Introducing Windows Azure- P11

Introducing Windows Azure- P11:The cloud platform is getting more and more attractive to the computing world. Today, service-oriented architecture (SOA) and aspect-oriented programming (AOP) techniques are widely used in enterprise solutions. A question an IT management team or a software development team may ask is, what is the next trend going to be? Cloud computing seems to be the right answer. | CHAPTER 1 CREATE CLOUD TABLE STORAGE Close SQL Analysis When creating a test cloud storage table any active SQL query analysis running against the existing cloud storage table needs to be closed from SQL Management Studio to avoid the failure of data storage creation. Summary As we have learned so far creating cloud table storage is a straightforward job. Microsoft claims that the Azure framework is a true developer-oriented framework. All the hard work should have been done and encapsulated in the SDK. Your life as a .NET developer is now a lot easier what remains for you to do is nothing but derive your client classes from the base classes from the SDK and follow the right procedures to build your cloud applications. However I have not presented how to access cloud table storage yet. That is the task we are going to pursue in the next chapter. 23 C H A P T E R 2 Access Cloud Table Storage To access Azure table storage we must use Azure web roles since the worker role cannot connect to or communicate with the outside world directly. A worker role is usually used on batch jobs see the book s introduction . The Azure SDK provides a set of templates in a client service access library StorageClient.dll. This chapter has three exercises. In the first section of this chapter we will walk through a process to access cloud storage step by step and see how to use these templates to insert and query data using the cloud table storages. The second exercise focuses on deleting the records from a cloud storage table. The third exercise is an example of how to manipulate data in tables with a relational structure. The cloud storage we are going to use was created in Chapter 1. From these three exercises you will learn the basic skills to deal with cloud table storage. Essentially all cloud tables are addressable using a URI. The cloud table can be accessed by a web request via HTTP. The Azure SDK provides client-side components that implement all the base classes used to access
