Cloud computing is Internet-based computing, whereby shared

other devices on demand, like the electricity grid.

Huh .. say that again?
The Cloud is just another place to host your code/stuff, but you are
billed like a utility.
Comes with fluff & scalability
Augment your Mobile Solutions with cloud support.
Practicality?

Push Notifications

It’s not always Sunny & 73o !!

Push Notifications Contd.
 Notification types – Live Tile Update, Toast or Raw; depending on type, notification is sent either to App
or Shell.
 Tile – visual dynamic representation of application content within phone’s start page, if pinned by user
(through Context Menu); ongoing communication to user based on frequency of cloud service actions;
the backend cloud service can control a tile’s background image (may be expensive if no local resource)
& counter, as configured.
 Toast – displays notification as an overlay onto user’s current screen; intrusive & hence to be used
sparingly; user may touch to launch application; cloud service may control title & subtitle of toast;
appropriate for peer-to-peer apps; users have to have an explicit option to agree to toasts.
 Toast and Tile notification are system defined notification in Windows Phone 7 platform.
 Raw – App can receive messages from cloud constantly using PN; eliminates need for custom code to
have persistent connection open with backend cloud service; only possible if app running in
foreground.
 Enhanced Push Notifications in Mango – Improved TDET detection, Fast resume of channel, Max
channels up to 30 now and API enhancements to handle multiple 2-sided tiles & deep-linked Toasts.

O(h my ) Data
 “JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for humans to read
and write. It is easy for machines to parse and generate. It is based on a subset of the JavaScript
Programming Language, Standard ECMA-262. JSON is a text format that is completely language
independent but uses conventions that are familiar to programmers of the C-family of languages,
including C, C++, C#, Java, JavaScript, Perl, Python, and many others. Most JSON comprises of a collection
of name/value pairs & ordered list of values.”
 “Atom is an XML-based document format that describes lists of related information known as "feeds".
Feeds are composed of a number of items, known as "entries", each with an extensible set of attached
metadata. For example, each entry has a title. The primary use case that Atom addresses is the
syndication of Web content such as weblogs and news headlines to Web sites as well as directly to user
agents.”
 “In very simple terms, OData is a resource-based Web protocol for querying and updating data. OData
defines operations on resources using HTTP verbs (PUT, POST, UPDATE and DELETE), and it identifies those
resources using a standard URI syntax. Data is transferred over HTTP using the AtomPub or JSON
standards. (Source: MSDN Magazine, June 2010 Issue)”
 Services that expose their data using the OData protocol are referred to as OData producers, and
clients that consume data exposed using the OData protocol are referred to as consumers. Head over
to http://odata.org for more information about OData, a list of current producers & consumers and
what all this means for developers.
 The OData protocol enables access to information from a broad range of clients. At present, the
ecosystem has client libraries available for Windows Phone 7, iPhone, Silverlight 4, PHP, AJAX/Javascript,
Ruby, or Java.

Some more love ..
 Think of it as RSS for real updateable data
 Share Data & associated MetaData
 Imp keyword: $metadata & $format (may not honored by WCF Data Service by default; use HTTP headers)
 Filtering, Ordering & Paging (server-side, with cont. token) support
 Starting to be a regular part of a lot of the MSFT stack or cloud-based products
 And no, this is not a MSFT thing 
 Possible to supply Credentials through HTTP Stack:

Live Services
• Your users possibly use Live Services already
• SkyDrive, Hotmail & Messenger
• The Live Connect APIs use standard protocols such as HTTP, OAuth 2.0, JSON,
XMPP & REST
• All API details @ https://manage.dev.live.com
• Use what’s familiar to your users
• Syncs across their devices

15.
Windows Azure Toolkit for WP
• http://watwp.codeplex.com/
