AWS Administration - The Definitive Guide

By: Yohan Wadia, Naveen Kumar Vijayakumar

Overview of this book

AWS is at the forefront of Cloud Computing today. Many businesses are moving away from traditional datacenters and toward AWS because of its reliability, vast service offerings, lower costs, and high rate of innovation. Because of its versatility and flexible design, AWS can be used to accomplish a variety of simple and complicated tasks such as hosting multitier websites, running large scale parallel processing, content delivery, petabyte storage and archival, and lots more. Whether you are a seasoned sysadmin or a rookie, this book will provide you with all the necessary skills to design, deploy, and manage your applications on the AWS cloud platform. The book guides you through the core AWS services such as IAM, EC2, VPC, RDS, and S3 using a simple real world application hosting example that you can relate to. Each chapter is designed to provide you with the most information possible about a particular AWS service coupled with easy to follow hands-on steps, best practices, tips, and recommendations. By the end of the book, you will be able to create a highly secure, fault tolerant, and scalable environment for your applications to run on.

Plan of attack!

For the purpose of this book, let's assume a simple use case in which a hypothetical company called as All About Dogs (not the best of names I could find) wants to host and manage their e-commerce website on the cloud. As a part of the hosting, the company would like to have the following feature set provided to them by the cloud provider:

  • High availability and fault tolerance

  • On-demand scalability

  • Security

  • Reduced management overheads and costs

Here is a simple, traditional architecture of the proposed website, which basically is a two-tier application primarily consisting of web servers and a backend database, something most IT admins will be familiar with, right? Let's look at the following figure of tradition web service architecture:

This traditional architecture has obvious drawbacks, such as poor scalability, little or no fault tolerance, more management overheads, and so on. Our goal is to leverage AWS's core services and make this obsolete architecture better! Each of the subsequent chapters will show you how to work with and administer these core AWS services keeping our use case in mind. By the end of this book, you should have a fully scalable, resilient, and secure website hosted on the AWS cloud with a design similar to this! Here is the AWS architecture:

Awesome, isn't it! Believe it or not, this is a bare minimum website hosting architecture on AWS. There are still many enhancements and AWS services that you could incorporate here, but I like to keep things nice and clean, so this is what we will stick with for the remainder of this book.

Here's a list of AWS products that we will be incorporating and primarily learning about throughout the book, apart from few other services:

  • Identity and Access Management (IAM)

  • Elastic Compute Cloud (EC2)

  • Elastic Container Service (ECS)

  • Elastic Block Storage (EBS)

  • Amazon Virtual Private Cloud (VPC)

  • Amazon Cloudwatch

  • Autoscaling and Elastic Load Balancing (ELB)

  • Amazon Relational Database Service (RDS)

  • Amazon Simple Storage Service (S3)
