Preface

With an increasing interest in leveraging cloud infrastructure around the world, the

AWS cloud from Amazon offers a cutting-edge platform for architecting, building,

and deploying web-scale cloud applications through a user-friendly interface. The

variety of features available within AWS can reduce overall infrastructure costs and

accelerate the development process for both large enterprises and start-ups alike.

Learning AWS covers basic, intermediate, and advanced features and concepts

as they relate to designing, developing, and deploying scalable, highly available,

and secure applications on the AWS platform. By sequentially working through

the steps in each chapter, you will quickly master the features of AWS to create an

enterprise-grade cloud application. We use a three-tiered services-oriented sample

application for extensive hands-on exercises.

This book will not only teach you about the AWS components, but you will gain

valuable information about key concepts such as multi-tenancy, auto scaling,

planning, implementing application development environments, addressing

application security concerns, and so on. You will also learn how these concepts

relate to cost effective architectural decisions while designing scalable, highly

available, and secure AWS cloud applications.

A step-by-step approach to cloud application design and implementation is explained

in a conversational and easy-to-follow style. Each topic is explained sequentially in

the process of creating an AWS cloud application. Detailed explanations of the basic

and advanced features of AWS that address the needs of readers with a wide range

of real-world experiences are also included. Expert programmers and architects will

appreciate the focus on the practice rather than the theory.

What this book covers

Chapter 1, Cloud 101 – Understanding the Basics, describes basic cloud concepts

including the public, private, and hybrid cloud models. We explain and compare the

Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS), and Software-as-a-

Service (SaaS) cloud service delivery models. In addition, we explain multi-tenancy

models and the challenges they present in design, implementation, and operations.

Chapter 2, Designing Cloud Applications – An Architect's Perspective, describes familiar

and not-so familiar architectural best practices in the cloud context. These include

designing a multi-tier architecture and designing for multi-tenancy, scalability, and

availability. We will also guide you through the process of estimating your cloud

computing costs.

Chapter 3, AWS Components, Cost Model, and Application Development Environments,

introduces you to the AWS components—EC2, S3, RDS, DynamoDB, SQS Queues,

SNS, and so on. We will discuss strategies to lower your AWS infrastructure

costs and their implications on architectural decisions. We will explain the typical

characteristics of the Development, QA, Staging, and Production environments on

the AWS cloud.

Chapter 4, Designing for and Implementing Scalability, provides guidance on how to

dene your scalability objectives, and then discusses the design and implementation

of specic strategies to achieve scalability.

Chapter 5, Designing for and Implementing High Availability, provides guidance on how

to dene your availability objectives, discuss the nature of failures, and then discuss

the design and implementation of specic strategies to achieve high availability.

In addition, we will describe the approaches that leverage the AWS features and

services for your Disaster Recovery planning.

Chapter 6, Designing for and Implementing Security, provides guidance on how to

dene security objectives, explains your security responsibilities, and then discusses

the implementations of specic best practices for application security.

Chapter 7, Deploying to Production and Going Live, provides guidance on managing

infrastructure, deployments, support, and operations for your cloud application.

In addition, we provide some tips on planning your production Go-Live activities.

What you need for this book

You will need your standard development machine with Spring Tool Suite (STS),

Maven, the Git command line tools, the MySQL database, and an Amazon account

to complete the hands-on sections in this book.
