Core Infra User Guide (Rackspace Cloud)

How to use this guide

We created this guide to help you get the most from your Rackspace cloud and especially from its core infrastructure:

  • Cloud Servers
  • Cloud Networks
  • Cloud Images
  • Cloud Block Storage
  • Cloud Files

The guide is meant to simplify your startup process. It doesn’t replace the detailed technical documentation for these services, but it should give you a clear picture of what you can do in the Rackspace cloud.

  • Introducing the Rackspace cloud provides a high-level overview of our core infrastructure, explains how our cloud hosting differs from other kinds of hosting, gives a brief tour of Rackspace cloud services, and connects you to our collection of user stories.
  • Interacting with the cloud suggests several ways of controlling your configuration, including the GUI-based Cloud Control Panel and several CLIs, APIs, and SDKs.
  • Establishing your cloud configuration, focuses on the core infrastructure, providing facts and suggestions to help you quickly establish a useful and manageable cloud configuration.
  • Preparing for productivity specifies pre-production steps you should take to harden your cloud server and make it ready for work.
  • Succeeding in the cloud identifies ongoing responsibilities and suggests special-interest topics that may interest you after you are established in the cloud.


We wrote this guide for you, imagining “you” as someone who:

  • is already a Rackspace customer

We want to help you understand what’s available to you in the Rackspace cloud. You might already be familiar with other Rackspace products and services.

  • knows quite a lot about your own application

We want to show you how your cloud configuration can give you new ways to get your work done. You’ve already decided what that work is.

  • works confidently with computing outside the cloud

We haven’t written an introduction to computing; if we use a term and don’t define it, that’s because we’re using it in an industry-standard way that is clear to you or easy for you to discover.

  • knows a little about cloud computing and now wants to know a lot about cloud computing at Rackspace

We’ll explain key ideas and how they relate to each other. Your situation is unique, and we want to help you recognize topics to investigate and options to pursue as you move your work into the Rackspace managed cloud.

  • is willing to follow links from this brief guide to more detailed Rackspace resources

We’ll point you toward case studies, step-by-step tutorials, API references, and more. As you get started in the Rackspace managed cloud, learning to use supporting information will help you become confident and successful.
