This article seeks to explain the use of State Machines in Red Hat CloudForms for the use in the flow control of automation.
The topic of State Machines is sometimes perceived as rocket science, barely used but often taught. The first thing to dispel is the complexity in state machines, then we can compare how a state machine differs from other process automation like Workflows.
Finally the article is to dispel the myth that State Machines are RUBY or if you use Ansible Automation Inside you do not need state machines, again not a true statement.

In this post, we will show you how to make your service catalog descriptions more elegant and flexible in Red Hat CloudForms. If you just type a description, along with a long description, you’ll get something like this:
This is fine, it’s informative and simple. But we could improve on it.

One of the most interesting features of CloudForms is the ability to define services that can include one or more virtual machines (VMs) or instances and can be deployed across hybrid environments. Services can be made available to users through a self-service portal that allows users to order predefined IT services without IT operations getting involved, thereby delivering on one of the major promises of cloud computing.
The intention of this post is to provide you with step-by-step instructions to get you started with a simple service catalog. After you have gone through the basic concepts, you should have the skills to dive deeper into more complex setups.

To recuperate costs from running a cloud infrastructure, IT organizations often need to charge users for virtual machines they have provisioned. CloudForms contains chargeback functionality that helps facilitate charging users for the resources their virtual machines use. The administrator is able to set rates based on compute, network, and storage resources. Reports can then be run to calculate the chargeback for each virtual machine.
One of the requests customers often have prior to the virtual machine being ordered, is to be able to show the user what the cost of the virtual machine will be.

Very excited about this one, if you have not seen Ravello, check it out http://www.ravellosystems.com, here is a summary…

Whats even cooler, you can actually run hypervisors in AWS, which if you have been playing with EC2 you will know is impossible with them, without some sorcery!

This subject is only the hottest on the block at the moment…why? I guess because InfoBlox is pretty cool, it provides DHCP, DNS and IP Address Management services for any size of network. Its fairly easy to configure and InfoBlox are a good company who allow you to try their software for 60 days eval license. You can integrate using simple RestAPI (there is a Ruby GEM, but I don’t advise using it, I found it problematic, and Rest is so easy anyway!)

CloudFORMS has workflows for many different tasks including approval, quotas and placement to name just a few. This blog entry is going to add to the placement category of workflows. A previous post of mine showed how you could place new workloads NOT_NEAR “Workload Placement by Type (Not Near That)” other workloads which I still think is really cool. This placement workflow is quite simple, it matches template tags against cluster tags. Example;

The guys at Quru have done some really cool stuff with Puppet and CloudFORMS. Here is a re-blog of what they have done,

Use Case – I want that when I provision a virtual machine I can specify certain workload types that I wish to avoid being placed with.
Example 1 – I will be requesting a virtual machine that will be very intensive on CPU or Disk I/O, therefore I want to ensure that I do not place it with any Database Servers, as I may impact their operation or they could equally stave me of resources. But I don’t know where the Database servers are located nor do I care, also real time the database servers are DRS managed therefore they may not be where they were first provisioned!

Enable CloudFORMS to clone a template, and retaining the disk layout. So CloudFORMS currently deploys new virtual machines in RHEV either by PXE or ISO. It does this by cloning a BLANK template and attaching new disks, where a PXE or ISO process will install an operating system. Those from the VMware world and those in Windows land will want to deploy directly from a template a clone, without having to install an operating system, because the template already has it installed in its disk. Reasonable request…. this is how…
