The ultimate focus of a traditional data center/server room is its precious servers. But, to make those servers useful, you'll need to add racks, power supplies, cabling, switches, firewalls, and cooling.

AWS's Elastic Compute Cloud (EC2) is designed to replicate the data center/server room experience as closely as possible. At the center of it all is the EC2 virtual server, known as an instance. But, like the local server room I just described, EC2 provides a range of tools meant to support and enhance your instance's operations.

This chapter will explore the tools and practices used to fully leverage the power of the EC2 ecosystem, including the following:

 Provisioning an EC2 instance with the right hardware resources for your project

 Configuring the right base operating system for your application needs

 Building a secure and effective network environment for your instance

 Adding scripts to run as the instance boots to support (or start) your application

 Choosing the best EC2 pricing model for your needs

 Understanding how to manage and leverage the EC2 instance lifecycle

 Choosing the right storage drive type for your needs

 Securing your EC2 resources using key pairs, security groups, network access lists, and Identity and Access Management (IAM) roles

 Scaling the number of instances up and down to meet changing demand using Auto Scaling

 Accessing your instance as an administrator or end‐user client
