Summary

In this chapter, we explained the differences in design and implementation of cloud-based application. We reviewed some of the architectural best practices in the cloud context. More specifically, we described multi-tiered, loosely coupled, and service oriented scalable designs and their realizations on the cloud platform. We also went through the design consideration and implementation approaches to multi-tenancy. We also created a simple application that we intend to expand and elaborate in the coming chapters to illustrate the AWS concepts in detail.

After covering the cloud architectural principles in this chapter, we will get a lot more specific in our coverage of cloud computing in the next chapter. We will cover the AWS-specific cloud services, the costing model, and application development environments.
