11. Why Azure?

12. azure Windows Azure is the foundation of Microsoft’s Cloud Platform It is an “Operating System in the Cloud” and provides Essential Services for the cloud  Virtualized Computation  Scalable Storage  Automatic Management  Developer SDK

15. Azure Roles An Azure application is implemented with a Web and/or a Worker role.  Developer defines what the role does.  Azure takes care of the rest.  Each VM assigner to a role.

16. Azure Roles

17. Stateless Azure Web Roles must be designer to be stateless  Request from the same user may reach different web role instances.  Store state in Azure storage or client side.

18. Stateless

19. Windows Azure data storage Azure allow data to be stored in:  Blobs (large items of user data)  Tables(simple tables, caches)  Queues(service communicationz) Massive scale, availability and durability. Everything is accessible via RESTful services.

20. Fundamental data abstractions Blobs – Provide a simple interface for storing named files along with metadata for the file Tables – Provide structured storage; A Table is a set of entities, which contain a set of properties Queues – Provide reliable storage and delivery of messages for an application

21. Windows Azure data storage

22. Windows azure tables Provides Structured Storage  Massively Scalable Tables Billions of entities (rows) and TBs of data Can use thousands of servers as traffic grows  Highly Available Can always access your data  Durable Data is replicated several times Familiar and Easy to use API  ADO.NET Data Services –.NET 3.5 SP1.NET classes and LINQ REST – with any platform or language

23. Agenda Data model Demo – creating Tables Demo – creating Blobs Demo – creating Queues Basic CRUD using.NET and REST Best Practices Demo – A better Approach

24. Data model Table  A Storage Account can create many tables  Table name is scoped by Account Data is stored in Tables  A Table is a set of Entities (rows)  An Entity is a set of Properties (columns) Entity  Two “key” properties that together are the unique ID of the entity PartitionKey – enables scalability RowKey – uniquely identifies the entity within the partition

25. partition Table Partition – all entities in table with same partition key value Application controls granularity of partition

26. partition Table Partition – all entities in table with same partition key value Application controls granularity of partition Partition Key Item Row Key ModelNo Property 3 Sold Property 4 LaptopM1.0.0.010/1/2010 LaptopM1.0.0.123/1/2010 PCV1.05/2/2007 PCV1.0.17/6/2007 PCV1.0.28/1/2007

27. Partiton guidelines Performance  Use a PartitionKey that is common in your queries Entities with same partition key value are clustered Scalability  We monitor partition traffic  Automatically load balance partitions Each partition can potentially be served by a different storage node Scale to meet the traffic needs of your application  More partitions – makes it easier to balance load

28. DEMO TALK IS CHEAP. SHOW ME THE CODE - LINUS TORVALDS

29. entities and properties Each Entity can have up to 255 properties Every Entity has fixed key properties  Partition key  Row key No fixed schema for rest of properties  2 entities in the same table can have different properties  Properties stored as pairs Each entity has a system maintained version

30. Automated service management Our responsibilities  Develop and model the service.  Deploy the service to the cloud.  Configure the settings and constraints. Azure’s responsibilities  Run the service.  Maintain the service’s health.  Configure the settings and constraints.

31. Azure services

33. Property types Partition key and Row key  String (up to 64KB) Other properties  String (up to 64KB)  Binary (up to 64KB)  Bool  DateTime  GUID  Int  Int64  Double
