1. The document provides an overview of Windows Azure offerings including Compute, Storage, SQL Azure, Virtual Network, AppFabric, and Marketplace. 2. It discusses the "7 Deadly Sins of Cloud Development" including under utilization of cloud resources, platform monogamy, poorly defined release cadence, always connected assumptions, synchronous application design, lack of load/failover testing, and lack of cloud reading. 3. The document includes demos of various Windows Azure features to illustrate how to avoid the sins.

4. Windows Azure Compute

5. Windows Azure Compute
A Hosted Service is a container for an Application.
An Application must consist of at least one Role.
A Role is Scalable to meet the demand of traffic.

7. Windows Azure Storage
Blob Files with accompanying Meta Data
Table Non-Relational Entity Storage
Queue Reliable Message Delivery for Applications
Drives Durable NTFS VHD [Mountable]

8. Windows Azure Storage

9. SQL Azure
 Tables, indexes and views
 Stored Procedures
1GB, 5GB 10-50GB  Triggers
 Constraints
 Table variables,
session temp tables (#t)
Web Edition Business Edition  Spatial types, HierarchyId
 Data Types

12. Virtual Network
On-Premise Windows Azure
[IP-Sec Connectivity] Web Role 1
Remote Office
Web Role 2
Windows Azure Connect

13. Virtual Network
Load Balance an Application using {0} based routing.
Performance – Route traffic to best suited Hosted Service based on ping.
Failover – Route traffic to standby Hosted Services while primary is offline.
Round Robin – Route traffic equally between configured Hosted Services.
