I was recently asked to show an example of how Windows Server 2012 running Internet Information Service (IIS) 8 can scale out in an OpenStack environment. I accepted the challenge and this post is the result.  To accomplish the task, I did a default install of an evaluation version of Windows Server 2012 and installed/configured IIS8 along with ASP.net support.  I then created a very simple web page that uses server variables and the current date an time to create some dynamic content.  Lastly, I installed the CloudBase Cloud-Init service so that Windows Server could talk to the OpenStack metadata service.  I hope you enjoy the video.

After a long delay (I was moving into a new house and work keeps me very busy) here is the second part of my post on creating scale out workloads in OpenStack using Heat and Ceilometer.  In part one, we broke down the different parts of the Heat template that we will be using in this part of the posting.  We also covered how I had images and software repos configured to support the WordPress website the template will be deploying.  In this part, we will deploy the application, or stack as it is called in OpenStack lingo, and look at different ways to monitor the application to see what is going on.

Recently, I have been spending a fair amount of time tinkering with Red Hat Enterprise Linux OpenStack Platform 5 (RHEL-OSP 5) which is Red Hat’s Icehouse based offering of OpenStack.  My goal was to learn how to get OpenStack to scale workloads up and down as needed.  Elasticity like this is one of the essential characteristics of cloud computing as defined by the National Institute of Science and Technology (NIST), and is one of the capabilities that OpenStack has that traditional data center virtualization systems typically don’t possess.
