Overview of this book

With the increasing global interest in leveraging cloud infrastructure, AWS Cloud from Amazon offers a cutting-edge platform for architecting, building, and deploying web-scale cloud applications. The variety of features available within AWS can reduce overall infrastructure costs and accelerate the development process for both large enterprises and startups alike. Beginning with basic cloud concepts, you'll learn about the various cloud services models and the design implications of multi-tenant applications. You'll then design, implement, and deploy a multi-tier, scalable, highly-available and secure application on the AWS platform. At every step, we explain the key guiding principles driving real-world production-ready application architectures. Finally, you will learn how to automate your cloud infrastructure, set up operations, application monitoring, and DevOps pipeline.

Designing scalable application architectures

In this section, we present some of the common approaches to designing scalable application architectures. Some of these design principles are not unique to cloud-based applications; however, they become even more important in the cloud context. Let's have a look at a few of these design principles.

Using AWS services for out-of-the-box scalability

Leverage AWS PaaS services wherever possible to receive the benefits of scalability and availability without the associated administrative headaches or design complexity. For example, you can leverage the RDS or the DynamoDB services available for scalable relational and NoSQL database services, respectively. Similarly, you could leverage the AWS SQS for a highly scalable queuing service without having to roll out your own implementation or managing an open source product deployed in an EC2 instance.

Using a scale-out approach

Designing an application that can scale horizontally allows you to distribute...
