Perforce Puppet vs. Red Hat OpenStack Platform

Puppet is good enough to get the job done, you can use it to automate deployments and maintain files and configurations, if this is all you're looking for it's great. If you're looking for more control over your systems as a whole without having to write your own scripts or install multiple configuration management systems then Puppet is not what you're looking for.

Best suited for - any organization where you have people who already have expertise on OpenStack, Linux & IP networking. Otherwise, the maintenance & operations will be difficult. When the number of deployed VMs reaches its capacity, it becomes very difficult to manage Red Hat OpenStack because there are no in-built fault management & performance management tools available within Red Hat OpenStack. Not suited for - Organizations where people have a culture of working on automated GUI-based tools. Here VMware wins over Red Hat OpenStack. Also where you have mission-critical applications where downtime cannot be tolerated.

• Provides a clear map of how a system is configured
• Eases the creation of a system in a specific cluster as it is scripted in code
• Simplifies configuration changes to a cluster or to every system such as rolling out vhost configurations, updating ldap roles, NFS mounts, etc
• The syntax is very easy to read and carries a lot of fluidity once the language is learned.

• Scaling of application components (VMs).
• Managing the networking between virtual machines.
• Management of VNFs & the underlying infrastructure.
• Availability & uptime of VMs because of features like VM migration & evacuation.

• The setup of Puppet is a nightmare compared to ansible. Anyone watching a youtube video can easily set up ansible with minimal IT knowledge. All one needs is the source IP addresses and we are good to go. Setting up Puppet is a more hands-on task and pushing the puppet agents to all the boxes is another issue. If the installation and setup were simplified like ansible that would attract a lot of people to this platform
• The syntax of the code for Puppet is not as easy as ansible. Ansible simply follows a YAML format and it's like typing in normal English. Even complicated tasks can be written by just understanding YAML syntax. Perhaps Puppet needs to revisit the lanugage used and try to come up with a much simpler lanugage for writing code. This will make day-to-day usage easier.

• User management really needs improvement - when compared to AWS or GCP.
• Security of the overall platform needs to be improved.
• The whole architecture needs to be modular which is not. Ex - Upgrading any particular component (nova, neutron, cinder) should be possible without upgrading the whole Red Hat OpenStack version.
• The creation of HEAT templates for complex applications is still a challenge & has a dependency on external tools.
• Stack creation still requires parameters modification at controllers & compute because of the complex nova-scheduler algorithm.

Puppet has top class support. You can simply mail them with their query and they will respond to your query in a timely manner. We do have enterprise license for puppet. Also there is a vibrant community for puppet out there. So even if you dont purchase a premium support option you can simply google your queries and get answers

HPSA is a licensed product and incurs significant upfront investment costs due to COTS licensing. Puppet Data Center Automation has a significantly lower upfront investment and product documentation is more readily available. Chef is a very similar offering, however, at the time our decision was considered, the adoption of Chef vs. Puppet was significantly less in the community.

Only because of low cost & zero licensing of Red Hat OpenStack

• Cut deployment times down to around 1 hour from 4-5 hours.
• Allows us to get a fully running system up from scratch in around 30 minutes.
• Allows for a more clear view of what is required to get a host running.

• Saved CAPEX for sure (I can't quote a figure).
• Saved Opex also - because a large support community is already available.
• Increased complexity of system setup though.
