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.

Evolving architecture against increasing loads

Auto scaling is not the single thing that fixes everything. In real life, you will probably evolve your architecture against an increasing number of users or load. In this section, we will suggest actions you can take at each stage of your growth starting from a handful of users right up to tens of millions of users for a typical web stack.

Scaling from one to half a million users

In the beginning, you can get started with a single EC2 instance that hosts your web service and the DB on the same instance. You can provision an EIP and use Route53 for DNS services. This should be sufficient to handle a typical website or service for a new business.

As your number of users increases...
