Chapter 14. Moving Applications to the Cloud

IN THIS CHAPTER

• Learning about cloud transactions

• Determining the best features to move to the cloud

• Seeing a cloud burst solution

• Knowing the factors of cloud application development

In this chapter, you learn about some of the important considerations involved in moving an application from a local or on-premises installation to one that is either fully or partly in the cloud. Some applications benefit from cloud deployment, and the cloud enhances some features.

The process for determining whether, what, and when to move your applications to the cloud involves an analysis of what critical features of the application need to be supported. After those critical features are understood, you can determine the features supported by your particular cloud service provider to see whether the cloud can support the application's critical features. Factors such as access to data, latencies, data security, and so on often limit what applications are good candidates for porting.

Two examples of application porting to the cloud are discussed in this chapter. In one application, physical hardware is eliminated by moving the entire application to the cloud. In the second example, a system is essentially cloned to the cloud to provide an overflow capability, an example of a hybrid application technique called cloud bursting.

When you move an application to the cloud, you must use the APIs of your particular cloud service provider. There are APIs for each of the ...
