Chapter 4. Designing for and Implementing Scalability
In this chapter, we will introduce some key design principles and approaches to achieving scalability in your applications deployed on the AWS cloud. As an enterprise, or a start-up at its inflection point, you never want your customers to be greeted with a 503 message (that is, Service Unavailable). The approaches in this chapter will ensure your web and mobile applications scale effectively to meet your demand patterns, growth in business, and spikes in traffic. We will also show you how to set up auto scaling in order to automate the scalability in our sample application.
In this chapter, you will learn the following topics:
Defining scalability objectives
Designing scalable application architectures
Leveraging AWS infrastructure services for scalability
Setting up auto scaling for your deployed application
