1 Design Comps Adobe Creative Suite HTML5, CSS, Media Responsive Web Design

2 Web Platform Neudesic Web Template Client: Open Standards Server: MS Web Platform 3 Integrate

Dynamic Content DB / Storage Data Binding Map Integration

4 Cloud-Ready Windows Azure Web Role / Instances Local Dev/Test

7 Global Worldwide Deployment Multiple Data Centers Traffic Management

5 Secured Single Sign-on Web / Domain ID

6 Deployed Elastic Scale Azure Data Center

AZURE WEB ROLE

1 Design Design Web Site Front-end & Create Assets

1A. Used an Adobe Dreamweaver HTML5 sample already set up for Responsive Web Design

1B. Customize Content in Dreamweaver – Page Title, Logo, Marquee Text,

1C. Hand-off to developer – assets are HTML5, CSS, JavaScript, image files

2 Adapt Template-based Web Project

2A. Create Project from Neudesic Web Template

2B. Insert front-end markup/styling/code/images from designer

• Move where some files are to match the templates organization

• Change paths in the HTML and CSS to match file relocation and use ASP.NET ~ path convention

• Segment HTML and insert into appropriate areas of the home view (Index.cshtml)

2B. Insert front-end markup/styling/code/images from designer

@* Optional : Include additional stylesheets *@ @section StylesTop { <link rel="stylesheet" type="text/css" href="~/../css/stylesheet.css" /> <link rel="stylesheet" type="text/css" media="only screen and (min-width:50px) and (max-width:550px)" href="~/../css/screen_small.css"> <link rel="stylesheet" type="text/css" media="only screen and (min-width:551px) and (max-width:800px)" href="~/../css/screen_medium.css">  }

2C. Final result is a web project we can run out of VS2010 with F5 – looks no diff from Step 1

3 Integrate Add Dynamic Content

3A. Create a Database for Promotional Data

3B. Retrieve Content in the MVC Project

public class HomeController : Controller { // // GET: /Home/ public ActionResult Index() { LoadPromos(); return View(); } private void LoadPromos() { Dictionary<string, Promo> Promos = new Dictionary<string, Promo>(); try { using (SqlConnection conn = new SqlConnection(System.Configuration.ConfigurationManager .ConnectionStrings["Tours"].ConnectionString)) { ...get the data, add to Promos collection... } } catch (SqlException ex) { // TODO: log exception } ViewBag.Promos = Promos; } }

public class Promo { public string Title; public string Text; public string ImageURL; }

3C. Embed Content with Razor

<div class="home_promo_container"> <div class="home_promo"> <div class="home_promo_content" style="background-image:url(images/@(ViewBag.Promos["1"].ImageURL));"> <h2 data-bind="text: PromoTitle1"></h2> <p data-bind="text: PromoText1"/> <a class="button" href="#">Learn more »</a> </div> </div> <div class="home_promo"> <div class="home_promo_content" style="background-image:url(images/@(ViewBag.Promos["2"].ImageURL));"> <h2 data-bind="text: PromoTitle2"></h2> <p data-bind="text: PromoText2"/> <a class="button" href="#">Learn more »</a> </div> </div> <div class="home_promo"> <div class="home_promo_content" style="background-image:url(images/@(ViewBag.Promos["3"].ImageURL));"> <h2 data-bind="text: PromoTitle3"></h2> <p data-bind="text: PromoText3"/> <a class="button" href="#">Learn more »</a> </div> </div> </div>

3C. Data Bind with Knockout

3D. Site with Data Binding

4 Cloud-Ready Set up for Windows Azure – Local Test/Dev in Simulator

4A. Add Windows Azure Project

4B. Set Instance Counts

<?xml version="1.0" encoding="utf-8"?> <ServiceConfiguration serviceName="ResponsiveSiteAzure" xmlns="http://schemas.microsoft.com/ServiceHosting/2008/10/ServiceConfiguration" osFamily="1" osVersion="*"> <Role name="ResponsiveSite"> <Instances count="4" /> <ConfigurationSettings> <Setting name="Microsoft.WindowsAzure.Plugins.Diagnostics.ConnectionString" value="UseDevelopmentStorage=true" /> </ConfigurationSettings> </Role> </ServiceConfiguration>

4C. Run locally in Windows Azure Simulation Environment

5 Secured Sign-in with web Identities

5A. Configure Access Control Service in Windows Azure

5B. Instrument for identity with Windows Identity Foundation

5C. Retrieve Claims

private void LoadClaims() { ViewBag.Welcome = "Welcome Back!"; var principal = Thread.CurrentPrincipal; var identity = principal.Identity as IClaimsIdentity; var claims = identity.Claims; ViewBag.Claims = claims; string displayName = null; if (claims != null) { string claimType; foreach (Claim claim in claims) { claimType = claim.ClaimType; if (claimType.EndsWith("/nameidentifier")) { displayName = claim.Subject.Name; break; } } if (!String.IsNullOrEmpty(displayName)) { ViewBag.Welcome = "Welcome back, " + displayName; } } }

6 Deployed Deployed to Windows Azure Data Center

6A. Move Promotional Item Images to Blob Storage

http://responsive.blob.core.windows.net/images/homepage_promo_1.jpg http://responsive.blob.core.windows.net/images/homepage_promo_2.jpg http://responsive.blob.core.windows.net/images/homepage_promo_3.jpg
