dà gli «attributi» al servizio Qualità

Disponibilità

Funzionalità

Introduzione al Cloud Computing

e Microsoft Azure

Cos’è il Cloud Computing

L’approccio moderno alla implementazione di servizi per le App

Cos’è il Cloud Computing

An approach to computing that’s about internet scale and connecting to a variety of devices and endpoints

What are Mobile Services?

Data

Notifications

Auth

Server Scripts + Custom API

Scheduler

Logging & Diag

Scale

Structured Storage

Powered by SQL Database

Same DB – Multiple Mobile Services AppX.Todoitem

AppY.Todoitem

Data management in Windows Azure Portal

SQL Portal, SQL Management Studio

REST API

CLI Tools

The REST API

Action HTTP Verb URL Suffix

Create POST /TodoItem

Read GET /TodoItem?$filter=id%3D42

Update PATCH /TodoItem/id

Delete DELETE /TodoItem/id

Data Operations and their REST Equivalents

Base REST API Endpoint URL

https://Mobileservice.azure-mobile.net/tables/*

JSON to SQL Type Mappings

JSON Value T-SQL Type

Numeric values (integer, decimal, floating point)

Float(53)

Boolean Bit

DateTime DateTimeOffset(3)

String Nvarchar(max)

Auth*

Authenticate against Microsoft Account, Twitter, Facebook, Google

Table level permissions for each CRUD operation Everyone

Anyone with the Application Key

Only Authenticated Users

Only Scripts and Admins

More granular control with server side scripts user.level: {admin, authenticated, anonymous}

user.userId: id or undefined if not authenticated

The User object

User.level Anonymous

Authenticated

Admin

User.userId Provider:id or undefined

User.getIdentities() UserId

Provider Access Token / Secret

Raggiungere l’utente: push notifications

Push Notifications

Integrates with WNS to provide Toast, Tile, Badge and Raw notifications

Portal captures your WNS client secret and package SID

push.wns.* provides: clean easy object model to compose notifications

Performs auth against WNS for you

How Push Notifications Work

Retrieve device handle

PNS(APNS, WNS, GCM)

Store handle in app back-end Send notification to handle

Device notified (even when app is inactive)

Server Side Scripts

Customizing logic on the server

Node.js scripts

Passes through to SQL by default

Intercept CRUD requests to tables

Fully customizable logic flow

Node Modules

Extensibility through numerous included modules

request

console

push.*

mssql

statusCodes azure

sendgrid

pusher

twilio

How Service Bus Notification Hub Works

Retrieve device handle

PNS

Registration with tagsSend notification to handle

Azure Mobile Services:other goodies

More on script options: Custom API

Non-table based scripts

Accessible from Get

Post

Put

Patch

Delete

Same permissions as tables

Storage: What are our options?

Benefits: Non-relational structured storage

Massive scale-out

Tables Storage

Benefits: Big filesBlobs

Benefits: Persistent Async Messaging

Enqueue, Dequeue

Queues

Benefits: Relational database

Highly available

Managed for you as a service

SQL Database

Script Source Control

Handled through GIT repo

• Access to table, scheduler, custom API, shared scripts, and permissions

Shared Scripts

• Make scripts accessible from other scripts

• Just like creating Node.js modules NPM

• Ability to use ‘npm install module’ to download NPM modules

Conclusions

Conclusions

il Cloud Computing è la piattaforma di riferimento per complementare la parte «client» di una App

Microsoft Azure è la piattaforma Cloud di riferimento per ricchezza di servizi e molteplicità di modelli per lo sviluppo

Azure Mobile Services sono una piattaforma che semplifica l’acceso al Cloud per chiunque voglia scrivere app… …avendo subito servizi di classe enterprise

…ma potrà scalare a modelli e livelli di servizio ancora più alti
