Overview of this book

Amazon Web Services (AWS) is the most popular and widely-used cloud platform. Administering and deploying application on AWS makes the applications resilient and robust. The main focus of the book is to cover the basic concepts of cloud-based development followed by running solutions in AWS Cloud, which will help the solutions run at scale. This book not only guides you through the trade-offs and ideas behind efficient cloud applications, but is a comprehensive guide to getting the most out of AWS. In the first section, you will begin by looking at the key concepts of AWS, setting up your AWS account, and operating it. This guide also covers cloud service models, which will help you build highly scalable and secure applications on the AWS platform. We will then dive deep into concepts of cloud computing with S3 storage, RDS and EC2. Next, this book will walk you through VPC, building real-time serverless environments, and deploying serverless APIs with microservices. Finally, this book will teach you to monitor your applications, automate your infrastructure, and deploy with CloudFormation. By the end of this book, you will be well-versed with the various services that AWS provides and will be able to leverage AWS infrastructure to accelerate the development process.

Designing for and Implementing High Availability

In this chapter, we will introduce some key design principles and approaches to achieving high availability in your applications deployed on the AWS cloud. As an enterprise or a start-up, you want to ensure that your mission critical applications are always available to serve your customers. The approaches in this chapter will address availability across the layers of your application architecture including availability aspects of key infrastructural components to ensure that there are no single points of failure.

In order to address availability requirements, we will use AWS infrastructure (Availability Zones and Regions), AWS Foundation Services (EC2 instances, Storage, Security and Access Control, and Networking), and AWS PaaS services (DynamoDB, RDS, CloudFormation, and so on). In addition to availability, we will describe...
