Custom images via boot.rackspace.com:Training wheels included

With the recent announcement of Cloud Images, creating custom images for the Rackspace Public Cloud is now a functionality users have at their disposal.

To simplify the custom image creation process, Rackspace released boot.rackspace.com, a collection of iPXE scripts that allows you to rapidly network boot Operating Systems, Utilities and other tools very easily. It’s especially useful for remote access environments when you don’t want to utilize remote attached CD’s in a Dell DRAC, HP iLO or some other type of remote tool. It’s especially awesome for bootstrapping your own custom installation on a Cloud Server!

Introducing boot.rackspace.com

We have had a number of customers request the need to be able to create their own Cloud Servers images rather than taking snapshots from our base installs. To fulfill this need, we are announcing a new tool as a preview today called boot.rackspace.com. The tool enables you to utilize the various Linux distributions installers to install directly to the disk of your Cloud Server.

Step-by-step walkthrough to using Chef to bootstrap Windows nodes on the Rackspace Cloud

If you are a frequent reader of this blog you will have seen Hart’s posts about “Cooking with Chef”:

Further to these there are also a lot of tutorials on the internet. Most of them seem to focus on using chef to deploy/manage Linux servers but you will have a hard time to find a lot for doing the same on Windows Servers (Yes, Windows as in Microsoft Windows).

I have therefore sat down and put together a detailed step-by-step walkthrough that will guide you through installing your own Open Source Chef Server on a Rackspace Cloud Server running CentOS 6.4, installing the knife-windows plugin and then spinning up, bootstrapping and installing IIS on a Windows Server 2012 Rackspace Cloud Server without logging on to it once. Read on, if you dare…

Welcome to Performance Cloud Servers; have some benchmarks!

Today, all of us at Rackspace are proud to roll out our new Performance Cloud Server offering. These are new flavors of Cloud Servers available to all customers as of today, providing higher performance from RAM to Disk I/O, and more. We’ve also rolled out a significant update to our cloud control panel to greatly improve the user experience of selecting flavors, operating systems and more.

Our Cloud Servers have been completely re-engineered from the ground up to deliver performance and reliability. They are built entirely with RAID 10 protected SSDs and powerful Intel Xeon processors. 40 gigabits per second of highly available network throughput is delivered to every host, enabling high bandwidth applications and blazing fast Cloud Block Storage performance. All hosts have dual power feeds with redundant power supplies and are deployed in Rackspace’s world-class data centers.

But you, as developers, probably want to know more. A lot more. I’ve spent several weeks taking many of the new flavors for a spin, putting them through a variety of benchmarks and stress tests. I’m a developer though and pretty much any time a vendor – even a well meaning one – publishes benchmarks, I want to see the raw data, how to run them and most of all, how I can recreate them, so that’s what I am doing - all raw results, plots, run scripts, etc are on GitHub.

Cloud Databases vs. MySQL on Cloud Servers

If you need to run MySQL on the Rackspace Cloud, you have two fundamental choices: run MySQL on a Cloud Server, or run MySQL as a Cloud Database instance. This naturally raises a few questions: What are the features and benefits of each? Which performs better? Which will be more cost effective? As with every application, the answer is ”it depends;” however, the information below should help you make the right choice based on your needs.

PowerClient: Rackspace Cloud API Powershell Client

Update (July 16, 2015)

As of July 16th 2015, this client has been updated to use JSON requests ONLY. All XML references have been removed at this time. Several new updates have been introduced:

  • Dynamic endpoint URL retrieval from service catalog returned with auth token
