Storage: How do we keep secrets secret? Proxy the requests Client sends data to web role Web role sends data to storage (1) (2) Web Role

Storage: Using Shared Access Signatures Client makes request of Web Role for SAS Web Role sends client SAS Client makes Read Request or Writes direct Client gets response (1) (3) Web Role (2) (4)

Next Steps Optimize storage calls of CreateIfNotExist Larger files upload blocks in parallel to the blob Windows Azure CDN Windows Azure Media Services Use CloudConfigurationManager to allow portability between WAWs and Cloud Services

Geolocation

Location Basics

Demo

using System.Data.Spatial; namespace GeoLocation.Models { public class PointOfInterest { public Guid Id { get; set; } [StringLength(200)] public string Description { get; set; } public PointOfInterstType Type { get; set; } public string Url { get; set; } public DbGeography Location { get; set; } } } public class LocationContext : DbContext { public DbSet PointOfInterest { get; set; } } using (var db = new LocationContext()) { return db.PointOfInterest.Where(p => p.Location.Distance(origin) <= radiusInMeters); } EF vs >= 5.0 with Spatial Data

Push Notifications

Demo

Handle MessageSendResult Implement Notifications in a Worker Role There is a very rich set of notification templates available in Windows 8. Become familiar with them: Win8TileTypes – Win8ToastTypes – Win8BadgeTypes – Next Steps Try the NuGets
